摘　　要：建立了反映顺坡面串、汇流特点的平面二维水动力数学模型,对河南省大沙河串流区在南水北调工程总干渠修建前、后的洪水传播进行了数值模拟.根据数值计算结果做出的修改方案,可以改善总干渠左岸局部积水淹没严重的状况.A 2-D hydrodynamic mathematic model which shows characteristics of furcation and conflux flow on slopes is developed. The flood transmission in the furcating flow area of Dasha River, Henan Province, before and after the construction of the main canal of the South-to-North Water Transfer Project is numerically simulated. The improved scheme according to the numerical calculation results can effectively reduce the local submergence in the left bank of the main canal.
