Abstract

Annually 5.6 million tonnes of FVW are produced in India. Anaerobic digestion (AD) holds the potential of generating renewable energy from this organic waste. Therefore, an attempt has been made to optimize inoculum to substrate (I/S) ratio via biochemical methane potential (BMP) of FVW using two different types of inoculums viz. anaerobic sludge and a mixture of anaerobic sludge and cow dung in (1:1) ratio. Different (I/S) ratios selected for the study were 0.2, 0.3, 0.4, 0.5, and 0.6. Results indicated that anaerobic sludge (AS) along with cow dung (CD) at a (1:1) ratio performed better than AS alone. The highest cumulative biogas yield was obtained at (I/S) ratio 0.3 for AS+CD (1:1) ratio, which is equivalent to 468.82 ml/g VS. On the other hand, the biogas yield using only AS was found to be 459.49ml /g VS. The highest methane content was obtained as 64% and 61.2%, for inoculums AS+CD and AS, respectively. Performance analysis portrayed volatile solids (VS) reductions of 74% and 68% for (AS+CD) and AS, respectively. The kinetic parameters of AD were studied by the modified Gompertz model (MGM) and the first-order kinetic model. The experimental data fitted well with the MGM model.

Abstract

Treatment of organic waste has gain importance in the last decade due to stringent environmental laws. Fruit and vegetable waste (FVW) is potent substrate to be utilized for the recover energy via anaerobic digestion, a sustainable approach for the waste to energy transformation. Co-digestion of FVW and anaerobic sludge (AS) was explored in batch anaerobic digestion for a retention time of 31 days. Mixing ratio of (AS:FVW) 25:75 claimed 22% and 43% higher biogas yield as compared to 50:50 and 75: 25 ratio, respectively. Highest methane yield of 62% which is equivalent to 275.9 NmL/g VS was observed for (AS:FVW) 25:75 ratio. Further, application of microwave (MW) treatment enhanced the solubilization of the feedstock and rendered 10% higher methane yield as compared to untreated (AS:FVW) 25:75 ratio at operating power of 300W. Performance analysis indicated highest VS reduction of 77% for MW-treated FVW at optimal ratio of FVW and AS. Kinetic modelling was done, and experimental data fts well to the frst-order model as compared to modifed Gompertz model. Rate constant at optimal ratio with microwave pre-treatment was found to be 0.111, while the value for untreated optimal ratio was found as 0.1085

Abstract

Over the past years, uncontrolled population explosion coupled with an upsurge in the living standard of the people has led to a rise in the generation of municipal solid waste and energy consumption per capita. This has also increased the energy crisis and carbon footprint on the environment. Anaerobic digestion is a mature and sustainable technology for recovering energy from biomass, which can reduce the burden on municipal communities. Hydrolysis and acidogenesis are the ratelimiting steps in anaerobic digestion (AD), which needs to be improved to facilitate quick digestion of the highly biodegradable organic waste such as and fruit and vegetable waste (FVW) and food waste. Optimization of the operating parameters of hydrolysis and acidogensis, particularly for the treatment of FVW, has not been studied in detail so far. Therefore, in our present study, an attempt has been made to optimize the infuence of environmental parameters such as pH and solid-to-liquid (S/L) ratio on VFA and chemical oxygen demand of the leachate through batch test. Infuence of adding waste activated sludge toward enzymatic hydrolysis was also studied. The optimum pH and S/L ratio were found to be 6 and 7%, respectively, for the frst phase of AD. Solubilization rate constant (k) for hydrolysis and acidifcation of FVW was found as 0.1785 d−1. Improving the degree of hydrolysis will enhance the VFA production, which is a precursor of the methanogenesis step, thus enhancing the overall process efciency of AD. Hydrolysis rate was found to increase from 44 to 83%.

Abstract

Anaerobic digestion (AD) is a mature technology for treating organic fraction of municipal solid waste. In the present study, an attempt has been made to evaluate the optimum mixing ratio for co-digestion of two main streams of organic fraction of municipal solid waste (OFMSW) i.e., fruit and vegetable waste (FVW) with food waste (FW) and its efect on biogas yield using single-stage anaerobic digester. The diferent ratios selected for the study were (FVW:FW) (1:1, 1:2, 2:1). The results indicated that (FVW:FW) in the ratio (1:2) gave the highest cumulative biogas yield (510.96 mL/g VS) in comparison to (1:1) (472.2 mL/g VS) and (2:1) (420.5 mL/g VS) ratio, whereas Mono digestion of FVW and FW gave cumulative biogas yield of 429.16 mL/g VS and 393 mL/g VS, respectively. The co-digestion of FVW and FW contributed to the digester’s stability, which improved operation of AD and increased biogas production. The methane content in the digesters was increased from 35 to 67% with the time. The co-digestion of FVW and FW at optimal mix ratio yields 21% higher methane content as compared to mono-digestion of FVW. Performance analysis indicated a volatile solid reduction of 72% at the optimum mix ratio.

Abstract

The depletion of fossil fuels coupled with stringent environmental laws has encouraged us to develop sustainable renewable energy. Due to its numerous benefts, anaerobic digestion (AD) has emerged as an environment-friendly technology. Biogas generated during AD is primarily a mixture of CH4 (65–70%) and CO2 (20–25%) and a potent energy source that can combat the energy crisis in today’s world. Here, an attempt has been made to provide a broad understanding of AD and delineate the efect of various operational parameters infuencing AD. The characteristics of fruit and vegetable waste (FVW) and its feasibility as a potent substrate for AD have been studied. This review also covers traditional challenges in managing FVW via AD, the implementation of various bioreactor systems to manage large amounts of organic waste and their operational boundaries, microbial consortia involved in each phase of digestion, and various strategies to increase biogas production.

Abstract

This study explores the potential application of discarded plastic water bottles, specifically those made of polyethylene terephthalate (PET), as a resource material for reinforcing soil subgrades. These bottles are transformed into strips to demonstrate their suitability for substitution. The research primarily focuses on examining the resilient modulus (Mr) of soil–PET waste mixtures, considering variations in both waste content and size. The inclusion of PET strips significantly affects the Optimum Moisture Content (OMC) and Maximum Dry Density (MDD) of stabilized soil, with higher levels of PET reinforcement leading to a reduction in compaction parameters. The resilient modulus of the soil initially increases with an increase in the proportion of PET strips but eventually begins to decline after reaching a peak, indicating the notable influence of PET reinforcement content on subgrade performance. Furthermore, the dimensions of the PET reinforcement show a moderate impact on the resilient modulus, with significantly higher values observed for strips with a higher length. Overall, this research underscores the importance of resilient modulus in evaluating soil subgrade performance and offers valuable insights into the potential use of waste PET bottles to enhance the strength of weak subgrades prone to vehicle-induced stress.

Abstract

Post-consumer plastic water bottles are foremost source behind the adverse effects on animals and the ambient environment as majority of quantity are dumped without being recycled or reused owing to a lack of awareness or infrastructure. This study explored the possible reuse of such post-consumer plastic water bottles as an admixture for altering the soil subgrade properties. The extent of replacement and sizes of waste material are the key aspects for improving the geotechnical parameters. So, this study focused on investigating the impact of plastic waste content and size through standard compaction, California Bearing Ratio (soaked and unsoaked), expansion ratio, and resilient modulus on stabilized soil subgrade. The series of experiments were conducted by varying the plastic waste content with 0%, 0.2%, 0.4%, 0.8%, and 1% of dry soil and two different sizes of waste strips with aspect ratios 2 and 4. It was discovered that adding plastic waste noticeably improves the behavior of stabilized soil subgrade under extreme conditions. Among the various combinations, laboratory test result of mix with 0.4% plastic content and strips with width 5 mm and length 10 mm shows the significant improvement in strength properties. Thus, this research provides an important approach to use waste plastic bottles for the construction of subgrade in order to lessen harmful impact of waste plastic bottles on living organisms and environment.

Abstract

In recent decades, changes in lifestyle, industrialization, urbanization, migration, etc., affected the ecosystem of the earth due to the generation of postconsumer wastes. The amount of waste generation is leading to a huge challenge for the disposal of wastes. The direct dumping of wastes in water bodies and land created a major impact on ambient. A refined analysis was carried out based on studies available on the effect of natural and synthetic waste materials on the geotechnical properties of soils. This paper presents the review of various types of wastes used as an admixture with soil and its behavior. Looking to the problem of waste dumping, one of the potential use of wastes in developing country is to utilize wastes in ground improvement looking to the large-scale infrastructure construction. The addition of wastes in different amount, form, etc., shows the significant modification in the properties of virgin soil.

Abstract

Plastic waste management becomes a serious issue all over the world. Dumping of plastic waste on land without treating it degraded the properties of parent material. The main objective of this study is to demonstrate the use of plastic waste for improving properties of soil and soil subgrade underlying by aggregate base which is applicable in construction of embankment and flexible pavement respectively. Waste plastic water bottles converted into plastic strips with an aspect ratio of 6%. The behavior of randomly distributed plastic strip-reinforced soil system and soil aggregate system was observed by conducting soaked CBR test series with different percentage of plastic strips (0%, 0.5%, 1% and 2%). Results of study show that soil reinforced with waste plastic strips has significant increase in CBR values with respect to unreinforced soil in both the cases. The results also reveal that the 1% of plastic strip-reinforced soil system and soil aggregate system show significant improvement in strength.

Abstract

The subgrade soil is an integral part of pavements which provides support to the pavement. The behaviour of road surface depends on the strength of filling material and the subgrade below it. The pavements are vulnerably affected by the change in subgrade soil properties due to water-table fluctuation, overloading, flooding, etc. This study focuses on improving the strength of soil subgrade using plastic waste soil reinforcement technique in pavement construction, looking to the current environmental issue related to the utilisation of waste plastic, as plastic is a non-biodegradable material. In this study, geocell and geogrid were prepared from plastic waste and used as soil reinforcement. The plastic waste geocell and geogrid were placed at different depths from the top of the CBR mould. The CBR test was performed for unsoaked condition of virgin soil and reinforced soil, and the behaviour of load versus penetration was observed. The results show that by placing plastic waste reinforcement at different depths, the strength of the reinforced subgrade soil considerably increased with respect to virgin soil. The confined structure of plastic waste geocell shows significant strength improvement compared to plastic waste geogrid. The result shows that the significant improvement in strength of soil using geogrid and geocell was effective at a particular depth. This study reveals that the use of plastic waste for improving subgrade soil strength is a good option. The plastic waste can be utilised in pavement construction as well as it can be the cost-effective solution.

Abstract

Infrastructure development is important for developing country like India. Road construction plays a major role in it. Hence, good quality roads are necessary for any type of infrastructure development. Flexible pavements are divided in to layers, which consists of subgrade layer (soil as a foundation), sub-base layer, base course layer and surface course layer (bituminous layer). If any layer becomes unstable or weak, it may lead to failure of the pavement. It is observed that, sometimes pavements fail due to low strength of subgrade soil .The subgrade soil is internal part of the pavement. Hence, sound understanding of the properties of soil subgrade is essential for designing a pavement. The properties of soil can be modified by mixing the fiber rein for cements in the subgrade soil. Natural fibers like coir, jute, bamboo have been used to change the index properties of soil. The expansive soil which is also known as problematic soil was selected for the study. Pavement construction on such type of soil is a major problem. In this paper, coir fibres are used as reinforcement and its effects on the various index properties, i.e. Optimum Moisture Content (OMC), Maximum Dry Density (MDD), Unconfined Compressive Strength (UCS), Swell Pressure and California Bearing Ratio (CBR) are studied. The study also includes effect of percentage reinforcement on the subgrade soil for the pavement design. The pavement design for soil and coir fiber mixture results in to decrease the thickness of subgrade layer.

Abstract

This study presents a comprehensive approach to flood risk assessment and mapping in the Uttarakhand region, India, by integrating geographic information system (GIS) and multi-criteria decision-making (MCDM). The methodology involves using digital elevation models (DEMs) to categorise elevation into five classes, slope analysis to evaluate the role of terrain steepness and drainage density assessment to identify areas less susceptible to flooding. Average annual rainfall data, classified from meteorological stations, land use/land cover patterns and distances from rivers and roads, were analysed within a GIS framework to assess flood susceptibility. The analytic hierarchy process (AHP) was employed to assign weights to these criteria and generate a flood risk index (FRI) map. Key findings indicate that extensive moderate-to-high-risk zones are present, particularly in the lower regions of Uttarakhand. The weighted overlay analysis using GIS and AHP effectively identified areas at greater risk of flooding. The results offer valuable insights for flood risk management, land-use planning and disaster preparedness, highlighting the need for targeted interventions to enhance flood resilience in the region.

Abstract

India's diverse geography presents significant flood risks, analyzed in this study using geographic information systems and multi-criteria decision analysis. This comprehensive flood risk assessment considers seven parameters: mean annual precipitation, elevation, slope, drainage density (DD), land use and land cover, proximity to roads, and distance to rivers. The findings indicate that flood vulnerability is primarily influenced by rainfall, elevation, and slope, with DD, land use, and proximity to roads and rivers also playing crucial roles. Experts weighed these factors to create a thorough flood risk map using the normalized rank index and normalized weight index, categorizing areas into five risk levels: very high, high, moderate, low, and very low. The study reveals that 3.40% of the area is at very high risk, 32.65% at high risk, 39.72% at moderate risk, 20.97% at low risk, and 3.25% at very low risk. These results highlight how human and natural factors interact to influence flood risk, with vulnerable areas characterized by low elevations, steep slopes, high drainage densities, and proximity to rivers or roads. The findings provide valuable insights for policymakers, scientists, and local authorities to develop strategies to mitigate flood losses across India's varied landscapes.

Abstract

Flooding poses a severe threat to communities and infrastructure worldwide, which requires advanced flood forecasting warning systems. In this research paper, a real-time flood forecasting and warning system for the Dharoi Dam in the state of Gujarat, India is developed. This novel system combines ensemble techniques and hydrological modeling simulations to enhance flood prediction accuracy and provides a timely warning. The study focuses on critical gaps in the current flood forecasting capabilities, recognizes the need for improved flood management in the region, and builds upon the existing research conducted globally and in India. The real-time flood forecasting and warning system uses information from various sources such as rainfall, river flows, and water level observations. The system enhances the accuracy of flood forecasts with a 1–5-day lead time by utilizing ensemble techniques, which incorporate multiple models and their corresponding forecasts. The 2-day and 3-day lead times combined with postprocessing techniques yield excellent results, as evidenced by the reservoir inflow correlation value of 0.86 and the receiver operating characteristic-area under the curve (ROC-AUC) value of 0.93. This work aims to reduce the impact of floods in this region and can be used by decision-makers as a disaster management tool.

Abstract

Massive property damage and loss of life have resulted from flooding, which is a common occurrence in many regions of the world, particularly in the developing world. A flood occurs when water from a stream or river overflows its banks and submerges normally dry terrain. Future development and flood mitigation methods rely heavily on understanding flooding behavior and hydraulic features of rivers. The main objective of the research is to simulate the flood event for Lower Narmada River Basin and develop inundation maps. A hydraulic model was utilized in this research to examine a variety of physical variables that are critical to water movement in the river. A digital elevation model (DEM) was used for geometry data generation in ArcGIS, a Geographical Information System (GIS) program, is used to segment the research region for the hydraulic model. Because of this, it makes use of a hydraulic model developed by Hydrologic Engineering Center (HEC-RAS). HEC-GeoRAS is an intermediary module that allows data to be migrated between ArcGIS and HEC-RAS. Flood inundation maps are generated by adding flow data into a model once the necessary geometrical and hydraulic structural data have been gathered and compiled as needed. As a result of hydraulic modeling, flood depth and velocity are also determined. It is necessary to consider flood inundation, depth, and velocity statistics in order to identify flood-prone regions. By using the information from this study, we may better prepare for floods by building an embankment, a flood wall, and other flood mitigation measures. Hydrologists and water resources engineers may utilize the results and findings to plan and develop using the HEC-RAS model, which has excellent performance.

