摘　　要：分析了流域模拟中常用的水文学方法,基于单一河段和复杂河网水沙数学模型研究成果,研究了流域中水利枢纽上下游的水动力学衔接条件,并采用概化的算例对枢纽上下游进行了水动力学模拟。结果表明,本文方法可用于对各种类型的流域(含枢纽工程、水库、湖泊等)进行水沙数值计算,同时也可宏观控制流域规划工作且检验流域规划方案。Based on analysis of common hydrological methods in river model and former research results of water and sediments numerical model about single reach and complex river system,hydrodynamics linkage conditions between upper and down reaches in hydro project are analyzed,and the corresponding hydrodynamics model is established and validated with the synoptical cases.The results show that the proposed method can be applied to numerical calculation of water and sediment for various river basins,and control river basin planning and verify scheme of river basin planning.
