| Abstract: | The 2-D sediment numerical model is built by using the Environmental Fluid Dynamics Numerical Model considering the boundary conditions. The sediment concentration and the deformation of riverbed of this model are verified by the measured date. The change in scour and fill of the project region after the regulation works is calculated and analyzed with the numerical model. The resedimentation of the navigable channel is estimated by the means of combining theories with experiences. It is the supplement of the sediment numerical model. And the results of model and estimation are compared and analyzed. |