Abstract

Extreme rainfall and sea-level rise due to climate change may have disastrous consequences. In order to take action on the city’s issues with climate change, a new approach called flood resilient urban design was created. Floods caused by global warming and urban growth prompt cities to have various disaster response and preparation strategies included in their master planning efforts. In order to decrease risk, susceptibility and general disaster preparation, it is essential to include the improvement of flood resilience in development planning. Natural disasters cause damage in many sectors such as water management, energy, ecosystems and health. An efficient water management system keeps cities safe from floods and droughts. For flood damage reduction, several regulation methods and public-private collaboration are being used for people’s safety. This chapter proposes a novel flood management plan and land use planning techniques in response to urban flooding. The most significant hydraulic construction constructed on rivers is a dam. It is also a well-known truth that dam collapse causes catastrophe in the downstream river reach, resulting in the loss of human life, property and economic resources. As a result, it is critical to conduct research and develop a flood mitigation strategy for the metropolitan city downstream of each dam and determine the region that would be flooded in the worst-case scenario of a dam collapse. This chapter focuses on research being conducted for Ahmedabad, situated in the lower basin of the Sabarmati River, India. This research will aid in the development of an emergency action plan for the evacuation of the general population and minimising property damage.

Abstract

Rainfall has a direct effect on agriculture, hydroelectric generation, and water resources management, etc. Many natural catastrophes are also closely linked to rainfall intensity and duration, including flood and drought. Therefore, it is essential to have fast and reliable technique of forecasting rainfall intensity and duration for regional water resource management. Timely rainfall forecasting is also required to avoid and mitigate potential harmful impacts of natural catastrophes such as landslides, floods, and droughts. Rainfall prediction is usually based on numerical weather models combined with meteorological radar data. Such models have been used extensively in studies, including multiple regressions and climatology averaging techniques, numerical methods, and empirical formulations. Forecast accuracy depends on uncertainty, and probabilistic forecasting handles the challenge of unpredictability better than deterministic predictions. The behavior of Random Forest, Gradient Boosting, and Decision tree models has been studied to optimize the results generated from data fed into them.

Abstract

Flooding is the most prevalent natural disaster globally. Increasing flood frequency affects developing nations as these countries lack strong forecasting systems. The most flood-prone urban regions are near the coast or riverbanks. Using The International Grand Global Ensemble (TIGGE) data, a coupled atmospheric-hydrologic ensemble flood forecasting model for the Sabarmati river was developed. Incorporating numerical weather prediction (NWP) information into flood forecasting systems can increase lead times from hours to days. When predicting the weather, we employed numerous NWP models from various prediction centers. European Center for Medium Range Weather Forecasts (ECMWF), United Kingdom Meteorological Office (UKMO) and National Centers for Environmental Prediction (NCEP) data with a 5-day advance time are coupled with the HEC-HMS model to provide ensemble stream flow predictions. The ensemble flood forecasting model uses the 2015 flood season as a test scenario. In this research, we discovered that TIGGE ensemble prediction data can be useful for prediction of stream flow and results showed effective flood forecasting for Sabarmati river. HEC-HMS, a semi-distributed hydrologic model, uses ECMWF, NCEP, and UKMO precipitation ensembles. ECMWF shows that 90% of the correlation with observed data and peak time and peak discharge is also match with the observed discharge with a peak on 29 July 2015 with 9,300 cumecs. Danger probability may be accurately predicted based on peak time and flood warning probability distributions.

Abstract

Globally, cities are feeling the effects of climate change: rising temperatures, droughts, heatwaves, and more extreme storms are impacting water quantity and water quality. Roughly half of the world’s population are now living in cities. By the year 2050, that figure is anticipated to rise to as much as 80 per cent. If we want our cities to be sustainable both locally and globally, we need to make sure that we use fewer natural resources and generate less trash. The built environment of a smart city incorporates digital, human, and physical components. It is critical to discover appropriate assessment procedures given the rapid urbanization and wide-ranging innovations. Due to impending scarcity, we must move now to increase water treatment and distribution efficiency while decreasing consumption. Risk assessment, mitigation, warning, and forecasting are all critical components of flood risk management going forward. Institutional and governance measures are also important. By providing fresh insights, this research contributes to the corpus of knowledge on smart city mobility. A smart water city improves the quality of life of citizens by solving existing urban water problems based on various technologies and ICT technologies throughout the urban water cycle. It not only provides individual solutions for conventional water management, such as drainage, water treatment, and wastewater treatment, but also improves comprehensive water management through the restoration of the urban water cycle, waterfront usage, and intelligent water management. Furthermore, in a smart water city, ICT-based intelligent technologies complement and improve existing infrastructure and technologies for water management within the whole urban system. They are a supportive tool for the different functions of water in urban settings. This understanding highlights that smart water cities concern not only the provision of drinking water and sanitation services for urban water users, but also other urban water functions such as urban water restoration, waterfront usage, and integrated water management. This paper examined the use of integrated, real-time information and ICT solutions, such as sensors, monitors, geographic information system (GIS), satellite mapping, and other contactless, intelligent tools in both urban and agriculture water management. The paper presents evidence of how SWM has provided solutions at different scales and across various urban and rural contexts, and how they have impacted the social, economic, environmental, governance, and technological spheres.

Abstract

In 2019, air pollution was the fourth-largest cause of early death globally. COVID-19 was declared a pandemic in March 2020, resulting in significant economic limitations and drastic changes in human behaviour. Lockdown, social distance, disconnection, and residential isolation are being used to combat the COVID-19 pandemic. However, during the COVID-19 pandemic, an unusually beneficial influence on global air-contamination levels is remarkable. Specifically, experts have predicted a major improvement in air quality and a large reduction in the concentrations of several dangerous gases such as SO2, NO2, CO, and O3. The effects of COVID-19 shutdown on the air quality of the world’s major nations India, China, USA, UK, Australia, Asian countries is considered for the study in this chapter. This chapter focuses on the air quality improvement due to COVID-19 lockdown and positive effects on the environment by using the Air Quality Index (AQI) to represent the pollution level at specific cities for the year 2020 and the previous year 2019 on various harmful gases SO2, NO2, CO, O3, and particulate matters PM2.5 and PM10. This chapter will provide significant information to environmentalists and specialists who will use it to develop future legislation to improve air quality and the environment. Compared to 2019, air quality improved in 67% of worldwide cities in 2020 during COVID-19 lockdown.

Abstract

Ground water is the water contained in the soil pores under the earth’s crust. The challenges of ground water shortages and contamination have become worse in recent decades as a result of population development. Traditional approaches for groundwater conservation, such as groundwater based surveys, exploratory exploration, and geophysical techniques, are not only inefficient yet often time consuming. As a result, an advanced Remote Sensing and Geographic Information System (GIS) approach is used. Ground water management may be divided into distinct Potential Zones based on the amount of ground water accessible in a given region. Using Remote Sensing and GIS, any area’s ground water potential zone can be calculated by combining tiff maps and assigning ranks and weightages to each parameter. Slope, drainage density, geomorphology, Lineament Density, Soil, Lithology, and LULC (Land Use Land Cover) are the parameters used to determine the possible zone of ground water in any given region. This paper describes the work that went into determining the GW potential zone in Gujarat’s Saurashtra region. The area from which ground water can be readily accessed can be determined using the Ground Water Potential Zone chart, and this information can be used to dig wells and create hydrological structures.

Abstract

The rivers play a very important role within the lives of the people, because the Rivers are very much helpful in water supply, irrigation, water transportation, generation of electricity, and tourism. Most of the major cities are situated on the shores of holy rivers or near the coastal area. Depleting the status of water resources could also be one among the foremost critical resource problems with the twenty-first century. The country’s rivers must be interconnected to provide water to the drought-prone areas. The method is designed to preserve river water that flows into the ocean every year during the monsoon season. The study focuses on interlinking key rivers in Gujarat to meet the requirements of regions with severe water shortage such as North Gujarat, Saurashtra, and Kutch. This article proposes a sustainable resilient strategy for river water interlinking, which helps manage surface water storage and salty water intrusion into coastal groundwater. The planned unlined canal is intended for low silting and scouring. The canal’s bottom width is 152 m and its depth is 5.4 m. This canal will act as a multifunctional strategy to solve different water problems while also affecting the environment.

Abstract

Most of the natural disasters are unpredictable, but the most frequent occurring catastrophic event over the globe is flood. Developing countries are severely affected by the floods because of the high frequencies of floods. The developing countries do not have good forecasting system compared to the developed country. The metro cities are also settled near the coast or river bank which are the most vulnerable places to floods. This study proposes plan for street level flood monitoring and warning system for the Surat city, India. Waterlogging happens in the low lying area of the Surat city due to heavy storm and heavy releases from the Ukai dam. The high releases from upstream Ukai dam and heavy rainfall resulted into flooding in the low lying area of the Surat city. This research proposed a wireless water level sensor network system for the street water level flood monitoring. The system is proposed to monitor the water levels of different areas of city through the wireless water level sensors as well as to capture live photos using CCTV camera. This will help authority not only to issue flood warning but also to plan flood mitigation measures and evacuation of people.

Abstract

Rivers are critical to human life because they are strategically significant in the world, providing primary water supplies for various purposes. Rivers are the prime importance of any country as most of the cities are settled near the river. Due to developmental activities and increase in population, it will result in huge waste generation. Surface water quality is affected because of increasing urbanization and industrialization. The aim of this research is to examine the effect of climate change and industrialization on the water quality of the Sabarmati river using a mathematical model. For this study, four important towns along the lower Sabarmati River have been considered and water quality data was considered from 2005 to 2015. In this study, different water quality parameters were considered to derive a water quality model. Results show the water quality downstream after Ahmedabad city is worse compared to the other location where the Maximum WQI is 0.71 at Rasikapur and average WQI is 0.50 for the same location for the last 15 years. It has been observed that the effect of the monsoon and also by comparing time scale water quality model the role of regulations for industrialization also plays an important role in the quality of Sabarmati river.

Abstract

Agriculture is the primary source of income for the majority of India's people. Big farmers in India use inorganic fertilisers and pesticides on their plantations. However, it would reduce soil fertility. So, in order to address this problem, this paper encourages farmers to return to organic farming, while still increasing crop yield and decreasing crop water requirements. Nano materials and different bio fertilizers were used to cultivate the groundnut crop. For this, we applied these fertilisers to one acre of land for crop production, whereas on the other hand, we applied simple organic fertilisers and water to another one acre of land for comparison. The key goal is to increase yield with high-quality groundnuts. The use of these Nano organic products results in a 17-20% increase in overall production, and the cost-benefit ratio is 1.98, which is very good as compared to conventional inorganic farming.

Abstract

Day after day, the need for potable water rises and the amount of potable water available decreases at the same time. Around 97 percent of all the water on Earth is saline water in the oceans and aquifers. There is only 2.5–2.75 percent of fresh water available, including 1.75–2 percent frozen ice glacier, 0.5–0.75 percent fresh groundwater and less than 0.01 percent surface water in lakes, swamps and rivers. Fresh water is renewable and variable; it is a restricted commodity, however. Only by the water cycle, in which water from seas, streams, soil, rivers and reservoirs evaporates, creates clouds and returns as precipitation, can fresh water be replenished. 0.003 per cent of absolute water is fresh and unpolluted water. In India many villages and communities still rely on river water for drinking purposes but the water available in river is majorly polluted due to human activities. The ocean water which is available in huge quantity comes to rescue in this scenario. The saline water of ocean can be converted into drinkable water using solar energy in an affordable manner. This paper describes a unit which is designed on simple principles of evaporation and condensation with no electricity being used. Thus we harness the heat radiated by the sun to accomplish the evaporation segment. The water will be condensed by natural temperature difference between heated and non-heated segment. The unique aspect of this paper is the use of convex lenses to heat the water initially from the tank such that the water being heated by the sheet evaporates at an increased rate due to the incoming water having an elevated temperature.

Abstract

The population of Indian cities is increasing exponentially, which results in the use of more resources and on the other side, the generation of waste will also increase. The most commonly used masonry unit of a building material is brick. To overcome this issue of resource utilization and waste generation, civil engineers have been facing challenges to find a better solution. Research was carried out to obtain a useful construction and building material in the form of slu-brick from solid waste (sludge). Improper disposal of domestic sludge causes harmful effects on the environment that poses a major problem in urban cities. This study focuses on the use of sludge in production of brick since the chemical composition of sludge is similar to that of clay. Different series of sludge and various ingredients mixture proportions were studied where in varying sludge ratios starting from 5% to 30% of the total weight of mixture was added. Various physical test were carried out such as specific gravity, compressive strength, water absorption, fineness test as well as an environmental test were also conducted such as total coliform and E-Coli content. While testing various parameters it has been observed that slu-brick is good enough to use as construction materials compared to conventional brick as its strength is similar to the conventional brick when the sludge content is 30%. It was observed that good quality slu-brick can be produced up to 30% utilization of sludge in brick making. This study confirms that the waste sludge can act as a suitable material in the manufacture of slu-brick with proportionate mix and design. Thus to an extent clay can be replaced with sludge in the brick manufacturing, which helps in the conservation of naturally available resources and improves the environmental quality.

Abstract

Even though water is abundantly available, the quantity of water available for direct use is very limited. At the another side, the quality of available water is also deteriorating because daily activities of human increase the load of pollutants which deteriorated the quality of surface as well as ground water also. Ultimately results in the reduction of usable quantity and quality of water. Moreover, water bodies such as lake is used for storage of water but in India, people dump their wastes in lakes which results into eutrophication of lake. Research was conducted on the lake water of Ambapur (unlined-rural) and Bopal (lined-urban) where water is available in large quantities but at the same time it is not useful for domestic purpose. Which lead to an adverse impact on biotic and abiotic environment of the surrounding area of particular place. Various tests (physical, chemical and biological) were performed to determine the extent of the pollutants and the viable ways to reduce this pollution were explored. Emphasis were made to inculcate more of the locally available materials which would result in a sustainable as well as cost-effective solution. Thus, in this research several experiments were conducted for the treatment of lake water with the usage of vetiver grass, conventional sand, rice husk, coconut fibers, activated carbon, oysters and moringa seeds. These layers will remove most of the impurities and pollutants form the contaminated lake water and tests were again performed to check whether the water is useful for domestic purpose or not? The results shows that this treatment methods can remove most of the pollutants and also the treatment is very economical as this method uses locally available materials.

Abstract

Flood is natural disaster which is occurring in almost every part of the country. Total of 30 years (1985-2016) hydrological data has been given as an input to the model study. In order to run HEC-HMS model for assessment of flood at Surat outlet of Tapi river basin the input such as Rainfall, soil map and land use/land cover map required are extracted from soil. The hydrology of the area is characterised by high interaction between ground water and surface water. Input files were prepared using HEC-GeoHMS and later imported to HEC-HMS along with the meteorological and hydrological data to calculate run-off at the watershed outlet. Analysis was carried out in HEC-HMS to determine peak stream flow and occurrence time. SCS (Soil Conservation service) method can be used for flood stimulation in HEC-HMS. From the values of R2 (coefficient of determination) and from stimulated Qpeak (discharge) and observed Qpeak the flood model can be derived in HEC-HMS. Satellite image of area near Tapi region is selected and with the help of software we could analyse the flood prone areas. Parameters like population Density, resources availability, Elevation of geographical area, etc. database can be collected using GIS. Software like ArcGIS can be used to get the data of flood. From the data obtained using HEC-HMS and GIS the area of surat are divided into High risk and Low risk zones. Based on this study it will be helpful in identification of low lying & flood prone areas in Surat city and also helpful in Surat urban planning near Tapi River.

