STUDY OF MOVEMENT OF TWO-DIMENSIONAL CONTAMINANTS IN UNSATURATED POROUS MEDIA WITH UNIFORM FLOW

Abstract

Contaminants released at the surface of the earth pass through the soil and contaminate the underlying ground water. Here we obtain two-dimensional mathematical model for movement of radio active contaminants through unsaturated porous media with uniform flow. The advection dispersion equation is solved subjected to the given boundary conditions. The analytical solutions of the non-linear partial differential equations are obtained using integral transform techniques in terms of error functions.
