摘　　要：河道水流模拟和河床冲淤计算是河流模拟中经常遇到的问题。FST2DH模型是比较适用于水动力和泥沙计算的二维模型,对局部水工构筑物附近水流和泥沙运动的模拟更具优势,河流桥墩附近的水流模拟实例也说明该模型是方便和有效的。The simulation of water flow and scour ＆ deposition are the key points of the hydraulic numerical simulation.The modeling of FST2DH is adapted well to the two - dimensional depth - averaged surface water flow and the non - cohesive sediment transportation, especially for simulation of that around hydraulic structure. The advantage of FST2DH is shown by the test about the numerical simulation of water flow around the pier.
