The main channel bed will scour if sediment amount from tributary debris is less than that the main stream can carry and the river evolution exhibits the characteristic of mountainous rivers.
当支沟泥石流输入主河的泥沙量小于主河的输沙量时，主河河床将下切，并逐渐恢复山区性河流的特征。
The plane two-dimension numerical simulation is used to study the simulation and calculation of the scour in a river whose bed is mostly cracked bedrock at the lower reaches of a spillway.
采用平面二维数值模拟方法，对溢洪道下游河床以破碎基岩为主的河流冲刷进行了模拟计算方法的探讨。
The test results show that the apron can reduce back flow at the dam toe, and the piers can obviously diminish river bed scouring near the scour resistant wall.
试验结果表明：护坦减轻了下游纵向围堰左侧坝趾处的回流淘刷，隔流墩明显减轻了防冲墙附近河床的冲刷，确保了坝基和下游纵向围堰的安全。
