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.
河道水流模擬和河床遲淤計算是河流模擬中經常遇到的問題.FST2DH模型是比較適用于水動力和泥沙計算的二維模型,對跼部水工構築物附近水流和泥沙運動的模擬更具優勢,河流橋墩附近的水流模擬實例也說明該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 the numerical simulation of water flow around the pier.
