Computer complex for modelling of sea currents using regularized shallow water equations

The paper describes the computational system for modeling sea currents, which is based on a hydrodynamic model with regularized shallow water equations. A system of regularized equations is presented and a methodology for its solution is briefly described, including an algorithm for calculating dry-bed areas. A parallelization efficiency test of the program code on a high-performance computing system was carried out. Acceleration curve obtained. The structure of the program and its interaction with external modules are described. Test calculations of tidal fluctuations of the northern seas have been carried out. The calculated area covers the White Sea, the Pechora Sea, parts of the Barents and Kara Seas, as well as the Kara Gates Strait. The results obtained describe well the tidal phenomena in the study area.
