Abstract: A fresh water basin is considered to be connected with the sea as a source of the salt pollution. Near the front part of basin there is a transverse tranch which can accumulate excessive salt in and then remove it from. The aim of the paper is to simulate the salt pollution under the action of nonlinear water waves taking into account the floor performance. The corresponding mathematical model is presented as the initial boundary value problem on the finite interval xε[O, L]. The governing equations include the system of four coupled partial differential equations for the longitudinal velocity u (x, t), the sa- linity s (x, t), the depth h (x, t) and sediment tran- sport Q (x, t). Two cases are considered. In the first case the wave motion is described by nonlinear shallow water wave equations. In the second case KdV equation is taken as governing and the initial solution profile is given. The results of numerical calculations are presen- ted graphically and analysed.
