长江澄通河段通州沙西水道整治工程对分流比影响研究
Research on influence of regulation works on diversion ratio of Tongzhousha west channel in Chengtong reach, Yangtze River
摘要
Abstract
The regulation works for Tongzhousha west channel,including the point-bar reclamation,submerged breakwaters and dredging works,were conducted for the sake of enriching the coastline resources from deep water.The different diversion ratios of the branch channels were simulated and calculated before and after the regulation plan with one-dimensional and two-dimensional coupling wave-current model to analyze the influence of regulation works on Tongzhousha reach.Results indicate that the point-bar reclamation,submerged breakwaters,dredging constructions and upstream runoff conditions,etc.have an effect on the diversion ratio.Specifically,the diversion ratio of Tongzhousha west channel will be reduced by point-bar reclamation and submerged breakwaters,while it will be increased by the dredging works.The variation degree of the diversion ratio after the regulation works mainly depends on the dredging depth of west channel.Therefore,the dredging scale should be considered cautiously for the maintenance of the stability of the river regime.关键词
