Based on sediment transport experiments, the interaction between flow and sediment movement is analysed and the problems of grain resistance and bed load transport on plane movable bed are discussed.
本文在输沙实验的基础上，从研究水流结构着手，分析了水流和泥沙之间的相互作用关系，讨论了动床沙粒阻力和底沙输移规律。
The formulas of velocity distribution, flow resistance and bed load 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。
Based on the study of sediment transport under the actions of tidal currents and wind waves a mathematical model of suspended load and bed load for Yangtze estuary is developed.
