As an important navigable reach of the middle and lower reaches of Hanjiang River,after the implementation of Danjiangkou Reservoir and the Yangtze River to Hanjiang River water diversion project,the upstream water duration and discharge have undergone great changes,and the changes of water flow,sediment movement and riverbed are very complicated.This paper studies the regulation plan of Goutou Bay based on the measured hydrology,topographic data in recent years and model test data,it focuses on the analysis of the evolution characteristics of the shoal section,the relationship between water flow and sediment movement and the characteristics of navigation-obstructing and proposes the regulation project.The verification results show that the implementation of the regulation project stabilizes the project reach beach,narrows the width of the middle and low water river,the deep trough is generally scoured and tends to be stable,and the middle and low water river regime can be effectively controlled and consolidated.The research results can provide reference channel regulation of Goutou Bay section shoal and similar channel section.
