Waterway Regulation Scheme in Daijiazhou Reach of Yangtze River

Abstract

Due to complicated riverbed evolution and numerous navigation-hampering shoals, Daijiazhou reach is the main navigation-hampering channel in the middle Yangtze River for a long time, so it is the key and difficult point for the waterway dimension improvement in the middle and lower Yangzte River. Based on the demand of 6m navigable depth and the research on navigation conditions of Dajiazhou, this paper summarize the characteristics of the navigation-hampering shoals, organizes the regulation thoughts of “improve the bank and shoals protection, partially adjust the morphologies of floodplain and channel†and proposes the detailed solutions.
