2) Channel scouring and siltation
河道冲淤
1.
Compared with the research of channel scouring and siltation for a long period, the research of recent channel evolvement from 1950s is more significative to prevent flood, to exploit channel, and to plan port and so on.
与长时间段的河床冲淤平衡研究相比，近期河道冲淤(从20世纪50年代至今)的研究对长江下游的防洪、航道的开发、港口的布局等更具有实践意义。
3) erodible-bed channel
冲淤河道
1.
There are a lot of factors that work on the water level of erodible-bed channel together, each of them varies no role, but is correlative.
冲淤河道水位受到很多因素的共同作用，各因素本身的变化没有规律且互相关联，相邻前后年份或同一场洪水的不同洪峰前后，影响水位的水、沙、河道等因素常差别很大，水位与其影响因素之间客观上是非线性关系。
5) amounts of channel scour and fill
河道冲淤量
1.
The difference method of sediment discharge is one of the main methods for calculating the amounts of channel scour and fill.
输沙量差法是计算河道冲淤量的主要方法之一。
6) scouring and silting channel
冲淤性河道
1.
The lower reaches of the YelowRiver belong to scouring and silting channel, because of water-sedimentraiting curve , channel s boundary and their interaction, the changing process of stage is complexity, stage s fluctuation is often quite great in the almost same runoff.
黄河下游属于冲淤性河道，由于水沙条件、河道边界等因素及这些因素的相互作用，水位过程特征线非常复杂，同流量下的水位变幅很大。
