| Abstract: | The basic equations of 2 D sediment mathematical model, boundary conditions in the boundary fitting orthogonal coordinate system,the moveable boundary technique and the numerical solution are firstly introduced.The model is then verified with the data of flow and sediment of the down stream of the Beijiang River in Guangdong. In addition,the animated drawing of the velocity field is initially studied with Visual Basic 5 0 The unresolved problems are discussed. |
