Abstracts:

The software package for numerical modeling of anthropogenic polutions in the field of internal waves is presented in the paper. Research based on numerical simulation of the balance equation of the surface concentration and implicit finite-difference method. Film dynamics considered in the advection - diffusion - relaxation model. The model was tested on a series of analytical solutions of advection-diffusion equation of impurity transport. Internal waves field based on Gardner-Ostrovsky equation with respect of Coriolis forces in stratified basin. Input data for calculation of near-surface speeds are internal waves characteristics based on international atlas of hydrological parameters GDEM and bathymetry ETOPO1.
