摘要/Abstract

摘要： 根据收集的若干山区河流交汇河口资料, 分析并得出以下结论: 山区河流交汇河口分布密度低于平原可流; 来水来沙集中于汛期, 从枯水到洪水的变化过程中, 支流流量占的比重越来越大; 交汇河口附近存在江心洲, 其位置与交汇形式、支流入汇位置等有关.这些特性有助于分析其成滩原因, 对今后山区河流河口滩的整治有所助益.

关键词: 交汇河口, 交汇角, 汇流比, 交汇形式, 水沙条件

Abstract: According to the collected data of mountain river confluences, some conclusions are obtained. Distributed density of the mountain river confluences is lower than that of the plain river, Incoming water and sendiment is concent rated at the freshest period, the change from the low flow to the flood flow. The ratio of tributary discharge is increased; there are river islands near the junction, and the postion of the junction is concerned to the confluent patten and the position of the tributary junction, etc. These properties are helpful for the genetic analysis and the regulation of the shoal at a tributary mouth.

Key words: confluence, confluent angle, confluent ratio, confluent patten, water-sediment condition
