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.
研究長江感潮河段推移質輸移槼律和沿程分佈槼律。
The formulas of velocity distribution, flow resistance and bed load transport rate are obtained, in which the flow and sediment movement are considered simultaneously.
本文還導得動平牀情況下的流速分佈公式、阻力公式和輸沙率公式，使動牀的水流運動和輸沙過程得以聯解。
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.
長江感潮河段的推移質研究工作較少，主要集中在河口地區，而對大通至徐六涇河段的推移質輸移槼律了解欠缺。
