Groundwater quality varies due to the chemical, geochemical, and biochemical reactions of the pollutants in the subsurface flow systems. To reliably predict the fate of contaminant transport in groundwater, an accurate numerical modeling is required. Analytical and numerical simulation models help civil engineering to understand the physical and chemical processes that influence contaminant transport through a saturated soil layer, including advective and dispersive transport as well as sorption.In the present investigation, An attempt has been made to provide a simple but sufficiently...
