| Abstract: | A finite simulation of 2-D flow and sediment mathematical model is established in the article. Simulation calculation is carried out on Baguazhou reach of the Yangtze River and shows that the calculated results such as water level, velocity field, discharge division, erosion and deposition are in complete agreement with the field data. All these have proved that the model is creditable. |
