Multispecies solute dispersion with variable porosity in semi-infinite saturated porous media
Multispecies solute dispersion with sequential first-order decay often occurs in contaminated geological formation with radioactive wastes and their biodegradation products. As a result, analytical result is a...

Advances in analytical solutions for time-dependent solute transport model
This study adopts generalized dispersion theory in one-dimensional advection–dispersion equation (ADE), where time-dependent dispersion and velocity are considered. The generalized dispersion theory allows mec...

Influence of fluid viscosity and flow transition over non-linear filtration through porous media
The present study investigates two important though relatively unexplored aspects of non-linear filtration through porous media. The first aspect is the influence of viscosity variation over the coefficients o...

Mathematical modelling to establish the influence of pesticides on groundwater contamination
Groundwater contamination due to pesticides used during cultivation was modelled mathematically, assuming that both the soil and the aquifer were initially contaminant free and the source of contamination was ...

Groundwater contamination in mega cities with finite sources
Groundwater contamination due to multiple sources occurring in mega cities was modelled. One constant source contamination was considered at the source boundary, whereas other sources may join in between at va...

Solute transport in a semi-infinite homogeneous aquifer with a fixed point source concentration
This study derives an analytical solution of the advection–dispersion (AD) equation commonly used to describe the transport of pollutants in a semi-infinite homogeneous aquifer. When an extra constant source t...

High resolution DEM generation for complex snow covered Indian Himalayan Region using ADS80 aerial push-broom camera: a first time attempt
Updated and Accurate Digital Elevation Model (DEM) of snow covered and glaciated mountainous area is essential for many applications such as avalanche hazard and numerical modelling of mass movements or mappin...

Longitudinal dispersion with time-dependent source concentration in semi-infinite aquifer
An analytical solution is obtained to predict the contaminant concentration along unsteady groundwater flow in semi-infinite aquifer. Initially, the aquifer is not supposed to be solute free, i.e., aquifer is ...
