1) sediment exchange
泥沙交换
1.
On the basis of mechanism of sediment exchange,some improvements in relation to the calculation method for riverbed deformation are performed,including modification of dispersion equation of suspended load under the condition of erosion;definition of carrying capacity of non uniform sediment;definition of efficient transport rate of bed load as well as that of time step and space step.
根据泥沙交换原理 ,对河床变形计算方法进行了若干改进。
2) sediment lateral exchange
泥沙横向交换
1.
The productive embankments on the watercourse bottomland disturb the water-sediment lateral exchange between bottomland and main flume,which have great influence on the riverbed evolution.
河道主槽两侧修建的生产堤影响滩槽泥沙横向交换,对河床演变带来很大影响。
3) exchange between coarse and fine sediments
粗细泥沙交换
4) sediment exchange between flat and pool
滩槽泥沙交换
5) coefficient of momentum transfer and sediment transfer
动量交换和泥沙交换系数
6) water and sediment exchange
水沙交换
1.
Firstly, the dynamical mechanism of water and sediment exchange and transport between Changjiang E.
本文以长江口与杭州湾交汇地带的南汇边滩为研究对象，在充分借鉴前人研究的基础上，采用水文学、泥沙运动力学和数理统计等方法，对长江口与杭州湾水沙交换的动力机制和输移特征以及南汇边滩的水动力、泥沙输移进行了深入系统的研究。
2.
Nanhui tidal flat located in the joint area between the Yangtze Estuary and Hangzhou Bay is an important way for water and sediment exchange between the Yangtze Estuary and Hangzhou Bay.
南汇东滩位于长江口与杭州湾的交汇处,是长江口与杭州湾水沙交换的重要通道,文章结合水动力特征指出南汇东滩是长江口外一个特殊的潮流动能减弱区,潮滩南北两侧潮流动能相对较强,涨落潮时过境泥沙易于落淤。
