本文研究了符合于多沙河流洪水演进的计算方法.黄河流域干支流上汛期最大含沙量高达1000kg/m~3以上.汛期洪水在河道里既有水量调蓄作用,也有沙量调蓄作用.河床泥沙的大量淤积或冲刷,直接影响到河段的出流量.因此马斯京干洪水演进计算方法只能适用于清水河流.本文通过水沙量平衡方程式推导得修正流量的含沙率,并修正了马斯京干洪水演进公式. This paper studies the calculation method in accordance with the flood evolution of the Dousha River.The maximum sediment concentration in the upper reaches of the Yellow River basin during the flood season is as high as 1000 kg / m 3 or more.The flood in the flood season has both water storage and storage functions The large sedimentation or erosion of the river bed directly affects the outflow of the river reach, therefore, the calculation method of Muskingham flood can only be applied to Qingshui River.Through the correction equation of sediment yield and sediment, , And revised Muskingham flood evolution formula.
