摘要/Abstract

摘要： 通过一系列的水槽试验，研究了交汇角为30°时不同水沙条件下干流床面冲淤特性，获得了在支流有无来水、来沙时不同主支汇流比下的干流床面冲淤二维等值线图，初步揭示了干流床面冲淤随主支流量比及支流是否来沙的变化特性。研究成果对了解交汇区的冲淤变化及河床演变具有积极的作用。

Abstract: There are complex interrelationships and internal mechanisms among bed form, sediment transport and flow structure in natural river , in particular in confluent river. The experiments were conducted in flume including different cases, e.g., without branch flow, branch flow with clear - water， branch flow with both water and sediment. The stable bed morphology in every case was measured and analyzed with different discharge ratios q* of the branch channel flow Qb to combined tail - water flow Qt. The characteristics of variation of bed morphology of main channel under above - mentioned cases were revealed. 