Abstract

The quality of river water is enfeebling day by day due act of increasing urbanization and industrialization in Ahmedabad city. The surface and sub-surface water samples were collected from different locations along the length of Sabarmati river. In this study water samples from six different sites namely Sant-sarovar, Gandhi Bridge, Vasna Barrage, Vasna-Narol Bridge, Miroli Pumping station and Vautha Bridge along the Sabarmati river basin were collected and numerous physical test like pH, turbidity, temperature, electrical conductivity, TDS and chemical test like alkalinity, chloride content, sulphate content, hardness, BOD, COD, Dissolved Oxygen and biological test such as E-coli and total Coliform were performed to determine WQI (Water Quality Index) of the Sabarmati river. WQI is one of the most effective tools to communicate information on the quality of water to the concerned citizens and policy makers or water resource managers. Water Quality Index allows for a general analysis of water quality on many levels that affect a stream’s ability to host life and whether the overall quality of water bodies poses a potential threat to various uses of water. The results of each test is graphically represented for simplification. The sites located in highly urban area showed the worst water quality followed by the station located in moderately urban area and lastly station located in a moderately rural area. Water quality index combines all the different water quality parameter and communicates the facts to the individuals concerned. The main cause of deterioration in water quality at these monitoring stations was due to the high anthropogenic activities, illegal discharge of sewage and industrial effluent, lack of proper sanitation, unprotected river sites, and urban runoff.

Abstract

This research developed a small-scale flood model that integrates Geographic Information and hydrological models. HEC-RAS model helped in simulation and to develop a relationship between runoff and rainfall in Banas River, Gujarat, India. Banas River has been taken as the study area because it is a region which was mostly flooded and having a severe effect on the Gujarat 2017 flood. This model compromises two models, a rainfall-runoff model that converts rainfall excess to surface flow and river runoff, and a second model as a hydraulic model that covers unsteady state flow through the river channel network. In HEC-RAS model, new GIS tool RAS Mapper has been used which is compatible with GIS facilities and modelling has been done with this tool. Results are also available in different parameters such as flood inundation depth, flood water velocity and time. Validation of the model is important, the results at the end of the simulation were compared with the previous observed flood water level data from past flood events in a particular fixed location. The results of this research will benefit in flood management and also used in future modelling for flood disaster forecasts.

Abstract

Composite structures are becoming a part of modern construction practice. Composite columns sections such as Concrete Filled Tube (CFT), Concrete Filled Double Skinned Tube (CFDST), Concrete Encased Steel (CES), etc. have made the high rise buildings and long bridges, reasonably safer and lighter. Newly evolved CFDST sections, where concrete sandwiched between two steel tubes has shown improved performance under earthquake loading. The concrete infill enhances the load carrying capacity & energy absorption and limits steel tube to get locally buckled. Furthermore, these sections provide high bending stiffness, better local and global stability and enhanced post peak behavior. Currently, in many countries like China and America, composite structures are constructed in a considerable extent. However, in India, utilization of composite columns is very limited because of lack of committed Indian standard stipulations. Acknowledging multifaceted nature in investigative answer for column element, utilization of Load - Moment (P - M) interaction curve plays a crucial role in design of composite column. Currently, available composite structure design codes predict the load – moment capacity based on either plastic design or strain compatibility design method. The present study aims to develop theoretical formulations for design of Circular Concrete Filled Double Skinned Tube (C-CFDST) composite column section using plastic method of design approach following Eurocode-4. Computer Aid has been developed in Visual Studio 2019 with VB .net language based on proposed theoretical formulations to have a great advantage of computers in obtaining a solution for such complicated problems.

Abstract

Concrete Filled Double Skinned Steel Tubular (CFDST) composite column comprising of outer and inner steel tubes is a class of CFST composite columns developed for improved structural performance and is evolving. Experimental studies conducted on CFDST column test specimens, hitherto, were very limited and mostly under axial loading. An experimental investigation has been carried out on a total 9 nos. of CFDST composite column test specimens under axial-flexural loading. Parametric study has been performed considering outer square steel tubes with inner steel tubes of circular and diagonally oriented square shapes as well as without inner steel tubes of square and circular shapes. Parameters of concern; D/t ratio and confinement of concrete sandwiched between steel tubes were examined. An effective loading mechanism, utilizing the full length of the test specimen, has been developed. Ultimate load carrying capacity, longitudinal and lateral strain as well as axial and lateral displacement were extracted for CFDST columns. Ultimate load carrying capacity of the square CFDST column increases by ~11% vis-à-vis square CFST column under axial loading. CFDST columns yield maximum reduction of ~45% in ultimate load carrying capacity with increase in eccentricity per se axial loading. Shape and orientation of inner square steel tube w.r.t outer square steel tube does not have detrimental effect on axial load carrying capacity of the CFDST columns. Absence of inner tube in CFDST columns show reduction of ~18% in ultimate load carrying capacity. CFDST columns tested with different D/t ratio under concentric loading revealed that ultimate load carrying capacity reduces by ~34% with increase in D/t ratio. CFDST columns under concentric loading show presence of concrete confinement at an early stage of loading ~20-40% of the peak load, however the same is achieved at loading stage ~60-80% of the peak load for higher D/t ratio test specimens.

Abstract

Axial – flexural behaviour of Concrete Filled Steel Tubular (CFST) column specimens utilizing routinely used Indian hollow steel tube sections is investigated. Eighteen test specimens comprising of circular, square and rectangular geometrical shapes are considered. A simple mechanism is developed with pinned end conditions to utilize full testing length of slender CFST column. Maximum load, axial shortening and lateral displacement parameters are evaluated to quantify axial-flexural behaviour of slender CFST column test specimens. Normalized ratios in terms of confinement factor, steel and concrete contribution ratio, ductility index, strength index and load carrying capacity are estimated to study efficacy of geometrical shapes of CFST column test specimens. It has been found that square CFST column outperforms circular and rectangular CFST column for resisting maximum load with global buckling as predominant mode of failure. The maximum load carrying capacity of circular, square and rectangular CFST test specimens under concentric loading is found to reduce for eccentric loading with increased eccentricity. Concentrically loaded CFST column test specimens show local buckling as predominant failure against global buckling failure under eccentric loading. Design code EC4 estimates load and moment for CFST column test specimens in close agreement to experimental values. Dissection of the CFST test specimens reveal that concrete infilled hollow steel tube cracked due to tensile and compressive stresses ensuring perfect bond assumption between steel and concrete elements.

Abstract

On day to day basis structural designer comes across design of Non-Rectangular Reinforced Concrete (RC) Column. Commonly the design of Non-Rectangular RC column except the circular section dealt with considering equivalent rectangular section due to limitation of codal stipulation IS 456:2000. A need has been realised to develop design aid for Non-Rectangular RC column which involve iterative & tedious design calculations. This paper aims to design Non-Rectangular RC short/slender column - C Shape, from first principle for axial load and biaxial bending moment. Apart computer module is developed in Visual studio 2012 for quick calculation, validation of Axial-Flexure (P-M) interaction diagram of developed computer program is carried out by comparing it with well-established computer program SAP 2000.

Abstract

Brick is one of the most used building materials in masonry construction. Conventionally burnt clay bricks are used. These bricks are manufactured from clay and burnt in a kiln at a higher temperature. This results in a very high amount of CO2 emission and has high embodied energy, which highly affects the environment. Compressed bricks are one of the sustainable solutions to overcome these issues of high CO2 emission and embodied energy. Adopting sustainable alter- natives, such as compressed bricks incorporating supplementary cementitious materials or envi- ronmentally friendly brick manufacturing processes, can help mitigate these issues and promote more sustainable construction practices. In this study, attempts have been made to manufacture and test the bricks with different proportions of the soil, i.e., the mix of locally available soil with sand, cement as the cementitious materials, and SCMs like fly ash & GGBS. The research methodology involves the formulation of different mixtures with varying proportions of SCMs. The specimens were then prepared using a compression molding technique and cured under controlled conditions. This research paper aims to investigate the effects of incorporating sup- plementary cementitious materials (SCMs) on the properties of compressed bricks. The study focuses on evaluating the density, compressive strength, water absorption, and efflorescence, as well as calculating the embodied energy and carbon dioxide emissions associated with the pro- duction of these bricks. Furthermore, the paper comprehensively analyzes the embodied energy and CO2 emissions associated with producing compressed bricks. These calculations consider the energy consumed and CO2 emitted in manufacturing, including raw material extraction, transportation, and brick fabrication. The study's results demonstrate the influence of SCMs on the properties of the compressed bricks. The analysis of embodied energy and CO2 emissions provided valuable insights into the environmental sustainability of the brick production process.

Abstract

The enormous population growth brings some environmental concerns due to the need for exploitation of natural resources, and the implementation of recycling programmes is a fundamental element for achieving sustainable development. Natural well-graded readily draining granular materials such as sand are commonly employed as filling materials for various geotechnical structures. But, because of the shortage of perfect granular materials, the researchers were forced to look into other options. However, because granular material is in high demand, unlawful sand dredging from riverbeds is becoming more popular. The construction sector generates a huge amount of construction and demolition waste (CDW) in India and other areas of the world, which is created by operations such as demolition, excavation, site preparation and other activities. The paper highlights the possibility of using CDW as a sustainable reinforced backfill material for retaining walls. The geotechnical properties of CDW, soil and mixture of both were determined and observed that it meets the requirements of backfill material for retaining walls. Further, the numerical studies were conducted to study the static and dynamic behaviour of retaining walls with an optimum dosage of CDW in soil for backfill, using a finite element (FE) analysis GEO5 software. The paper emphasises the potential application of CDW as a sustainable reinforced backfill material for retaining walls in dynamic condition.

Abstract

India requires a large landfill area for the disposal of construction and demolition waste (C&DW) generated during maintenance, renovation, or destruction of different structures. India produces millions of tonnes of C&DW and the capacity for recycling is less than 2 percent. As a result, India must establish a strategy for reducing, reusing, and recycling C&DW. This study presents the efficacy for use of C&DW as a reinforced material to be mixed with backfill soil in retaining walls. Various index and engineering properties of soil and C&DW, including compaction parameters, and shear parameters are determined and compared for different C&DW and soil proportions. The compaction tests and triaxial compression test showed that the best results are achieved with 37.5% replacement of soil by C&DW. When 37.5% of soil is replaced by C&DW, the Optimum moisture content and maximum dry unit weight values were observed to be increased by 6.95% and 2.06%, respectively, while the cohesion decreased by 30.35% and the internal friction angle increased by 85.44%. The study emphasizes the potential application of C&DW as a reinforcing material in the backfill of the retaining walls.

Abstract

In this work, waste plastics have been used with bentonite clay to produce silica-containing graphene nanosheets (GNs) for adsorption of nitrate and phosphate from synthetic water. The GNs were obtained by the two steps process, namely (1) pyrolysis at 750 °C and (2) ball milling. Then, GNs were characterized by Raman spectroscopy, FTIR, XRD, FESEM, HRTEM and EDX spectroscopy, which provided the details of material's morphology, surface properties, and composition. From Raman spectroscopy, D and G bands were found at 1342 cm−1 and 1594 cm−1, respectively, which confirmed the presence of nanosheets on the graphene surface. Furthermore, the layers of nanosheets were confirmed by the HRTEM analysis and XRD peaks. In analytical study, the batch experiment was conducted to investigate the influence of operational parameters such as pH (03–12), contact time (05–120 min), adsorbent dosage (0.01–0.06 g), and initial concentrations of adsorbates (10–50 mg/L for nitrate and 03–15 mg/L for phosphate) on adsorption process. The removal percentage of nitrate and phosphate at optimum dosage = 0.05 g, pH = 6.5, contact time = 60 min, nitrate concentration = 30 mg/L, and phosphate concentration = 09 mg/L were found to be 85 and 91, respectively. The highest adsorption capacity of nitrate and phosphate was found to be 53 mg/g and 16.4 mg/g, respectively. The adsorption behaviour of both nitrate and phosphate showed chemisorption as the experimental data were well fitted by the pseudo-2nd-order kinetic and Langmuir isotherm model. Life cycle cost analysis (LCCA) of the synthesis process was conducted to evaluate the cost-benefit analysis for commercial feasibility. The estimated price for the synthesis of GNs using 1 kg of waste plastics and bentonite clay as precursor was $4.21, suggesting commercialization.

Abstract

The fundamental natural period of oscillation is a critical parameter in evaluating the design base shear of buildings. Worldwide seismic design codes typically employ height-based empirical formulas to estimate this period for various building categories, without distinguishing between regular and irregular buildings. This study proposes a formula specifically for reinforced concrete (RC) moment-resisting frame (MRF) buildings with dominant re-entrant corner type plan irregularity. A total of 190 re-entrant corner dominant building models with different shapes (C-, L-, T-, and PLUS-type), heights, and floor configurations were prepared, and eigenvalue analysis (EVA) was conducted. The fundamental natural period of oscillation for each model was evaluated and compared with the height-based formulas from seismic design codes and the period–height relationship proposed in existing literature. A nonlinear regression model, using a multi-variable power function, is proposed to estimate the fundamental natural period for these re-entrant corner dominant building models. This model considers the A/L ratio in both directions of the building, along with its height. Both unconstrained and constrained regression analyses were performed to derive a formula that best fits the fundamental natural period data. The study recommends that the unconstrained best-fit minus one standard deviation curve can conservatively define the fundamental natural period of oscillation for re-entrant corner dominant RC building models. The equation defining this curve has the potential to replace the existing seismic design code-based period-height formula.

Abstract

Reinforced Concrete (RC) building stocks with plan and/or vertical irregularities are built routinely world-wide, despite being vulnerable to seismic forces. Irregular RC buildings with asymmetry, mass and stiffness irregularities have been well researched, however, seismic behaviour of RC building with re-entrant corner type plan irregularity is given relatively less attention. In the present study, a total of 104 re-entrant corner dominant plan irregular RC building models (C-, L-, T- and PLUS-shaped) are developed along with one regular rectangular building. Plan Irregularity Descriptors (PIDs) are summarized with their limit of regularity and are evaluated for building models. Building models have uni-directional and bi-directional re-entrant corner of 𝐴/𝐿 ratio ranging between 0.1 to 0.8 in the X-direction and between 0.2 to 0.8 in the Y-direction. Seismic response quantities; peak displacement, peak storey drift, normalized base shear and normalized overturning moments are evaluated using the equivalent static method and response spectrum method specified by the Indian seismic code. It has been found that building models yield amplified peak displacement responses in the direction perpendicular to that of applied seismic forces. Other seismic response parameters for all re-entrant RC building models fall well within code based permissible limits. 𝐴/𝐿 ratio limit specified by the Indian seismic code is found to be conservative. Out of various building models considered, C-shaped building models perform well under seismic forces, while PLUS-, L- and T-shaped RC building models with 𝐴/𝐿 ratio ≥ 0.4, in both directions, overshoot torsional irregularity descriptor, ∆𝑚𝑎𝑥 ∆𝑎𝑣𝑔 .

