| Abstract: |
| Unstructured finite-volume numerical algorithm was presented for solution of two-dimensional shallow water equations,which based on the Roe type approximate Riemann solver to the interface flux.The MUSCL and two-step Runge-Kutta were used to get high order scheme in spatial and time,respectively.Characteristics decomposition methods used to the slope source terms and semi-implicit method used to the friction source terms kept the scheme stability and harmonious.The drop test presents that this model is high resolution,high order and well for the wetting/dry interface.The model was also used to the PanTouPao detention basin to simulate the flood of 1998. |
