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

Coupled non-stationary two-dimensional models of deposits transportation and hydrodynamics processes have been presented in a coastal zone of shallow water basins. The deposit transportation model is taking into account the following physical parameters and processes: porosity of bottom deposits, critical value of tangential tension, for deposit moving, turbulent exchange, dynamically changing bottom shape and variable function elevation, wind currents and bottom friction. Discretization and numerical algorithms have been presented for constructed models. The complex of programs was constructed and results of numerical experiments were given on the basis of the developed algorithms.
