It uses a shaloow water system coupled with the bedload sediment transport equation describing the evolution of the topography/ The numerical approximation of such system is based on a splitting method, solving first shallow water equations on a time step and after updating the bottom shape/ The algorithm developed is applied for simulation of 1D non-stationary hydraulic flows above irregular non-cohesive bottom. Detailed analysis of empirical model that describe bedload sediment transport rate is carried out.
