摘　　要：本文研究了牤牛河典型洪水以及大凌河、牤牛河发生洪水遭遇时,牤牛河口交汇区泥沙淤积形态及其分布。试验结果表明:牤牛河发生洪水时,交汇区的淤积较大;大凌河洪水先于牤牛河洪水发生时,牤牛河交汇区的泥沙淤积大于牤牛河洪水先于大凌河洪水发生;当稀遇洪水遭遇时,交汇区的淤积量很少,泥沙基本被带往交汇区下游。从动力学角度分析,牤牛河泥沙淤积是必然的。The paper studies the typical floods of the Mangniuhe river and the sediment deposition morphology and its distribution in the estuary intersection area of Mangniuhe river when the floods occur in the Dalinghe and Mangniuhe rivers. The test results show that the deposition of the intersection area is large when the flood occurs in the Mangniuhe river. When the flood of Dalinghe river occurs earlier than the flood of the Mangniuhe river,the sediment deposition in the estuary intersection area is more than coming earlier of Mangniuhe river flood.When the very unexpected flood occurs, the deposition quantity is seldom, then the sediment are carried basically to the downstream of the intersection area. From the point of view of dynamics, the sediment deposition is inevitable in Mangniuhe river.