Abstract

Reinforced Concrete (RC) buildings with irregularities, plan and vertical, are susceptible to seismic damage. Such buildings are constructed due to functional, space and aesthetic considerations. Most practical irregular RC buildings have coupled irregularities: plan or vertical or mixed. The seismic behavior of coupled irregular RC buildings is an active area of research. In the present paper, five RC building models with coupled reentrant corners and vertical geometric irregularities are developed along with the regular RC building model. L-shaped and stepped-shaped reentrant corners type plan irregularity is coupled with vertical geometric irregularity by changing plan dimension at each floor level of RC building models. Building models are analyzed for seismic forces following the Indian seismic design code. Seismic parameters-peak base shear, peak displacement, peak interstory drift ratio, modal analysis, normalized base shear and normalized overturning moment-are extracted. It is found that peak displacement and peak interstory drift ratio of coupled irregular building models shows a substantial increase vis-a-vis regular building models. Normalized base shear and normalized overturning moment increase for all coupled irregular building models, except building model BM-3, as compared to the regular building model.

Abstract

The assessment of soil erosion holds paramount significance in sustainable land management and environmental conservation. In this context, the integration of advanced technologies such as the Revised Universal Soil Loss Equation (RUSLE), Google Earth Engine (GEE), and geospatial techniques presents a formidable approach for evaluating soil erosion dynamics. This integrated methodology proves particularly valuable when applied to the Rel River watershed, where factors such as terrain, land use, and precipitation patterns intricately influence erosion processes. The collective use of two methods, the quantitative method focused on RUSLE to assess soil under various circumstances of erosion and sediment yield, whereas the qualitative approach focused on spectral indices of soil erosion in GEE to generate degradation map. This study was aimed at evaluating soil erosion and land degradation across the Rel River watershed in the western region of Gujarat, India. Soil loss has been estimated using soil loss models, i.e., RUSLE and geoinformation datasets, which were extracted from GEE. The degraded area was prepared using GEE and mapped using geographical information system (GIS). The results demonstrate that estimated value for erosion due to rainfall is 37 to 40 MJ mm h−1 ha−1 year−1, soil erodibility is 0.01 to 0.05 ton h MJ−1 mm−1, topographic variables lies in a range from 0 to 20, and crop management factor is 0.001 to 1. The findings also demonstrate that the total annual soil loss for flood events in 2017 is 35.36 t/ha/year, which is categorized into the severe zone of degradation. According to the soil degradation map created using GEE, the majority of the study region falls into the low and medium degradation zones, while the northeastern part and river fall into the high degradation zone. The findings will be helpful in implementing soil management and conservation techniques to arrest soil erosion in the Rel River watershed.

Abstract

Financial ratio analysis has been instrumental over the years to evaluate the financial state of construction companies. However, such an analysis is tedious owing to the presence of a large number of financial ratios corresponding to different construction companies. Therefore, the purpose of this study is to identify the significant financial performance factors (SFPFs) for construction companies. A stratified sampling technique was adopted and the list of companies pertaining to the construction industry was prepared on the basis of scope, sub-sectors, age, enlistment at the national stock exchange, and most importantly the availability of financial statements for last ten years. The data pertaining to financial statements for last 10 years was collected from Capitaline database. In this study, a mixed approach (qualitative and quantitative) has been used involving factor analysis on financial ratios of 100 Indian construction companies over the period of ten years (2008–17) for determining the key factors which govern the financial performance of the companies. A total of five SFPFs were identified, namely investor return, business efficiency, operations management, activity efficiency and risk coverage, and asset management. Further, relative importance of each of these factors was determined by means of percentage explanation of variance respectively. These SFPFs can provide important relevant information about the financial performance of the company. This will help the company and its related stakeholders in better planning of its strategies and policies by focusing on a few important areas for overall improvement of the company. This may further lead to develop a financial performance evaluation framework to evaluate and improve financial performance of construction companies.

Abstract

The construction sector is a major contributor to economic activities in a developing country like India. Hence, it becomes inevitable to continuously monitor performance of the Indian construction companies to take adequate steps for their improvement. This study aims to develop a financial performance evaluation framework (FPEF) for construction companies based on the financial factors derived in the previous study, such as investor return, business efficiency, and operations management. A stratified sampling technique was adopted to select a sample of 100 Indian construction companies based on scope, sub-sectors, age, enlistment at the national stock exchange, and the availability of data of 20 financial ratios for each company in Capitaline database from 2008–17, which translated to a set of 1000 data records. Multi-Attribute Decision Making methods like Shannon-Weaver entropy and Simple Additive Weighting have been used to achieve the objective. As a result, the net financial performance score and performance grade of each company were determined to rank and designate them into five categories for assigning recommendations for improvement. The developed FPEF, including the financial performance equation, will help the concerned stakeholders to take adequate steps for improvement by providing company’s financial trends with respect to time without adopting cumbersome methodology.

Abstract

Despite globalisation bringing diverse opportunities for construction firms from developing countries, executing international construction projects entails many risks. Several past studies illustrate the risks faced by firms in international construction projects and recommend various risk mitigation measures without revealing their effect on project success criteria. In order to fill this knowledge gap, this study aims to test the influence of identified risk mitigation measures on project success criteria. To achieve this, nine risk mitigation measures and three project success criteria—cost performance, schedule performance and firm’s performance—were identified through a literature review. After verifying the identified risk mitigation measures and project success criteria with a preliminary study, a questionnaire was administered to experts who possess adequate knowledge in international construction projects. The collected data from 105 questionnaires were analyzed, grouped and modelled using factor analysis and structural equation modelling (SEM). Application of factor analysis to identify the correlated risk mitigation measures extracted three risk mitigation factors, namely pre-project planning, local participation and contract selection. Furthermore, the influence of risk mitigation factors on project success criteria is hypothesized and tested using SEM. Amongst the identified risk mitigation factors, local participation emerges as the most influencing factor on project success criteria followed by contract selection and pre-project planning. The generated model would enable construction firms from India and similar developing countries to focus on identified risk mitigation factors to achieve improved project success criteria and project management success.

Abstract

Purpose The study of the success factors of a project is a means of improving the effectiveness of the project. Hence, the purpose of this paper is to identify various determinants and validate their effects on the success of public construction projects in Ethiopia. Design/methodology/approach The study uses a questionnaire survey to collect data and structural equation modeling (SEM) to empirically examine the effect of determinants, namely, project manager’s competence, owner’s competence, management support and updates, scope clarity (SC), effective partnering, and monitoring and feedback on success of public construction projects which has been measured by performance on cost, schedule, quality and no-dispute parameters. Out of 407 questionnaires distributed among the selected respondents, a total of 200 completed questionnaires were received. The response rate was 49.1 percent. Findings The results depict that the investigated factors have a significant positive influence on the success of public construction projects with path coefficient of 0.82, the model is substantial in representing the relationship of the factors on the success of public construction projects and the factor “SC” plays a decisive role in the success of a project as it has a path coefficient of 0.98, and it is followed by “effective partnership, and owner’s competency” having equal path coefficients of 0.96. Research limitations/implications The proposed model was validated by collecting data from many senior construction executives in Ethiopia only, hence may induce certain bias in the outcome of the study. Practical implications The significance of six constructs is highlighted to help the project manager in understanding the role of various constructs in public construction projects. The results would enable researchers and industry practitioners to focus on a few factors to take proactive measures and get the optimum result in the successful delivery of public construction projects. Utilization of SEM in the understanding of the significance of various success determinants is an important contribution to the body of theoretical literature in construction management. Since the model includes constructs, SEM has been used for construct validation. Social implications The implications of this study are not limited to researchers and construction industry practitioners alone. The Ethiopian Government could adopt the results of this study to reduce/avoid additional cost incurred due to the poor performance of public construction projects which results in poor utilization and increased social and economic costs. Furthermore, the study may also help the government efforts to enhance efficiency and effectiveness in the use of public funds for construction projects which are an ongoing concern of government and of the international development community. Originality/value This work is original and has neither been published nor under consideration for publication elsewhere. This study can add value to the construction professional in public construction project management as well as the Government of Ethiopia.

Abstract

Purpose – The purpose of this paper is to develop a qualitative framework for the selection of the most appropriate optimization algorithm for the multi-objective trade-off problem (MOTP) in construction projects based on the predefined performance parameters. Design/methodology/approach – A total of 6 optimization algorithms and 13 performance parameters were identified through literature review. The experts were asked to indicate their preferences between each pair of optimization algorithms and performance parameters. A multi-criteria decision-making tool, namely, consistent fuzzy preference relation was applied to analyze the responses of the experts. The results from the analysis were applied to evaluate their relative weights which were used to provide a ranking to the algorithms. Findings – This study provided a qualitative framework which can be used to identify the most appropriate optimization algorithm for the MOTP beforehand. The outcome suggested that non-dominated sorting genetic algorithm (NSGA) was the most appropriate algorithm whereas linear programming was found to be the least appropriate for MOTPs. Originality/value – The devised framework may provide a useful insight for the construction practitioners to choose an effective optimization algorithm tool for preparing an efficient project schedule aiming toward the desired optimal improvement in achieving the various objectives. Identification of the absolute best optimization algorithm is very difficult to attain due to various problems such as the inherent complexities and intricacies of the algorithm and different class of problems. However, the devised framework offers a primary insight into the selection of the most appropriate alternative among the available algorithms.

Abstract

Evaluating the performance of construction organizations is of vital importance for their continuous improvement and long-term survival. Performance measurement enables organizations to compare their performance with that of others to remain competitive in the business. Consequently, identification and evaluation of relevant performance measurement factors is an important research agenda. Although performance measurement at the level of projects has been studied in depth, it has not been investigated properly at the level of organization. In an earlier study , the authors had identified 20 performance attributes based on existing literature and grouped them under six performance factors (PFs): profitability and asset management; satisfaction of key stakeholders; predictability of cost and time; environment, health and safety (EHS); quality consciousness and staff turnover. The present study uses consistent fuzzy preference relation (CFPR) to determine the relative weights of these factors and associated performance measurement attributes. The findings indicate that the satisfaction of the key stakeholders is the most important performance measurement factor whereas, staff turnover is the least important factor for performance evaluation. Based on the findings, a user-interface in the form of a user-friendly software has been developed. The interface will help construction organizations in assessing and improving their performance to remain competitive in a highly competitive business environment.

Abstract

Traditionally, construction organizations with a track record of successful project completion were considered successful construction organizations. However, if construction projects were successful, then it is not always necessary for the construction organization to also have been successful. They can even fail and go bankrupt. Therefore, there is a need to think about the success of construction organizations at a corporate level rather than focusing only at the project level. The objective of this study was to identify and to evaluate the successful attributes for construction organizations. The research methodology involved seeking responses from experts in the construction industry through a questionnaire survey. This paper presents the factors that contributed to the success of construction organizations that operate in the National Capital Region of Delhi, India. Factor analysis of responses extracted eight critical success factors: experience and performance, top management's competence, project factor, supply chain and leadership, availability of resources and information flow, effective cost control measures, favorable market and marketing team, and availability of qualified staff. The top management's competence emerged as the most critical success factor against various performance factors. The success factors that were identified in this study should provide a guideline to construction organizations for their success.

Abstract

Purpose – The purpose of this paper is to evaluate and rank the success attributes and success factors of the construction organizations. Design/methodology/approach – The viewpoints of the experts engaged in Indian construction industry were used to apply factor analysis and fuzzy preference relation with the help of a questionnaire survey. Findings – The findings indicate that project factor is the most important factor, whereas favorable market and marketing team is the least important factor. Among the success attributes, the availability of qualified staff is the most important attribute, and health and safety management plan is the least important attribute. Research limitations/implications – Findings of this study are based on the viewpoint of the experts of construction organizations engaged in building projects in India. Practical implications – The study can be used as a yardstick for the top management of construction organizations to manage their resources efficiently and to develop a strategy to be successful in this business. Social implications – Indian construction industry provides direct and indirect employment to the people of India. Hence, the success of construction organization will contribute to the development of the society and ultimately the nation. Originality/value – In the earlier studies, researchers have used various statistical tools to identify and evaluate the alternatives for the success factors of construction organizations, but very few of them have tried to assign weights to those alternatives. The simple ranking of alternatives using various statistical analyses, such as mean and standard deviation, relative importance index, etc., is not much useful unless their relative weights are known. With the help of the present study, the authors have tried to overcome the shortcomings of the previous research works.

Abstract

Like any other organization, it has become essential for the organizations in the construction industry to measure their performance effectively for long-term survival in today’s competitive business environment. Therefore, it is imperative for a construction organization to know about various performance measurement factors to evaluate its performance. However, most of the previous studies have focused on identification of factors for measuring performance at the level of projects only. Moreover, the majority of these studies have been undertaken in context to the developed construction markets. The present study addresses these gaps in the literature by identifying critical factors for examining the performance of construction firms at the organizational level. A total of 20 organizational performance attributes were identified and analyzed using a questionnaire survey conducted on 106 respondents among 90 different organizations operating in the National Capital Region (NCR) of India. It was found that attributes such as timely completion, relationship with the client, and satisfaction (in terms of both product and services) carry more weight than the cost performance of a construction organization. In addition to this, factor analysis conducted on the performance attributes of high importance has resulted in six performance factors: (1) profitability and asset management, (2) satisfaction of key stakeholders, (3) predictability of time and cost, (4) environment, health, and safety (EHS), (5) quality consciousness, and (6) low staff turnover. The performance factors obtained from the study may provide useful guidelines to the construction organizations enabling them to examine and improve their performance.

Abstract

Ensuring success in the construction business is the aim of the owner/top management of the construction organizations. Previous research indicates that the presence of certain factors in an organization make it more successful compared with the organizations without those factors. Because the construction business is one of the riskiest businesses in the world, identification of such factors and adoption of these factors in the work ethic of the company is of vital importance for the owner/top management of the construction organizations. This study aims to test the hypothesis that success factors influence the success of the construction organization and also explores the impact of these factors on the success of the construction organization. The research methodology involved seeks responses from experts in the construction industry through a questionnaire survey. A total of 106 industry experts from 90 different construction organizations operating in India participated in the survey. Structural equation modeling (SEM) was used to test the hypothesized positive relationships between six success factors, and the success of the construction organization is measured against five performance factors. The findings of the study indicate that top management competence is the most important factor followed by “experience and performance.” The study could provide an excellent value addition to the professionals working in the field of construction management. Further, the results would enable professionals to focus on fewer factors rather than attending numerous factors for optimum result.

Abstract

Because of stiff competition in the construction business, it is necessary for construction companies to measure their performance on a regular interval for long-term survival. Therefore, it is imperative for construction companies to determine the parameters critical to the measurement of their performance. This study identifies the performance indicators, financial as well as non-financial, for construction companies to measure their performance. In a previous study, the authors identified a total of 20 performance attributes and applied principal component analysis which extracted six components called performance indicators. These performance indicators are profitability and asset management; key stakeholders’ satisfaction; time and cost predictability; environment, health, and safety; quality consciousness; and employee turnover. The present study utilized structural equation modelling (SEM) to determine the criticality of these performance indicators for which a questionnaire survey and structured interview approach were adopted. A total of 106 responses were collected from 90 different construction companies operating in various parts of India. The findings indicate that ‘quality consciousness’ is the most critical performance indicator whereas the ‘employee turnover’ is the least critical performance indicator in measuring the performance of a construction company. The performance indicators obtained from this study may help construction companies to measure and compare their performances with their competitors and setting out a strategy to remain competitive in the market.

