摘　　要：针对传统水文学方法模拟平原地区复杂水流精度不高的缺点,构造了水文水力学耦合模型。该模型采用差分算法求解圣维南方程组进行洪水演算,通过水文模型模拟其边界条件,实现水文学模型与水力学模型的耦合,并结合区域连接关系模拟,实现全流域耦合求解。模型应用于曹娥江流域花山至桑盆殿河段洪水模拟,结果表明:计算水位与实测水位吻合良好,具有较高的计算精度。According to the complex flow conditions in plain areas and low precision simulation results applied by traditional hydrolog- ic methods, a Hydrologic-Hydraulic Coupling Model is established. In this model, finite difference algorithm is used to solve Saint- Venant equations for river flood routing, combining hydrologic models to simulate the boundary conditions of flood routing. Thus, the coupling between Hydraulic Model and Hydrologic Model is realized in the whole basin. The model is applied to the flood simula- tion of Huashan to Sangpendian Region in Cao＇e River Basin. Results show that the calculated water levels match well with the meas- ured water levels, the model has a high calculation accuracy.
