| Abstract: |
| Based on the complex geometrical condition of a natural river and the design scheme of a port project,a 3-D numerical simulation model for the project reach is developed.The control equation group is discretized by adapting the finite volume method,and the variation of the flow field of the project reach is predicted by using the coupled multigrid with full implicit scheme. |