Abstract

This study presents a methodology for evaluating the walkability of roads within a market area using Multi-Attribute Decision-Making (MADM) techniques. The methodology was applied to rank various roads of the market area based on the existing condition of the pedestrian-built environment in Aminabad market, Lucknow, India. A set of 7 key attributes containing 28 sub-attributes were identified that influence pedestrian safety and mobility. Videography and photographic surveys were conducted at the market roads to gather data, and attribute weights were calculated using the Entropy Weight Method (EWM). The roads were then ranked using Grey Relational Analysis (GRA) and Complex Proportional Assessment (COPRAS). The results showed a strong correlation of 0.896 between the rankings obtained using the two methods, indicating the robustness of the methodology. The study identified several key roads of the market area that were in need of improvement to enhance the overall quality of the pedestrian-built environment. The methodology developed in this study provides a valuable tool for decision-making regarding pedestrian infrastructure improvement in developing countries and is expected to contribute to a safer and more efficient environment for pedestrian movement.

Abstract

Understanding the hydromechanical characteristics of compacted soils is essential as these soils are commonly encountered in several geotechnical structures. The present experimental study evaluated the effect of suction and saturation on the shear and volumetric deformation characteristics of compacted high-plasticity clay. The soil suction values were obtained using filter paper and chilled-mirror hygrometer tests, and small (< 0.001%) to large (> 0.1%) strain dynamic responses were analyzed using a series of bender element and cyclic simple shear tests. Additionally, the volumetric deformation characteristics were evaluated using swell pressure and double oedometer tests. Experiments were conducted on the compacted specimens of Nagpur cohesive soil with varying degrees of saturation (10–95%) and matric suction values (ranging from 52 to 97,930 kPa). The shear strength under static loading increased from 182 to 389 kPa, the stiffness under large-strain dynamic loading increased from 5492 to 10,245 kPa, and collapse potential increased by almost 16 times with the decrease in as-compacted degree of saturation to 50%. Afterward, their values decreased with further reduction in saturation. By contrast, the small-strain shear modulus increased from 19.1 to 65.2 MPa and swell pressure increased from 10 to 212 kPa continuously with the increase in initial matric suction and reduction in the degree of saturation. These experimental findings challenge the conventional assumptions regarding unsaturated clays, emphasizing the consideration of compaction state and microstructural arrangements into the analyses of the hydromechanical response of compacted clays.

Abstract

The present paper evaluates the impact of stress history on yielding, shear and energy dissipation response of earthen dam soil under static and cyclic loading conditions by conducting consolidated undrained (CU) triaxial tests and cyclic simple shear (CSS) tests respectively. The current research has been performed at four different stress histories (over consolidation ratio = 1, 2, 5, 10) on loose, medium and very-dense specimens under static and cyclic loading conditions. The generation of stress history enhanced the soil particle interlocking and stability of the soil structure resulting in substantial improvement in the undrained static and cyclic strength of the soil. Loose and medium-dense specimens’ shear response exhibited metastable structure formation; conversely, the very-dense specimens revealed more stable structural adjustments. The ‘teardrop’ shaped yield surface grew substantially as the density state changed from loose to medium-dense to very-dense. The incremental strain vectors at pre and post-instability states indicated highly compressive behaviour in loose and medium-dense specimens. The undrained static and cyclic shear behaviours were analysed in the context of energy dissipation under different stress histories. All soil specimens (loose to very dense) exhibited liquefaction susceptibility under cyclic loading conditions at all stress histories.

Abstract

This experimental study focused on cyclic degradation and cyclic pore-water pressure response of high-plasticity compacted clay under different dynamic loading and initial static shear stress conditions. The strain-controlled undrained cyclic simple shear tests were performed at different initial static shear stress ratios (τs/Su=0, 0.45, 0.65, 0.79, and 0.87), cyclic strain amplitudes (γc=0.5%, 1.5%, 2.5%, and 3.75%), and frequencies (f=0.1, 0.5, 1, and 2 Hz). The results revealed that the initial static shear stress significantly increased the magnitude and rate of stiffness degradation and cyclic pore-water pressure generation. The mobilized shear stress under cyclic loading decreased below the static shear strength within only five loading cycles. The shear modulus increased and the damping ratio decreased with the increase in frequency and decrease in cyclic strain amplitude. The enhanced rate of stiffness degradation followed a power-law functional relationship with cyclic strain amplitude, and its trend was dependent on the magnitude of the initial static shear stress ratio and the cyclic strain-reversal conditions. The experimental results clearly demonstrated the coupling between cyclic degradation and pore-water pressure generation. A strain-based model was formulated for the risk assessment of compacted high-plasticity clay (CH soil) subjected to combined static and cyclic loading.

Abstract

This experimental study investigates the effect of K0, anisotropic and isotropic consolidation stress paths on the undrained mechanical response of compacted high plasticity clay. This type of soils is being used for the construction of the core structure in the earthen embankment dams. Therefore, undrained soil properties in saturated state are essential to obtain for the stability analysis and design of certain conditions, such as rapid drawdown case. The actual consolidation system prevailing in the field is anisotropic in nature, and it is necessary to take that into account for the determination of strength and yielding criteria of the soil. However, this effect of the consolidation system has not been studied in detail for high plasticity clay in a compacted state. A series of consolidated undrained triaxial compression and extension tests were carried out on compacted high plasticity clay with different consolidation stress ratios (Kc = σh′/σv′  = 0.70 to 1.00) and stress history (OCR = 1 to 10). Results indicated that the normalized undrained shear strength reduced with anisotropic consolidation, and its relationship with consolidation stress ratio (Kc) was found linear at each OCR levels. The reduction in strength was observed highest for extension loading condition at normally consolidated state. Strain energy dissipation response displayed that the governing strain energy mechanism shifted from volumetric to shear strain energy, as consolidation state changed from anisotropic to isotropic. Based on the obtained yield surfaces, pre-failure shear behaviour of soil was found predominantly elastic for compression loading and elasto-plastic for extension loading conditions.

Abstract

This experimental study describes the elastic and yielding response of compacted high-plasticity clay in conjunction with deformation characteristics at relatively larger strains for different stress paths and stress states. K0 consolidated undrained triaxial compression and extension stress path tests were conducted on compacted Nagpur cohesive soil with bender element measurements to explore the elastic and yielding response of soil. The experimental results showed that the stress path direction had a significant impact on the stress–strain–strength properties of soil as the peak deviatoric stress was found to increase with the increase in stress path angle. The measured small-strain shear modulus (Gmax) values were observed to be a function of the mean effective stress (p′) with slight dependency on deviatoric stress (q). Gmax was found to reduce with increase in strain level during shearing. An attempt was made to formulate an empirical correlation for compacted cohesive soil based on the elastic shear stiffness in pre-yield conditions. This correlation was further used to determine the yielding criteria of compacted cohesive soil along with the other two well-established criteria of stress–strain and strain energy.

Abstract

Prolonged and repeated drought, as seen in India and other parts of South Asia, is a symptom of climate change, which is partially the result of human interventions. The performance of the widely used drought metrics Standardized Precipitation Index (SPI) and Standardized Precipitation Evapotranspiration Index (SPEI) are evaluated for 18 stations in Uttar Pradesh state for the period 1971 to 2018 in this study. Drought characteristics such as intensity, duration, and frequency of different categories are estimated and compared based on SPI and SPEI. In addition, station proportion is estimated at a different timescales, providing a better insight into temporal variability drought of a specific category. Spatiotemporal trend variability of SPEI and SPI was investigated at a significance level of 0.05 using the non-parametric Mann–Kendall (MK) test. SPEI adds the effect of temperature rise and deficit change on the drought occurrences of different classes. SPEI provides a better estimation of drought characteristics due to its consideration of temperature change in the drought severity. The more significant number of drying events accounted for a timescale of 3 months and 6 months, reflecting the higher variability of the seasonal fluctuation of water balance over the state. At 9-month and 12-month timescales, SPI and SPEI fluctuate gradually with considerable differences between the duration and severity of the drought event. This study reveals that there have been a substantial number of drought events over the state during the last two decades (2000 to 2018). The results conclude that the study area is at risk of erratic meteorological drought conditions where the western part of the study is worst affected compared to the eastern part of Uttar Pradesh (India).

Abstract

Climate change is the most considerable peril to the environment and a significant concern for humans of twenty-first century, which affects life all around the globe. River Ganges basin is highly vulnerable to climate change, which plays a vital role in socio-economic activities and the water supply for livelihood and irrigation in the northern part of India. A statistical downscaling model (SDSM) is used to forecast future changes in the maximum temperature of the Ganges basin (India) due to climate change under the 2.6, 4.5, and 8.5 RCPs scenarios of the CanESM2 model outputs for the forthcoming annual change (2006–2099) as well as monthly changes in maximum temperatures. In addition to that, the use of 26 large-scale climatic variables that were produced using data from the NCEP reanalysis (1961–2005) and the Canadian Earth System Model (CanESM2, 1961–2100) is employed. It is critical to identify the best predictors to use for the simulation phase for each location using SDSM. The investigation revealed that there was an increase of between 0.4 and 3.4 °C in the maximum average temperature over the basin at study stations. Furthermore, according to the RCP 8.5 scenario of the CanESM2 model, these maximum temperature changes will be raised to a greater extent than under the RCP 2.6 and RCP 4.5 circumstances. The months of March–July were predicted to have significant raise temperature (maximum) in all scenarios and the least variation in maximum temperature projection during August and September. According to an uncertainty analysis linked to model scenarios, the CanESM2 model under scenario RCP 4.5 performed the best in the simulation of future maximum temperatures of all scenarios. The downscaled data provide better management of projected temperature and, ultimately finer scale adaptation plans in the basin.

Abstract

Climate variability has received a great deal of attention worldwide; thus, the current research focuses on the trend of precipitation and temperature over Patna districts of Bihar from 1901 to 2002. Nonparametric methods, Mann-Kendall (ZMK), Sen's slope estimator (Mi), and linear regression analysis were used to analyze the trend and its magnitude. Annual and monsoon rainfall demonstrate a significant declining trend, whereas winter and premonsoon showed an insignificant declining trend, and postmonsoon showed the inclining trend. Furthermore, the slopes of the regression lines for minimum temperature and average temperature illustrate a positive trend with slope value 0.0063 and 0.0043, respectively, whereas the maximum temperature shows a negative trend with slope value − 0.0031, ZMK, and Mi the negative trend with − 0.5204 and − 0.0081, respectively. Thus, the findings show that the probability of severe climatic events in the Patna district is rising, increasing people's vulnerability and having significant policy consequences.

Abstract

Municipal Solid Waste Management (MSWM) is essential as it impacts health, the environment, and aesthetic society if it is not managed correctly. Hence improving the quality and standard of living. There is an urgent requirement to neutralize the waste and the best possible solution for organic waste. It can be used to generate biofuels and utilized to generate electricity. The production of energy from waste depends on organic waste, so the energy potential of Bhopal city has been categorized into different sectors such as Urban Organic Solid Waste (UOSW), Pulp & Paper, Cattle, and Poultry, in which UOSW is 42% and, the Urban Organic Liquid Waste (UOLW) 25%, Cattle 23%, Poultry 2% and Pulp & Paper 8%. The UOSW has been analysed, and it has been categorized in Slaug (1%), Organic Solid waste (33%), Poultry (3%), and Cattle (63%), and the UOLW in Slaug (1%), UOLW (98.9%), and paper and pulp (0.10%). Total waste generated in Bhopal per day is 1123 TPD of which, 54.3% is organic waste that we can use to generate biofuel, i.e., 609 TPD, which can generate 165MW energy per day.

Abstract

The environmental concerns associated with the use of portland cement prompted finding an alternative. As a possible solution to this issue, fly ash–based geopolymer concrete has been developed and implemented in roller-compacted concrete pavement. The mechanical and rheological properties of roller-compacted geopolymer concrete were analyzed, accompanied by the chemical characterization through X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDXS) of the optimized samples, which confirmed the formation of geopolymer. The research entailed creating a stepwise mix design to determine the aggregate proportion and particle-size distribution of mixed aggregate that can achieve high packing density, resulting in improved roller-compacted geopolymer concrete properties. The optimized mixture was developed using dry sodium hydroxide (NaOH) to produce roller-compacted concrete, and the mixture characteristics were analyzed in different weather conditions such as humidity and temperature. The compressive strength after 28 days was 58 MPa at ambient curing and 61 MPa at thermal curing conditions. Flexural strength and split tensile strength were 5.5 and 4.2 MPa, and the modulus of elasticity was 33.10 GPa. The designed concrete was tested in the field by filling patches on cement concrete and bituminous pavements and compacting them with a prototype roller developed to test the mutual adhesiveness of the concrete and roller.

Abstract

Bundelkhand region is highly susceptible to meteorological and hydrological droughts, because of the reduced rainfall due to climate change and higher water demand for agriculture. The temporal and spatial drought characteristics of the Bundelkhand region were estimated by the standardized precipitation index (SPI) for the period 1961–2016. Non-parametric statistical tests including, the Mann-Kendall (MK) and Spearman’s rho (SR) have been used in precipitation and SPI series to detect monotonic trends. Statistical tests showed a significant decreasing trend for annual rainfall data with ZMK statistic ranges from −3.93 to −5.54 and ZSR statistics from −4.42 to −7.17 at 5% significant level. Additionally, the magnitude of trend was estimated by using Sen’s slope estimator and the Mi values range from −9.72 to −17.33 which define the extreme condition of drought. Linear regression analysis for monsoon months and annual precipitation also shows the negative slope value, indicating a considerably decreasing trend. Variable-sized cluster analysis (VSCA) provides a visible picture of the irregular rainfall pattern and has been employed for 3-D characterization of rainfall trends and their change point. Trend analysis of SPI on different timescale revealed a negative trend and that negative trend increases with increasing timescale. The highest ranges of drought index indicate the severe to extreme drought category for the study area. The significant drought event with high intensity occurred in 1966, 1987–1990, 1993–1995, 2002, 2007, 2011, and 2015.

Abstract

Time-series data for climatic variables of Jharkhand state, India were analyzed to assess the spatio-temporal variation and fluctuation over the study period of 118 years (1901–2018). Mann–Kendall (MK), Sequential Mann–Kendall (SQMK), and Sen’s slope tests were applied to determine the trend of precipitation, temperature maxima–minima, and Potential Evapotranspiration (PET) time-series data acquired after removal of serial autocorrelation called prewhitening. Minimum and maximum temperature revealed insignificant variation during pre-monsoon and monsoon season, while a remarkable increasing trend was observed for post-monsoon and winter season; however, increasing trend was obtained for annual maxima–minima. The average minimum temperature fluctuates with an increase of 0.59–0.41 ºC to a decrease of 0.79–0.39 ºC, whereas average maximum temperature fluctuates with an increase of 1–1.5 ºC to decrease of 0.82–0.14 ºC. Notably, decreasing trend of 1.09–2.3 mm/year was observed for precipitation during monsoon season, whereas decreasing trend of 1.2–2.4 mm/year was found for annual precipitation, and similarly for PET, significant decreasing trend of 0.0003–0.0012 mm/year was found for monsoon season and annually. However, the underlying persistence effect observed in all seasons and throughout the year for all climatic parameters resulted in the time-series with low-frequency fluctuations. SQMK method exhibits the periodic fluctuation of trends, which are more noticeable in pre-monsoon and monsoon season. An understanding of these alterations in pattern of climatic variables is important for planning and management of water resources and sustainable agriculture.

