摘要
Abstract
In recent years,the implementation of a series of regulation works including deep-water channel construction at the head of Luochengzhou and its right branch has led to continuous scouring and retreat of the bank line near Fengle Bridge on the right bank of the right branch,even triggering bank collapse.Despite multiple rounds of emergency bank protection projects,the bank collapse has continued to develop slowly.Based on an analysis of the historical evolution of the Luochengzhou distributary channel,this study examines its recent evolutionary characteristics from four aspects:planar morphology changes,diversion ratio variations,river channel adjustments and typical bank segment evolution.It further reveals the impact of river regime on the Luochengzhou distributary channel,and preliminarily forecasts the evolutionary trend of its right branch,which provides a theoretical basis for subsequent engineering construction and the exertion of project benefits.关键词
