Abstract

Predict of sediment particles movement is important mater, that can be help engineers to control flow structures, dams reservoirs, irrigation systems and etc. Simplification and sufficient sensible resolute cased to select one dimensional (1-D) approach for simulation of sediment transports. In this study we tried to simulate 1-D phenomena of sediment transport with explicit and implicit schemes in equilibrium conditions. In order to solve government equations used finite volume method by upwind scheme. Finally the model has been verified by Laboratory research and the results are generally fitted well in with the measurements
