黄河河相关系一个突出的特点及其机理初探
A prominent characteristic of hydraulic geometry relation in Yellow River and its preliminary study
摘要
Abstract
This study explores a phenomenon in geohydrology where“the cross section area of a river is ap⁃proximately equal at the same discharge.”This state exists in Wubao, Liuyuankou and downstream from Gaocun in China, and is a prominent characteristic of Yellow River hydrology. Unfortunately, its physical implications are not well understood. This paper considers the relationship between river depth and width, and suspended load transport. Our theoretical analysis uses the equation of continuity of flow, equation of motion of flow, and the equilibrium equa⁃tion of sediment transportation, together with the assumption the“the relative mobility of the bed is the minimum when the sediment transports balance.”Moreover, the hydrological characteristic mentioned above is not present throughout the Yellow River. It appears to only exist in the areas suspended loads and where settlement occurs dur⁃ing transition.关键词