Abstract

A novel analysis procedure, referred to as variable-sized cluster analysis (VSCA), was developed to identify trends and change points in precipitation time series data set. The procedure involved station-scale rainfall data of 100years from seven districts (Saharanpur, Bareilly, Agra, Jhansi, Lucknow, Varanasi, and Gorakhpur) of the state of Uttar Pradesh (UP), India. In contrast with the traditional Mann-Kendall (MK) test that yields a monotonic trend for the whole span of time, VSCA enables one to detect multiple change points while characterizing the pattern of precipitation trends over the historical time period. The Pettitt-Mann-Whitney (PMW) test was also modified to graphically represent the multiple change points, which confirmed the results of VSCA. Thus, VSCA demonstrated the unified strength of MK and PMW tests. The three-dimensional (3D) figures drawn for visualizing the changing trend of precipitation utilized 100-year-long time series data set with the minimum size of data cluster as 10, which resulted in the right triangular shape of the graphs due to the repeated application of the MK test to variable-sized data clusters. Application of VSCA showed a decreasing trend of precipitation over Lucknow, Gorakhpur, and Varanasi around 1990 onward, with major changes in the decades of 1970–1980. Saharanpur and Agra contrarily displayed an increasing trend until 1940 and no trend thereafter; however, Bareilly and Jhansi showed reducing trends in precipitation.

Abstract

The Road Infrastructure is the backbone of the development of the country. A superior quality of road infrastructure has the potential to boost the coun-try’s economy. The roads deteriorate over time due to wear and tear and weather conditions. The pavement condition assessment should be addressed in the early stage of failure of the road to maintain serviceability and avoid further deterioration. At present, the traditional road assessment method is being used in practice. This road condition assessment method is labour-intensive, time-consuming and expensive. Remote sensing technology is proven efficient when a large area is required to be observed. It is quick and inexpensive compared to in situ measurements. Remote sensing techniques allow frequent, comprehensive, and quantitative surveys of road infrastruc-ture. Hyperspectral Remote Sensing imagery utilises many narrow contiguous spectral bands together with detailed spectral information, often regarding chemical and mineral properties of observed features. The reliability of hy-perspectral imagery greatly depends on the field data collection. To validate Hyperspectral Remote imagery results, field spectrometer data are widely used. In the present project, the use of Hyperspectral imagery is proposed to study road material identification and distress analysis. As a pilot project, the field spectra of Concrete and Bitumen Roads were collected with a high-resolution field portable spectroradiometer SVC HR-1024 to study the spec-tra of bitumen and concrete material. It collects the spectra in the range of 350 nm to 2500 nm spectral range. It can discriminate minor spectral varia-tions for roads with different ages and conditions. The results of the field spectrometer are thoroughly studied before using Hyperspectral imagery and presented in this paper. Keywords: Hyperspectral Remote Sensing, Road Condition Assessment, Field Spectrometer.

Abstract

Satellite Navigation System is a constellation of satellites that transmits signals from space to help users determine their position with time. The Indian Space Research Organization created the regional navigation satellite system, the Indian Regional Navigation Satellite System (IRNSS). High positioning accuracy is needed to integrate the usage of IRNSS over various positioning systems, which necessitates modelling each bias. This research aims to model the tropospheric bias that retards the IRNSS transmissions. Weather-related variables can be used to model this systemic bias. However, the physical characteristics and climate of the Indian continent set it apart from other parts of the world. Thus, to incorporate local climatic conditions regional tropospheric model is highly essential. We have used the saastamoinen model to model tropospheric delay and then compared it to the receiver-generated delay. The results show that the tropospheric delay ranges from 2 to 8 m based on the zenith angle and other meteorological parameters. It shows a similar tendency to the receiver-generated delay. Further, a high correlation between the zenith angle and tropospheric delay indicates that the delay can be molded as a function of the zenith angle. The correlation is the same for all geosynchronous satellites and can be described as a function of a two-degree polynomial (R2 > 0.99). However, the tropospheric delay of geostationary satellites I03 and I06 correlate less with the zenith angle.

Abstract

Sun Induced Fluorescence (SIF) serves as useful means for detecting the condition of vegetation as it has a close correlation with photosynthesis, thus it is used to derive Gross Primary Product (GPP). SIF could be a good estimator of net photosynthesis levels in crops affected by water deficit and nutritional stress. The field collected spectral signatures of wheat crop are used of different growth stages under control and stress treatments. SIF retrieval for wheat crop is done from spectral reflectance signatures using Spectral Fitting Method (SFM). Relations between SIF signals and key photosynthetic parameters from combined gas exchange and chlorophyll fluorescence at leaf level based on Farquhar–von Caemmerer–Berry leaf photosynthesis model fitting and others. Analysis is done for observed patterns of relationships and thus contributes to the understanding of usefulness of SIF as crucial for remote sensing application.

Monitoring continuous crop growth and health under various conditions at different spatio-temporal resolutions is a key to assess yield stability, crop diversity, adaptability, mitigation for stress and response. The quantification of crop biophysical and biochemical variables spatially from remotely sensed data with help of spectroscopic methods provide a reliable discerning information in the context of crop foliar condition like leaf greenness, senescence, canopy density, crop growth, stress and eco-physiological processes. Airborne Visible/Infrared Imaging Spectrometer-Next Generation (AVIRIS-NG) airborne hyperspectral data offers high spatial and spectral resolution giving a unique advantage and opportunity to test retrievals of crop biophysical (BP)-biochemical (BC) variables under varying conditions over different types of crops. A hybrid inversion of leaf-canopy Radiative Transfer model – PROSAIL-D complemented with use of data driven nonlinear non-parametric methods which offer simplicity, fastness, reliability and competency is a powerful method to retrieve crop biophysical and biochemical variables. The Hyperspectral band (feature) selection is a computationally cost efficient method to overcome data redundancy in high dimensional correlated input spectral bands. The determination of optimum subset or combination of hyperspectral bands specific to retrieval of vegetation properties (including canopy effects) determined using feature selection algorithm for regression-based retrievals are active research topic unlike classification problems in which it is more common. A band selection algorithm based on Gaussian Processes Regression was used to choose most sensitive bands from in-situ biophysical-biochemical measurements and crop spectral signatures collected for analysis in two different agricultural regions: Raichur (Karnataka) and Anand (Gujarat) districts of India representing diverse landscapes, heterogeneous crop canopies and agro climatic settings. The retrieval algorithm for AVIRIS-NG image employed a decision tree ensemble algorithm Canonical Correlation Forests using the optimum subset of bands for retrieval of targeted crop variable. Validation of retrieved crop variables were done using in-situ ground observations collected over heterogeneous diverse crop landscape. The results showed chlorophyll (RMSE = 6.61 µg cm−2), equivalent water thickness (RMSE = 0.002 cm), leaf area index (RMSE = 0.35 m2/m−2) and dry matter (RMSE = 0.003 g cm−2), carotenoid (RMSE = 14.3 µg cm−2), anthocyanin (RMSE = 12.92 µg cm−2) retrieved with better accuracies. The results obtained in context of feature (band) selection approach for Radiative Transfer model inversion show overlapping of sensitive spectral bands of chlorophyll-ab, carotenoid and anthocyanin especially between narrow spectral range 480 to 560 nm as predominant reason for decreased accuracies of anthocyanin and carotenoid compared to other variable. This poses a limitation as well as opportunity for further research in signal separation in context of feature selection approach especially in context of broader spectral bandwidths. It also sets ground for further development of feature selection algorithms that use hybrid regression methods customized for crop specific traits.

Abstract

The construction industry contributes a huge number of employments in India, but despite its economic importance and job creation, it faces challenges such as low productivity, project delays, and a lack of professional practices in the industry. A construction project's time and cost performance are largely determined by Productivity. Although, there have been research which focuses on general productivity, but there is no research done specifically for any particular component. Therefore, the present research work focuses on productivity analysis of column erection activity. Key parameters that hinder the Column Formwork Erection are identified by preparing Work Breakdown Structure (WBS) and identifying factors which lead to preparation of a questionnaire that includes 37 questions. The questionnaire is used to collect data of 97 ongoing construction projects of Gujarat state. The data is used to calculate Relative importance index (Rii) value for severity and occurrence. As the ranking of reasons cannot be singly based either on severity or occurrence, a unique analysis is done by finding the Cumulative value which is a function of both severity and occurrence to rank the reasons. The result reveals the major reasons that affects formwork erection activity are improper planning and scheduling of formwork activities, lack of Finance, design fluctuation, pandemic and availability of labors as well as skilled labors and are discussed in this paper.

Abstract

Net surface radiation (Rn) at earth surface comprises of incoming and outgoing components of shortwave and longwave radiation fluxes at the surface. This influences energy and mass exchange over earth surface at sub-daily, seasonal and annual time scales. This is a critical component for land surface models which characterize climatic, ecological and biological processes. Measured net radiation datasets are rarely available and can be subjected to errors and high uncertainties due to equipment malfunctions and failure. In this study, a regional-scale model is developed and implemented to estimate the net surface radiation fluxes over Indian landmass under cloudless sky conditions using the data from an Indian geostationary (GEO) Meteorological satellite (INSAT 3D) and polar orbiting (LEO) MODIS-Aqua for daytime conditions. The estimated measurements were evaluated over a period of three winter months during January to March, 2020 at three in situ measurement sites, located in cropland and grassland. The results showed a correlation of 0.89 between satellite-based Rn estimates and in situ measurements with a root mean square error (RMSE) of 76.4 Wm-2 (5.3% of measured mean) and a mean average error (MAE) of 8.0% of measured mean. The modelled estimations were compared with NCEP reanalysis global surface radiation estimations over diurnally, the NCEP model tends to under or overestimate during the study time period especially during the months of January.

Abstract

Launch of Sentinel-1B satellite in April, 2016 completed the two satellite Synthetic Aperture Radar (SAR) constellation of European Copernicus Sentinel-1 mission. Calibration of this sensor was executed by European Space Agency during commissioning phase and an independent calibration by German Aerospace Center (DLR) in 2016. To assess the stability of the instrument, monitoring of the calibration parameters is required. This study reports the results of temporal stability assessment of radiometric calibration and image quality parameters of Sentinel-1B SAR data using the Corner Reflector (CR) array, Surat Basin, Australia. Impulse response functions (IRFs) generated from the CRs in the satellite images were used to derive the image quality parameters. The mean deviation of the Radar cross-section (RCS) from the theoretical value (38.40 dBm2) of 1.5m CRs (for all the dates), derived from the images, was found to be 0.53 dBm2, which is as per the absolute radiometric accuracy specified for the Sentinel-1 SAR system. Derived image quality parameters viz. the mean peak to side-lobe ratio (PSLR), mean integrated side-lobe ratio (ISLR), spatial resolutions in the range and azimuth directions were found to be as per the specified value for Sentinel-1 SAR system. The results indicated the good quality of Sentinel-1B data.

Abstract

Estimation of LWin under overcast conditions like fog, has been one of the prime challenges of modelling the radiation budget. This is due to the lack of instrumentation and regular measurements at different space-time scales, especially in tropical and sub-tropical regions. In this study, two Multi-Layer Perceptron (MLP) based Artificial Neural Network (ANN) models were developed for LWin flux estimation under foggy sky during daytime and nightime. The models were developed using half-hourly flux measurements over different agro-climatic settings and several atmospheric parameters, from satellite observations and numerical model outputs. A comparative evaluation was made between Radiative Transfer (RT) computations and ANN-based models. The ANN models were found to have consistent performance across different sites except slightly less accuracy in sub-humid or humid climate. The ANN models showed overall RMSE of 4.4% and 4.6% with correlation coefficient of 0.9 and 0.86 for daytime and nightime, respectively with reference to in situ measurements.

Abstract

Hyperspectral Remote Sensing is a sub-branch of remote sensing, which captures information in contiguous spectral bands over a very narrow wavelength range. Hyperspectral data cube captures a large number of datasets in the form of multiple contiguous bands Data Classification divides the datasets into multiple classes for feature extraction, material identification and temporal change analysis. Selection of proper classification technique is vital for higher accuracy. Single stage classifications sometime cannot extract sub fea- tures within a single class with required accuracy. The current study deploys a multi staged classification approach for the extraction of built up and road material over a study region. The study compares the performance between various classi- fication techniques like Support Vector Machines (SVM), Maximum Likelihood, Minimum Distance and Mahalanobis Distance. Out of all classification techniques, Support Vector Machines provided the highest accuracy of nearly 90% in both the classification stages. First stage classification using SVM delivered 89.3% accuracy and further 2nd stage classification i.e., Material Identification delivered 90.0% accuracy.

Abstract

Net surface radiation defines the availability of radiation energy on and near the surface to drive many physical and physiological processes such as latent heat, sensible heat fluxes, and evapotranspiration. One of the prime challenges of modeling radiation budget is estimation of net longwave radiation. Incoming or downwelling longwave radiation (LWin) flux is one of the two key components of net longwave radiation. Its estimation in cloudy conditions has always been a challenge due to lack of instrumentation and regular measurements at different spatial scales. In this study, two artificial neural network (ANN) multi-layer perceptron (MLP) models were developed for LWin flux estimation under cloudy-sky during daytime and nighttime using half-hourly flux measurements over different agro-climatic settings and several atmospheric parameters from measurements, satellite-based observations, and model outputs. A comparative evaluation was made between existing or newly developed multivariate linear regression (MVR) models and ANN-based models. The latter set of models were found to be superior to the best MVR model during both daytime and nighttime. The ANN models were found to have consistent performance across different sites and cloud types except less accuracy in sub-humid or humid climate and in deep convection cloud. The ANN models showed overall accuracies of 2.7% and 3.3% of measured mean and R2 of 0.86 and 0.85 for daytime and nighttime, respectively, when compared with independent data of in-situ measurements

Abstract

Accessibility Analyst tool of GIS is employed to analyze the optimum accessibility dis-tance to BRT station around its immediate neighborhood. The accessibility to transit net-work is a major issue in the planning of efficient bus transit, which affects the ridership significantly. The present study analyses the catchment area, a distance-decay buffer zone with actual street network and interoperates with GIS spatial data. Three corridors with 27 existing stations, field data was collected, which includes the distance between the sta-tions, intersection distance, walking distance of commuter from different modes, age, gender, type of employment, the purpose of the trip, travel time to reach station and in-come of users. The analysis showed that the station locations is an integral part and result-ing in spatial distributions of accessibility over a neighborhood. A GIS analysis gives an opportunity to BRT operators, commuters and authorities to spatial visualization of com-muter’s accessibility from stations to its neighborhood.

Abstract

In India, the fast-growing cities are facing sedate problems of traffic congestion due to the unprecedented urbanization in the last few decades. To give mobility of high populace density, these cities usually rely on multi-modal transit services, including private and public modes. Public transport plays an important role in building up the transportation structure. Effective implementation of public transport greatly depends on the accessibility of transit station about the urban region. This study presents the approach for the relocation of the transit station based on an evaluation of spatial accessibility to BRT stations in the environment of Geographical Information System (GIS) for Ahmedabad City. In GIS the service area and distance-decay analysis tools were used to find the most appropriate BRT station location. The study was performed on three selected corridors consisting of 27 BRT stations. Field data collected includes distance among the bus stations, distance from bus stations to intersection, on walking distance of commuter to the bus station and commuters’ characteristic like age, gender, type of employment, purpose of trip, mode of travel, time is taken to reach station and income from immediate neighborhood from board and off-board commuters. Analysis showed that relocating BRT station, results increase in the service area and that leads to commuter ridership. It was observed that relocating the station also changed the approachable population densities of the respective station. After relocating the current stations, the population density or commuter ridership increased by average 60% for 0-150 m radius, 150-400 m increased by 35% and 400-600 m increased by an average of 20% with respect to six (6) stations of the three study corridors. This result would help BRTS operators and BRTS operating authorities to take a decision about BRT station location suitability. Thus, it is recommended to consider the population densities and accessibility also t

Abstract

The fundamental natural period of oscillation is a critical parameter in evaluating the design base shear of buildings. Worldwide seismic design codes typically employ height-based empirical formulas to estimate this period for various building categories, without distinguishing between regular and irregular buildings. This study proposes a formula specifically for reinforced concrete (RC) moment-resisting frame (MRF) buildings with dominant re-entrant corner type plan irregularity. A total of 190 re-entrant corner dominant building models with different shapes (C-, L-, T-, and PLUS-type), heights, and floor configurations were prepared, and eigenvalue analysis (EVA) was conducted. The fundamental natural period of oscillation for each model was evaluated and compared with the height-based formulas from seismic design codes and the period–height relationship proposed in existing literature. A nonlinear regression model, using a multi-variable power function, is proposed to estimate the fundamental natural period for these re-entrant corner dominant building models. This model considers the A/L ratio in both directions of the building, along with its height. Both unconstrained and constrained regression analyses were performed to derive a formula that best fits the fundamental natural period data. The study recommends that the unconstrained best-fit minus one standard deviation curve can conservatively define the fundamental natural period of oscillation for re-entrant corner dominant RC building models. The equation defining this curve has the potential to replace the existing seismic design code-based period-height formula.

