一、河相关系研究的回顾 由于河道整治与规划的需要,稳定河床断面的河相关系,自1924年苏联国立水文研究所格鲁什科夫提出天然河流不可能无限窄深,也不可能无限宽浅,宽度与深度之间必然存在一定关系以来,许多学者从不同的概念出发,得出了各自的河相关系式。可以认为,各种类型的河相形态方程式,在一般情况下,其变量不外乎水深h(或水力半径R)、河宽B(或湿周X)、河床比降J,流速u、流量Q、含沙量
I. Review of the study of river facies Due to the need of river regulation and planning and the stability of the river system of the riverbed section, since 1924, Groushkov proposed that the natural rivers of the Soviet National Hydrographic Institute can not be infinitely narrow and deep, nor infinitely shallow , There is bound to be a certain relationship between width and depth, many scholars from different concepts, come to their own river-related. It can be considered that the morphological equations of various types of rivers are generally nothing more than water depth h (or hydraulic radius R), river width B (or wet week X), river bed ratio J, flow rate u, flow rate Q , Sediment content
