Abstract
A mathematical model to predict the process of the mass transfer of multicomponent pollutants in the multilayer piecewise-homogeneous isotropic water saturated not deformable porous media, which have the form of the model curvilinear parallelepiped, bounded two equipotential surfaces and four surfaces flow, separated by some specified of the equipotential surfaces on several subdomains, which are characterized by different coefficients of filtration, active porosity and diffusion, is constructed. The algorithm for numericallyasymptotic approximation of solution of the model problem is developed. The results of numerical calculations and conducted their analysis.
