The interaction between surface and groundwater flow in a non-prismatic river has been a topic of interest among researchers since last three decades. Existence of piedmont zone in the river bed changes the downstream flow ...
This research is aimed at developing a methodology to identify episodic conditions caused by air pollutants (Carbon Monoxide (CO), PM2.5 and Black Carbon (BC)) released from the traffic in an urban traffic corridor, to ...
The shear strength of soils is one of the important aspects to be considered in any geotechnical activity. The problems concerned with the bearing capacity of road subgrade, slope stability of embankments and the design ...
The soils which show volumetric changes due to changes in their moisture content are referred to as expansive soils. With increase in moisture content, these soils swell and with decrease in moisture content undergo shrink. ...
With the increasing demand for renewable and environment friendly energy, wind turbine farms are moving seaward due unavailability of suitable land locations, noise pollution produced, visual impact on the natural environment, ...
The presence of vegetation in the upper layer of vadose zone results in complex moisture dynamics (soil-plantatmosphere interaction) due to the combined effects of transpiration and soil water evaporation. Unsaturated ...
In this study, the individual or combined effect of fly ash and tyre fibre on stress-strain-strength characteristics of two soils, a fine-grained residual lateritic soil (red soil) and granular riverbank sand (Brahmaputra ...
A rapid increase in industrialization is leading to the generation of high metal toxicity to the ecosystem. Landfilling has been carried out as the most preferred method of waste disposal around the globe. In the present ...
Due to rapid urbanization and industrialization, the geoenvironment and groundwater reserves in most parts of the world are getting damaged due to the harmful effect of pollutants disposed off into the geoenvironment. Due ...
Aerobic granular sludge (AGS) technology is developed in the last two decades for the treatment of wastewater. Because of having unique properties like high settling behavior, compact structure and ability to withstand ...
Anaerobic digestion (AD) of pulp and paper mill sludge (PPMS) was studied with and without pretreatment, in biochemical methane potential (BMP) assay, batch and with a semi-continuous lab scale reactor. Initially, AD of ...
Passenger car equivalent (PCE) values are required while representing a non-homogeneous (mixed) traffic stream in terms of a homogeneous (base) traffic stream. For the traffic conditions prevalent in India, researchers ...
Solutions to prevailing traffic conditions in the cities of developing countries can be either in terms of efficient traffic management and operational strategies or by expanding the existing infrastructure according to ...
Analysis and modeling of mode choice behavior is essential in formulating appropriate transport policies. Discrete choice models, based on the random utility theory, are widely used in modeling the individuals choice ...
In this work, an effort is being made to obtain an analytical solution to the problem of groundwater flow into a network of equally spaced ditch drains in a stratified soil underlain by an impervious barrier. The problem ...
Analytical expressions are derived for predicting flow into an auger hole in an unconfined aquifer of finite horizontal and vertical extents and underlain by an impervious substratum. Solutions are provided for two cases, ...
The impact of heavy metal pollution on environment due to industrial effluent is a global concern. adsorption technique is one of the well proven metal removal techniques due to its several advantages over conventional ...
In the last few decades, climate change has emerged as a major threat to natural systems. Climate change has affected the climatic patterns around the globe and is affecting the hydrology and ecohydrology in different river ...
Groundwater is the major source of domestic water for people living in rural and semi-urban area of Assam D a northeastern hilly province of India. However, it contains excessive amounts of fluoride (F-), arsenic [As(III)] ...
The present work is aimed at carrying out kinetics, equilibrium and column studies for metal removal/uptake under uncontrolled/controlled pH conditions by granular activated alumina (GAA) from mono-, binary- and ternary-metal ...