Abstract

Axial–flexural behaviour of Concrete Filled Steel Tubular (CFST) column specimens utilizing routinely used Indian hollow steel tube sections is investigated. Eighteen test specimens comprising of circular, square and rectangular geometrical shapes are considered. A simple mechanism is developed with pinned end conditions to utilize full testing length of slender CFST column. Maximum load, axial shortening and lateral displacement parameters are evaluated to quantify axial–flexural behaviour of slender CFST column test specimens. Normalized ratios in terms of confinement factor, steel and concrete contribution ratio, ductility index, strength index and load carrying capacity are estimated to study efficacy of geometrical shapes of CFST column test specimens. It has been found that square CFST column outperforms circular and rectangular CFST column for resisting maximum load with global buckling as predominant mode of failure. The maximum load carrying capacity of circular, square and rectangular CFST test specimens under concentric loading is found to reduce for eccentric loading with increased eccentricity. Concentrically loaded CFST column test specimens show local buckling as predominant failure against global buckling failure under eccentric loading. Design code EC4 estimates load and moment for CFST column test specimens in close agreement to experimental values. Dissection of the CFST test specimens reveal that concrete infilled hollow steel tube cracked due to tensile and compressive stresses ensuring perfect bond assumption between steel and concrete elements.

Abstract

Unprestrained NiTinol shape memory alloy wire based tension sling damper, SMA-TSD, is developed to produce passive damper force at ground story of three story modal building. Nonlinear hysteretic behaviour of superelastic SMA is represented by one dimensional Tanaka model. SMA-TSD is characterized by linear Voigt model with equivalent stiffness and equivalent viscous damping components under seismic excitations to implement it with linear modal building. Equivalent viscous damping ratio is evaluated by proposed instantaneous damping approach more appropriately simulating practical scenario as well as constant damping approach used in other studies. Uncontrolled and controlled response of modal building are obtained to prove efficacy of superelastic passive SMA-TSD. Seismic performance indices are found to reduce substantially for controlled modal building when design parameters of passive superelastic SMA-TSD are adjusted.

Abstract

Masonry buildings made from passive stone/brick materials are acceleration sensitive and vulnerable to seismic forces. Current construction practices see a surge in use of light weight Autoclaved Aerated Concrete (AAC) blocks. This paper studies dynamic behavior of semi-engineered AAC block masonry building models under shock loading. Two half-scale models are constructed practicing half-block joint (English bond) and full-block joint (Stretcher bond) on a unique semi-automated shock table facility. Dynamic response of long and short walls of building models are measured with reference to base excitation. Building model built with stretcher bond survives despite suffered with heavy damage and perform better than model with English bond which collapsed under series of shock loading. Long walls of models observe major damage due to out-of-plane bending modes, shear cracks and vertical separation at wall junction. Peak acceleration response of long walls shows reduction with progression of damages with reference to base excitation. Performance of AAC block masonry building is found to be at par with red-clay brick masonry building studied previously.

Abstract

Passive Shape Memory Alloy (SMA) based Tension Sling Damper (TSD) is proposed to control seismic re-sponse of building represented as dynamic SDOF system. Non-linear hysteretic behavior of SMA is character-ized by Tanaka model with seismic excitations as input. It is converted to equivalent piece-wise linear elastic viscous damping model described by stiffness constant ‘keff’ and damping constant ‘ceff’ to implement it with linear dynamic system. Damping constant ‘ceff’ is evaluated for TSD for given seismic excitation at each in-stance of time defined as instantaneous damping, unlike constant damping used in other studies, to derive ac-curate seismic response of the dynamic system. Seismic response control parameters – peak and rms perfor-mance indices (PI) for displacement and acceleration, peak damper force, maximum damping ratio are evalu-ated for flexible, moderately stiff and stiff dynamic systems fitted with TSD under pulse and strong ground motion type seismic excitations with varied PGA. Substantial reduction in PI is observed for controlled sys-tems through varying design parameters of TSD – cross-sectional area and length of SMA sling. TSD yields better seismic response control for moderately stiff and flexible system due to super-elastic properties of SMA. Further, it works efficiently for seismic excitations with low to moderate PGA.

Abstract

Damping ratio is an important and central parameter for the dynamic analysis of structures. The present study focuses on the estimation of the equivalent damping ratio in a post-yield region for RC frames, both with and without infills. One-story one-bay RC frames casted non-integrally with fly ash (FA) bricks and autoclaved aerated concrete (AAC) blocks infills are considered and are tested under monotonic lateral half-cycle loading. Post-yield behavior parameters, displacement ductility and maximum drift ratio, are used to estimate the equivalent damping ratio at each cycle of lateral loading, and empirical relationships are established. Secant stiffness and stiffness degradation for RC frames are also extracted to determine the contribution and effectiveness of type of infills. Free vibration tests on RC frame specimens are conducted subsequent to each cycle of monotonic lateral loading, and the damping ratio is evaluated. It is found that the equivalent damping ratio substantially increases for RC frames with the onset of damage in the post-yield region. The major advantage of the infilled RC frame is a drastic reduction in the maximum drift ratio. However, types of infill are found to yield equivalent damping ratio at par, suggesting similar energy dissipation capabilities. RC frame infilled with AAC block is recommended due to its higher initial as well as secant stiffness vis-a`-vis FA brick-infilled RC frames and higher stiffness degradation that allows it to behave similar to RC frame without infill.

Abstract

Structural elements and systems used in spacecraft and antenna structures are flexible and light in weight. Vibration in flexible structures may produce secondary effects in it and affect the performance. Therefore, it is important to control structural response of flexible structures. This can be achieved by either Passive control or Active control. It has been found that active control of flexible structures may lead to instability, if there is an error in feedback control. In such situations passive control of flexible structures coated with thin viscoelastic material offers promise. Apart, smart materials like Piezoelectric Ceramic Powder, Magnetorheological Fluids etc. are potential alternatives. In present study cantilever structure made up of aluminum material is considered. Bare specimen is coated with Piezoelectric Ceramic Powder. Acceleration is captured using Data Acquisition System and LabVIEW through Free vibration test. Results shows piezoelectric powder coating increases damping into the system.

Abstract

Earthquake is a natural hazard that causes damage or sometimes complete collapse of man-made structures. It is measured as ground excitation with acceleration and time data points measured at various locations through digital instruments. All ground excitations measured do have potential to cause damage to the structures but strong ground motion do. Strong Ground Motion is characterized by various parameters like Peak Ground Acceleration (PGA), Frequency Content, Root Mean Square (RMS) Acceleration, Arias Intensity and Duration of strong ground motion. Strong ground excitations poses varied seismic demand on structures. In the present study, out of 184 ground motions recorded at 23 recording stations of Indian subcontinent, about 67 ground motions are quantified as strong ground motion based on PGA and Duration of the motion. Response Spectrum for each strong ground excitation is developed. A mean, mean plus one standard deviation and maximum response spectrum are developed for each strong ground motion using statistical analysis. Seismic demand posed by each response spectrum and IS specified design spectrum on four storey Reinforced Concrete (RC) shear frame building are evaluated. Comparison among seismic demand represented by peak acceleration and base shear are carried out. It is found that seismic demand posed by IS specified design spectrum for building is quite high as compared to mean response spectrum. Similar results are obtained for mean plus one standard deviation and maximum response spectrum except few strong ground motions that posed high seismic demand on building as compared to IS specified design spectrum.

Abstract

Construction of tall and flexible structures has become easier now-a-days because of advances in analytical techniques and availability of more efficient materials. However, these structures are more sensitive towards dynamic loadings. Dynamic response of such structures under various excitations can be quantified by displacement and acceleration response time history. Excessive dynamic response of structure leads to substantial damage to the structural components and hence it need to be controlled. Passively, this is achieved by adding either mass or stiffness or both of them. This paper covers experimental study on controlling dynamic response of a building model using two types of bracings, namely, Concentric- and Eccentric bracing. A building model is fabricated using aluminum flats and plates and bracings are fabricated using linear springs of moderate stiffness. A model represented as Single Degree of Freedom (SDOF) system is subjected to sinusoidal excitations of various frequencies through small scale shake table. Acceleration response of a uncontrolled building model (model without bracings) is obtained using accelerometers and Data Acquisition System (DAQ) – LabVIEW 8.0. Displacement response is derived through numerical integration from acceleration response using LabVIEW. Acceleration and displacement response of controlled building model (model with bracings) are extracted and compared with uncontrolled system. Dynamic properties like Natural Time Period and Damping Ratio for both types of bracing systems are obtained and comparisons are made among them. It is found that natural time period and damping ratio of controlled building model is increased as compared to uncontrolled system due to stiffness addition. Displacement and Acceleration response are reduced appropriately for controlled system as compared to uncontrolled system.

Abstract

t Instantaneous Optimal Control is used to obtain desired force from MR damper fitted to a seismically excited building. Excitation is considered when minimizing performance index, unlike in classical optimal controllers. Modified Bouc-Wen damper model and on-off voltage law is considered. Various forms of state weighting matrix are considered for controller design. IOC is compared with LQR/LQG and PON control. It yields reduction in: maximum peak interstorey drift; and generally in accelerations vis-a-vis LQR/LQG. IOCSF Riccati Matrix Type controller appears most effective, yielding: lowest maximum peak drift/acceleration and generally best storeywise drift control vis-a-vis PON/LQR/LQG; substantially lower peak accelerations vis-a-vis LQR/LQG.

Abstract

Analysis and Design of berthing structures seems to be a new subject to common structural engineers, but they are the important structures contributing to the development of trade in our nation. The paper is focusing on analysis and design of 12th Cargo Berth at Kandla, which is open piled structure with retaining wall at the land side and lying in high seismic zone V. The berth is to be designed for a vessel having capacity of 75,000 DWT and the structure is supported on Bored cas-in situ piles. The structure is subjected to various forces and combinations such as cyclone, high tide, earthquake,high winds, heavy live loads as per IS: 4651 – 1983. A 3-D model was generated using STAAD-Pro software and analysis was conducted with appropriate loads acting on the structure. It was observed that seismic force was governing in most of the case because of Kandla being located in high seismic zone V. The paper is an attempt to understand the behavior of offshore structures under different conditions of loading and also, an effect of seismicity on the structures.

Abstract

Conventionally, seismic design of building structures is based on the concept of increasing the resistance capacity of the structures against earthquakes by employing, Shear walls, Braced frames or MR frames. However, the periods of vibrations of above mentioned structures are primary tools in determining seismic response. The period of vibration of structures is highly varied in nature depending upon its determination approach. This paper is an attempt to focus the issue of variation of time period determination from empirical formulas to software model implementation. In this paper a small R.C.C. Building of G + 4 size has been taken and different modeling aspects were applied to evaluate the difference in time period of the building. Based on the evaluated time periods the equivalent static lateral loads on the building were also estimated and distributed along the height of the building. The software used to model the R.C.C. building is ETABS Nonlinear Version 8.11. Lastly, a comparison of time periods for different types of model and base shear were also obtained. Overall, the paper is a modest attempt to bring in front the basic issues of obtaining time period for correct evaluation of seismic response of R.C.C. buildings, which felt missing.

Abstract

The paper presents an experimental investigation of the flexural behaviour of reinforced concrete (RC) beam elements strengthened externally with stainless steel wire mesh (SSWM). SSWM has the potential to be an alternative composite material in place of Carbon Fiber Reinforced Polymer (CFRP) and Glass Fiber Reinforced Polymer (GFRP) because of advantages such as being cost-effective, having more fire-resistance and corrosion resistance, good bond behaviour with concrete, improve the strength of members, leaving minimal effects on structural aesthetics as it has less thickness and ease in availability. In the present study, SSWM has been wrapped externally over the beams having three different wrapping patterns, including fully wrapped vertical SSWM strips over the beam, partial wrapping of vertical SSWM strips in between the stirrups of the beam and partial wrapping of vertical SSWM strips above the stirrups of the beam, and control beam with no wrapping, each configuration having two test specimens. Results of experimental investigation in terms of cracking load, ultimate load, corresponding deflection, ductility, initial stiffness and energy absorption capacity of different wrapping patterns have been obtained and compared with those of control beam specimens. From the results obtained, it has been demonstrated that the fully wrapped SSWM strip wrapping pattern enhanced the flexural strength of the beam and showed the highest strength gain compared to the other wrapping patterns.

Abstract

The present study evaluates the behaviour of wet precast beam-to-beam connection under pure torsion through experimental and numerical studies. A wet connection is provided at the central region of the precast beam. Two precast beam elements are connected by welding the overlapped portion of reinforcement bars projecting from each beam element. Furthermore, inward and outward shear keys are provided within the connection region to examine the efficacy of shear keys on the torsional resistance of the precast beam. Also, the behaviour of precast beams with and without shear keys is compared with monolithic beams. Experiments are conducted using a loading frame, designed and fabricated to create a pure torsion effect on the beam specimen under the application of monotonic vertical load. The response of test specimens is evaluated through various parameters such as torque and corresponding twist at different phases of loading, torsional ductility index, crack formation and failure propagation. Experimental studies show that shear keys provided within the connection region effectively contribute to force transfer and enhance torsional resistance of the precast beam by 16 %−24 % as compared to monolithic beam and precast beam without the shear key. A numerical analysis of the precast beam is carried out, and the behaviour of test specimens obtained from experimental studies is compared. The damage pattern and torque-twist behaviour obtained from numerical studies adequately simulate the response of test specimens observed during the experimental study.

Abstract

Partial confinement can provide sufficient reinforcement to enhance the compressive strength and ductility of concrete with lesser confining material. This paper presents the results of an axial compression test conducted on eighteen plain concrete cylinders of 150 mm diameter and 300 mm height partially confined with a Stainless-Steel Wire Mesh (SSWM) strip of different widths. The study included two specimens without wrapping, two fully wrapped specimens, and others wrapped with two SSWM strips of varying widths at both the ends of concrete cylinder. The strain on SSWM up to failure is measured to understand the effectiveness of lateral confining pressure on the behaviour of concrete cylinders. The peak axial compressive strength and corresponding strain of unconfined and SSWM-confined concrete cylinders are compared. The result shows a significant increase in peak confined compressive stress as compared to an unconfined concrete cylinder. However, the confinement efficiency is reduced when the height of the unconfined region exceeds the diameter of the cylinder, and significant strain localisation is detected within the unwrapped region. Based on experimental investigation, a confinement coefficient is suggested for a partial wrapping of SSWM on the concrete cylinder.

