With the help of mathematical modeling, the features of the distribution of North Sea waters in the Bornholm basin are considered on the example of a large inflow occurring in January 2003. For better resolution of bottom processes in the bottom density flow model, the computational domain is split vertically into bottom and overlying areas. In the lower region with a thickness of 20 m, the vertical grid spacing is 1 m. The basic equations of the model are transformed for each of the regions using σ-coordinate. According to the simulation results, the features of the distribution of North Sea water are highlighted, as well as the associated change in the salinity field in the overlying layer. Estimates of the possible influence of runoff currents on the distribution of North Sea waters are obtained.
