Abstract

The results of numerical study of the influence of submarine ridges on the gravitational current on the slope of the laboratory scale and on the transformed under the Ronne-Filchner ice shelf flow of water into the Weddell Sea. For the computation of the laboratory-scale flow and of the seawater flow over the continental slope the non-hydrostatic and hydrostatic versions of the POM model were used, respectively. The processes of vortex shedding over a slope and the influence of one or two undersea ridges on the near-bottom flows were considered.
