Analytical Modeling of Solute Transport in a Two-Zoned Porous Medium Flow

The objective of this study is to model the transport groundwater contamination in one-layered and two-zoned porous medium flows by an analytical approach. one-dimensional advection–dispersion equation (ADE) has usually been used describe problems pollutant a water environment. This presents some exact solutions ADE examine variation solute concentration with without biodegradable effect unconfined aquifer finite domain generalized integral transform method (GITM). modeling results for show that more sensitive Peclect number than retardation factor first-order decaying coefficient uniform flow. In composite soil zones, diffusion factors have significant effects on around interface, especially over long-term period. flux between two regions determined gradient at interface regions. contaminated decreases as factor, number, increase every location fixed duration. Moreover,
