| 摘 要： | 采用基于准确Riemann解的Godunov格式求解浅水流动方程，将仅适用于平底的干底Riemann解推广到处理非平底动边界问题．在计算干底溃坝波的基础上，将该方法应用到有大片滩地的钱塘江河口涌潮计算中，能较好地模拟钱塘江涌潮在滩地上的传播过程．

| Abstract: | The Godunov scheme with an exact Riemann solution is used to solve the shallow water equations, and the classical Riemann solution on dry flat bed is improved to be suitable to the moving boundary with non-flat bed. Based on the verification of a dam-break wave on dry bed, the mathematical model is applied to calculate the tidal bore on the flat alluvial plain of the Qiantang Estuary with the improved Riemann solution on dry bed to solve the moving boundary. Calculation results show that the method can well simulate the propagation of the tidal bore. |
