河床结构强度及其与水流能量关系的定量研究
Quantified study on the riverbed structure intensity and its relationship with stream power
摘要
Abstract
Streambed structures were developed in many mountain rivers as a result of fluvial morphology and their distributions were relevant with environmental conditions.This paper used a new accurate method and studied the distributions of such structures based on the field data of natural rivers.The results indicate that for a river in dynamic equilibrium,the intensity Sp of its streambed structures is proportional to its unit width stream power p consumed by the structures.This means that the distributions are relevant to hydraulic conditions.If the structures are not able to consume up the total power p,the river is in non-equilibrium status and its excess power will cause erosion of streambed.The unified power consumption model including bedload movement was also discussed in this paper.关键词
