Analytical Modeling for Solute Transport in a Homogeneous Medium

In the present scenario, developing countries are experiencing a rapid growth due to urbanization. Many of the watersheds of India are facing water quality issues caused by anthropogenic sources like high industrialization, population growth, and urbanization. Fluid flow and solute transport to the subsurface environment are the most detrimental activities in the urbanized area and it is one of the biggest challenge facing watershed managers. As it is very difficult to eliminate the source activities permanently, a thorough understanding of flow processes combined with transport mechanisms is required in order to minimize such water quality hazard. This study seeks an interaction of principal transport mechanisms like advection and dispersion and its effect on solute movement. To solve and analyze these problems, an analytical scheme is used which is based on a mathematical combination of the variational iteration method and the homotopy perturbation method. Sensitivity analysis is carried out with changing transport parameters like velocity and dispersion of the media and concentration profiles are studied using the analytical model. It has found that the potential of solute concentration is more with the high flow velocity and however conversely varies with respect to the dispersion of the porous medium.
