| Abstract: | In order to analyze the impact of new Zhouhe Bridge to the hydrodynamic characteristics of this river reach,the unsteady flow two-dimension hydrodynamic model is developed.The flow condition of the river reach after the bridge's finish is simulated and the change of the river reach flow field before and after bridge's finish is analyzed.The result shows that the change of the river reach flow field is quite small and the flow conditions are quite ideal after the bridge is built. |
