浅析流速垂线分布与含沙量垂线分布的关系
Analysis of the relationship between vertical distribution of velocity and vertical distribution of suspended sediment concentration
摘要
Abstract
According to the formula structure, the vertical distribution formulas of velocity are classified into 3 types. Then the vertical distribution formulas of sediment concentration corresponding to the 3 types of velocity formulas are deduced. The theoret-ical study result shows that the relationship between velocity and sediment concentration is close to the relationship between veloc-ity gradient and sediment concentration gradient, on this basis, the vertical distribution formula with velocity variable correspond-ing to each velocity formula is deduced. And the influence of 3 types of velocity distributions on sediment distribution is dis-cussed. It is concluded that the quantitative relation of velocity magnitude and sediment concentration magnitude is exponential one.关键词
