An appropriate formula of bedloadrate is chosen to calculate the amount of bedload of each section. Curves of amount of bed load and discharge are got.
The formulas of velocity distribution, flow resistance and bedload transport rate are obtained, in which the flow and sediment movement are considered simultaneously.
本文还导得动平床情况下的流速分布公式、阻力公式和输沙率公式,使动床的水流运动和输沙过程得以联解。

When the flow intensity is high, the transport rate of bedload as given by Einstein formula might be too small.
