bed load transport

基本解释

Rule of bed load transport in tidal reach of the Yangtze River and distributing rule along the river are studied.
研究长江感潮河段推移质输移规律和沿程分布规律。
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。
Study on bed load in tidal reach of the Yangtze River is not enough. Estuary is more researched. So the rule of bed load transport in reach from Datong to Xuliujing is not realized well.
长江感潮河段的推移质研究工作较少，主要集中在河口地区，而对大通至徐六泾河段的推移质输移规律了解欠缺。
