摘要/Abstract

摘要： 河床形态的变化是揭示浅滩冲淤特性和演变规律的重要因素。本文基于自然动床模型试验成果和天然河流实测资料的分析，论述了河床纵断面和横断面形态以及滩面垂向变率与浅滩演变的关系，同时，对河床形态影响浅滩演变的内在机理进行了探讨．

关键词: 床面形态, 浅滩演变, 冲淤变幅

Abstract: Based on the model test and the field-data analysis of pool-riffle seqnences in meandering streams, the charaeteristicsof bed-forms and mechanism of shoal bars have been imestigated and discussed in the paper. The results of thses stud-ies show dirrerent
