Abstract: A mixture model of two-phase flow to simulate sediment transport has been introduced as following, and the velocity distributions of flow and volume fraction of sediments were given when the flow carries sediments with two different diameters respectively. The theoretical result of the velocity distribution almost matched with experimental data.The distribution of sediment on the bottom of flume was analyzed qualitatively and satisfied with general rules. So, this model was considered reasonable to simulate sediment transport for low sediment concentration. In the paper, we used the mixing model to forecast the sediment distribution of Yazidang reservoir.
