Abstract: A numerical model for studying the dynamic mixing of the sea and the river waters in the estuarial area is proposed. Computations are based on the two-dimensional longitudinal vertical stratified fluid mechanics equations and the equation of transport of salt. The model focuses on the reproduction of the local density currents at the mouth of arms branched deltas of the rivers of Siberia. The results of numerical experiments are given, the dynamic structure of the flow and salinity profiles are compared to the observational data.

Key words: numerical simulation, turbulence, gradient-density flows, river flow, sea area, transport of salt.
