Mathematical modeling of sediment transport in the coastal zone of shallow reservoirs

A nonstationary spatial two-dimensional model of sediment transport in the coastal zone of water reservoirs is considered, taking into account the following physical parameters and processes: the porosity of soil, the critical shear stress at which sediment begins moving, turbulent exchange, the dynamically changing geometry and function of the bottom elevation level, as well as wind currents and friction on the bottom. The hydrodynamic spatial two-dimensional model of sediment transport in the coastal zone of the reservoirs is also considered. For the proposed mathematical models their discretization has been fulfilled. Based on the developed algorithms a complex of programs has been built and the results of numerical experiments are presented.
