| 摘 要： | 采用基于准确Riemann解的Godunov格式,求解包括底坡项的二维浅水流动方程,应用WLF(water level-bottom topogra-phy formulation)方法求解Riemann解。经实测涌潮资料验证,较好地模拟了钱塘江涌潮的发生、发展及其衰减的过程,复演了涌潮的相交、反射和一线潮等现象,对钱塘江涌潮宏观规律的认识有所加深。

| Abstract: | 2D shallow-water equations with bottom topography are solved by Godunov-type scheme based on the exact Riemann solution,which is gotten by using WLF(Water Level-Bottom Topography Formulation).The mathematical model is applied to simulate the formation,evolution and dissipation of the tidal bore in the Qiantang River.A good agreement is made between the computed and field measurements,and it also numerically replicates the phenomena of the intersecting,reflection of the tidal bores,and line-type tidal bore,which leads to more understanding about the tidal bores in the Qiantang River. |
