abstract: in this paper we consider the problem of non-stationary pressure filtration in a two-layer porous medium, when the functions are given on the boundary with time.This mathematical model was introduced a function of reducing the head, after which we moved to dimensionless variables by puttingand obtained the original model ( 1).The mathematical model is solved by the method of finite differences using the sweep method, using implicit schemes.The program is compiled on MathCad where the convergence