Abstract

The torsional strengthening of reinforced concrete hollow beams (RCHBs) with externally bonded stainless steel wire mesh (SSWM) was investigated. The experimental programme involved casting and testing eight RCHBs of length 1300 mm and 150 mm × 150 mm cross-section with a 50 mm × 50 mm square hollow section in the centre. The beams were reinforced with 4–10 mm dia. longitudinal bars and 8 mm dia. stirrups at 150 mm centre to centre. Two unstrengthened RCHBs were designated as control specimens and the other six beams were strengthened using three different SSWM wrapping configurations. The test results were analysed based on torque–twist behaviour and the influence of SSWM on cracking torque, ultimate torque and failure modes. A numerical model was developed to predict the behaviour of RCHBs using the finite-element (FE) software Abaqus. The predictions of peak torque and corresponding twist obtained from the FE modelling showed good agreement with the experimental results. Based on the outcomes of this study, SSWM can be considered a feasible material for the torsional strengthening of reinforced concrete elements.

Abstract

The research on flexure, shear, and axial strengthening of reinforced concrete (RC) members has been conducted many times, but very few studies have been carried out on torsional strengthening of RC members. The main objective of the present study is to ascertain the better strengthening material in terms of torsional strength and damage patterns. A finite element (FE) study is carried out using ABAQUS software to understand the behavior of RC beam strengthened using different fiber reinforced polymers (FRPs), i.e., carbon fiber reinforced polymer (CFRP), glass fiber reinforced polymer (GFRP), and stainless-steel wire mesh (SSWM). Total sixteen beams are adopted from literature. One beam is kept as a control beam, while the other fifteen beams are strengthened using CFRP, GFRP, and SSWM with five different wrapping configurations. Torque-twist response, ultimate torque and corresponding twist, damage pattern, and maximum principal strain are measured and compared with experimental results from the literature. The study reveals that the effectiveness of SSWM as a strengthening material is as good as CFRP and GFRP in terms of torsional strength, failure pattern, and maximum principal strain.

Abstract

The present study aims to evaluate the effectiveness of externally bonded stainless steel wire mesh (SSWM) in enhancing the shear strength of reinforced concrete (RC) flanged beams with T-shape cross-section. To identify appropriate SSWM as a strengthening material, tension test and bond test are performed on five locally available SSWM. An experimental investigation is conducted to study the behaviour of RC T-beams strengthened by externally bonded 40 × 32 type SSWM under transverse loading. Two beams are considered as control specimen, and four beams are externally strengthened by two different wrapping configurations. All beams are tested under the two-point loading until failure. Results of experimental investigation, in terms of cracking load, ultimate load, deflection, prove the effectiveness of SSWM in shear strengthening of beams. The numerical model of controlled and SSWM strengthened T-beam specimen is also developed using finite element based software ABAQUS to validate experimental results.

Abstract

This paper presents the outcome of the experimental program conducted to incorporate the Nanoparticles in the pervious concrete for the purpose of water purification and improvement in the strength. The Nanoparticles are small objects that behave as filler for the porosity of concrete, which helps to increase the strength of concrete and maintain the perviousness of concrete. This perviousness of pervious concrete helps to purify the contaminated water also. Three Nanoparticles Zinc Oxide (ZnO), Charcoal and Manganese Dioxide (MnO2) are used in the present experimental program. The quality of the water is checked by the tests such as Hardness test, pH test, turbidity test, Porosity and Permeability test perform to check the inherent property of pervious concrete and compressive strength test performs to check the improvement of Pervious concrete. The result shows charcoal provide good results for water purification and improvement of strength as comparing other two Nanoparticles.

Abstract

Flood mapping has been crucial to flood hazard identification, mitigation, and preparedness. Development of accurate flood maps in data-scarce regions has always been a challenge. This study presents a multi-stage approach involving topographic feature extraction, CNN-based flood classification, and regression modeling for flood mapping. The study aims to provide accurate estimates of flood depth by leveraging both spatial data and image-based contextual information. The methodology comprises two CNN models followed by a regressor for estimating flood depth using geo-tagged flood photographs. The first CNN model identifies the existence of flood, while the second one identifies the flood severity class (greater than or less than 1 m depth). A modified VGG-16 CNN architecture is employed in the present study for both stages. Finally, the AdaBoost Regressor is employed to estimate precise flood depth using topographical data such as elevation, slope, and topographic position index (TPI) values as the input. The model results showed excellent performance with R2 of 0.93 and RMSE of 25.01% when tested on manually collected flood data for VGP Selva Nagar, a residential area in Chennai, India, for the December 2023 flood. Comparison of the VGG-16 CNN architecture with other standard architectures, such as ResNet50 and InceptionV3, showed the efficacy of the presented model. The presented multi-staged approach, thus, proves to be an effective tool that relies only on geo-tagged flood photographs as the input to develop accurate flood maps. The models developed in this study have significant implications for flood management that can help inform emergency response teams about flood severity and extent, facilitating prompt and effective interventions.

Abstract

Floods are one of the most disastrous events, that can cause extensive damage to property and infrastructure, and can also be deadly. Out of the several impacts, one of the impacts of flood is the disruption of essential services such as electricity, water, and transportation. The closure of roads due to extreme weather conditions lead to significant impacts such as human safety, as well as social and economic threats. Thus, it becomes essential to determine roads that are highly prone to submergence under the situation of a flooding event. In the present study a methodology is presented to identify potential road blockages due to floods using satellite images and topographical data. The road information, such as the layout and the geographical co-ordinates, are extracted from the satellite images using advanced image segmentation. In order to acquire the topographical data of the location, the digital elevation model (DEM) of the desired area is extracted using Rasterio Python Library. The clustering of the elevation in DEM data into different classes is then carried out using K-means clustering approach. The road segmentation data is integrated with the elevation cluster data to identify the elevation regions proximate to roads. The methodology is applied on the rural part of Bengaluru city, Karnataka, India. The results showed 95% proximity to road blockage due to a past flooding event on 4th November 2022. The present model thus can significantly aid proactive disaster management and planning, minimizing the impact of floods on transportation routes.

Abstract

In regions with limited flow and catchment data needed for the configuration and calibration of hydraulic and hydrological models, employing spatial flood modeling and mapping enables authorities to predict the spatial extent and severity of floods. This study leveraged flood inventory data, coupled with various conditional variables, to formulate a novel Ensemble model. This ensemble model combined four hybridized models based on Support Vector Machine (SVM), Naïve Bayes (NB), Decision Classification Tree (DCT), and Artificial Neural Network (ANN), all of which were optimized using the metaheuristic Symbiotic Organisms Search algorithm (SOS). The precision of the flood inundation map generated by the four hybrid models and the ensemble model was assessed using standard metrics. The results demonstrated that the ensemble model outperformed other models, with an accuracy metric of 0.99 Area Under the Curve (AUC) during the training stage and 0.96 during the testing stage. This underscores the effectiveness of the ensemble approach in flood preparedness and response applications. Furthermore, a comparison was conducted, comparing the performance of the developed ensemble model against other studies within the state of West Bengal. The findings highlighted a significant improvement in the ensemble model's performance with an AUC score of 0.96 in validation compared to studies in similar areas within West Bengal with AUC score ranged from 0.73 to 0.92. In conclusion, the methodology employed in this study holds promise for application in other regions worldwide that face challenges related to limited data availability for accurate flood inundation mapping.

Abstract

The reliability of Water Distribution Networks (WDNs) is a critical topic that has been explored by many researchers over the last few decades. Nevertheless, this research domain has gained momentum in the last decade. WDN reliability was addressed in the literature using different approaches and techniques. This study presents a bibliometric analysis and scoping review of the progress and gaps in research on WDN reliability. The analysis was performed on a total of 347 articles from 2000 to 2022, which were retrieved from the SCOPUS database. The bibliometric analysis identified trends and gaps by focusing on articles output, citation network of articles, coauthorship and collaboration analysis, co-citation, and clustering analysis. In addition, coupling keywords analysis with thematic maps analysis helped identify basic, niche, emerging, and declining research themes in the field of WDN reliability. Three major research themes were found: WDN optimization, reliability assessment, and consideration of GHG emissions and energy-cost for WDN expansion. Reliability surrogate measures (RSMs) were found to be one of the most widely researched topics in this field. Performance assessment of various RSMs, as well as the consideration of energy and cost for WDN design and expansion stood out as the emerging trends for future research in the field of WDN reliability

Abstract

The design of a water distribution network (WDN) is an optimization problem that is computationally challenging with conflicting objectives. This study offers an enhanced Chaotic Sobol Sequence-based Multi-Objective Self-Adaptive Differential Evolution (CS-MOSADE) algorithm for multi-objective WDN design. The CS-MOSADE algorithm was tested on two benchmark WDNs, and a real WDN. Optimization results indicate that the CS-MOSADE algorithm converged two to three times faster than the MOSADE and NSGA-IIalgorithms and led to better output in terms of even distribution of solutions and convergence towards the true Pareto-optimal front. Smaller spacing metric indicated better uniformity in the obtained solutions; and larger hyper-area and coverage function values depicted better convergence towards the true Pareto-optimal front for the CS-MOSADE algorithm compared to the other algorithms. The CS-MOSADE algorithm was then applied to solve a WDN expansion problem for optimal pump scheduling and minimization of Life Cycle Cost, maximization of reliability and minimization of Green House Gas (GHG) emissions. A significant reduction in GHG emissions of 2.17 x 106 kg was achieved at an additional cost of $0.55 x 107 when optimal pump scheduling was incorporated in the model of the real WDN over service life of 50 years.

Abstract

India witnessed its first case of coronavirus infection (COVID-19) on January 27, 2020, in Kerala, India. Since then, the infection has spread rapidly across the country and the pandemic outbreak has affected all industries severely including the construction sector. This study aims to understand the effect of the COVID-19 pandemic on the construction sector, particularly the ready-mix concrete (RMC) industry. An attempt was made to investigate the liabilities and the losses incurred by the RMC industry in terms of income and change in the production of concrete during the coronavirus outbreak. A preliminary survey was carried out to create a database of the RMC plants located nearby the study area i.e., Ahmedabad City in the state of Gujarat, and to prepare a questionnaire using google forms. The RMC plants were visited and from the inputs of RMC officials, statistical insights were drawn. The study reveals that during the COVID-19 lockdown period there was almost a 40% loss in concrete production & 60% loss in the income generated by the ready-mix concrete industry. In addition to this, it was also found that the industry had to pay off liabilities like land rent, electricity bills, staff salaries, etc. during the time of the pandemic. This study provides the opportunity for RMC plants to identify the vital elements involved in the operation of the plant which can be affected due to such pandemic and provides guidelines to reduce the effect of any such pandemic on the plant’s production & sales by ensuring the stability of all assets involved in its supply chain.

Abstract

The Economy of all countries is developing at a rapid pace and to maintain equilibrium between nature and growth, it needs to conserve all its natural resources. Full progress can be achieved by any country if it uses all the natural resources equitably including the most important water. This investigation was mainly focused on two criteria, in the first criteria was to eliminate the fine aggregate from concrete and the other was to allow water to pass through the concrete. Due to the consideration of these two criteria, this type of concrete is known as pervious concrete (PC). The purpose of this investigation was to develop mixture design and mixture proportioning charts for PC. The main properties studied include compressive strength, density, and permeability and void ratio. To measure the permeability of the PC, a test setup was created in the laboratory. The falling head test method was used to evaluate the permeability coefficient for PC. PC was produced using two sizes of natural coarse aggregates. The first group is 4.75–10 mm i.e., size A (passing from 10 mm and retaining on 4.75 mm IS sieve) and the second group is 10–20 mm i.e., size B (passing from 20 mm and retaining on 10 mm IS sieve). The cement content was used in the range 250–400 kg/m3 for the experimental investigation work. The aggregate/cement ratio was used 4:1. Three w/c ratio were used i.e., 0.3, 0.35 and 0.4, respectively. It has been observed that for 4.75–10 mm size aggregates, the compressive strength is more as compared to 10–20 mm size aggregates. Other PC properties such as void ratio, permeability were not much affected by changing coarse aggregate size. Based on the PC property results, PC mixture design charts were developed. The step-by-step process of PC mixture design was developed with the help of PC mixture design charts. This mixture proportioning method may be useful for the development of the preliminary mixture design of PC.

Abstract

Rapidly growing and uncontrolled changes in the natural landscape due to human intervention has created a serious problem of rainwater harvesting in many Indian cities. Rainwater is seen getting wasted on the roads due to lack of proper design of drainage system. Construction of Pervious concrete pavement (PCP) is one of the best method to solve this problem. The pervious nature of the pavement is suggested to act as a drainage pipe and the water accumulated on the road or pavements drains out immediately. Therefore, an attempt has been made for the construction of PCP in this present study. The PCP was constructed at Nirma University campus, Ahmedabad, India for study purpose. The size of PCP stretch was 3 m × 10 m. The details of construction methodology and material used for the construction of PCP are included in this paper. In addition to that, properties of pervious concrete (PC) such as void ratio, compressive strength, permeability and density were evaluated and compared with field investigation results. The 28 days results of PC field cores and cast specimens achieved similar range for compressive strength and void ratio. Moreover, maintenance schedule was prepared for the supervision of PCP. The infiltration rate was measured at different intervals to determine if there was clogging in the PCP. Based on the results of this investigation, it is seen that there is successful drainage performance of the PCP, demonstrating the possibility of construction of such pavements in the water logged areas of India.

Abstract

This paper focuses on developing concrete mix design using the android application as per the Indian Standard IS: 10262 (2019). Concrete mix design is an essential parameter for constructing any reinforced concrete (RC) structures. Recently IS: 10262 (2019) has come up with significant changes in the concrete mix design. IS: 10262 (2019) has added the mix design of different types of concrete such as ordinary concrete (M30 to M60), selfcompacted concrete, high strength concrete (M65 to M100), and mass concrete. Currently, on the Google play store, such an application is not available, covering all types of concrete mix design according to IS: 10262 (2019). Concrete mix design android application has been developed for all types of concrete using all the provisions mentioned in IS: 10262 (2019). This android application covers the mix design of ordinary concrete, self-compacted concrete, high-strength concrete, and mass concrete. The android studio was used to develop a concrete mix design for the android application. This concrete mix design application also provides detailed guidelines for mixing proportions specified in IS: 10262 (2019). Experimental work was carried out to validate android application results for concrete mix design. Compressive strength result at 7 days and 28 days was measured and compared with a target mean strength for different types of concrete. A slump test was carried out to check the workability of different types of concrete. From the compressive strength result, it can be concluded that the concrete mix proportioning result obtained from the android application will be helpful for field applications. This android application has excellent benefits to the students, academicians, and practicing engineers working on concrete mix design.

Abstract

Corrosion is the degradation of a metal by an electrochemical reaction with its surrounding environment. The corrosion of embedded steel reinforcement in concrete causes durability issue in reinforced concrete structures and cement concrete pavements. The impact of corrosion of embedded steel rebars on the performance of reinforced concrete structures and pavements is a subject of concern for the engineers and scientists working in the construction industry. One of the effective ways of studying such influence is to understand the effect of corrosion on the mechanical and durability properties of concrete. The bond strength between steel rebar and concrete is also an important parameter of study. This study focuses on probing the effect of corrosion on bond strength and other mechanical properties of reinforced concrete. A pull-out test was conducted on 18 concrete cube specimens having steel bars of 12 and 16 mm diameter Fe500 grade. These bars were corroded with the help of commercial grade hydrochloric acid solution 10% v/v. Each group of bar specimens included three levels of corrosion: 0, 3 and 5%. Tension test on steel bars and compression test for concrete cubes were conducted
