Sediment transport mathematical modeling in a coastal zone using multiprocessor computing systems

A nonstationary two-dimensional model of sediment transport in a coastal zone of reservoirs is considered. The following physical parameters and processes are taken into account: the soil porosity; the critical value of the tangent tension for which the sediment movement begins; the turbulent exchange; the dynamically variable geometry of the bottom and the level elevation function; wind currents; and the friction on the bottom. Two-dimensional and three-dimensional models of hydrodynamics in a coastal zone of reservoirs as well as a transport model for weighted particles are constructed and are implemented on a distributed computing cluster. A number of numerical results are discussed.
