【Abstract】 An equation for the critical discharge between scour ing and filling in alluvial rivers was derived through the theory of non|equili brium sediment transport.The critical discharge between scouring and filling can be thus calculated.It is shown that the critical discharge between scouring and filling mainly depends on the sediment content,the proportional relationship be tween water and sediment,and the boundary condition.更多还原
