The modeling heavy metal transfer by the ground source to the lower boundaries of the soil is considered. The transfer process is described by a system of equations included the Navier-Stokes equation, the k-ε model and the nonstationary diffusion equation. The initial and boundary conditions are given at the boundaries of the air and liquid in the soil flow, also in the air-ground contact zone, which are necessary for solving the boundary value problem. The results of numerical simulation obtained using the ANSYS fluent program are shown. The result analysis is based on the comparison of numerical modelling and long-term observations data around the hydroelectric power plant.
