摘要
基于矢通量分裂得到了一维浅水方程组的隐式守恒有限差分格式，并对有底坡、有摩阻的梯级水库同时溃坝和相继溃坝的溃坝波传播进行了数值模拟。对数值结果作了分析。结果合理，方法有效可行。
Based on flux vector splitting, a conservative and implicit defference scheme is presented for one dimensional shallow discontinuous water equations with arbitrary cross section. Numerical simulation has been done for the dam break problems in the cascade reservoirs with bed stope and friction when the dams are broken at the same time and in succession. Numerical results are discussed. The results are reasonable and show that the method is efficient and feasible.
