Analysis of Causes for Navigation-Obstruction in Wuqiao Waterway in Middle Reach of Changjiang River and Proposal of Schemes for Regulation and Control

Wuqiao Waterway runs through Wuhan City, which lies in the middle reach of the Changjiang River. In dry seasons, the Hanyang Shoal will extend to the navigational channel in the center of the river, making the waterway twist and turn and causing obstruction to the navigation, thus making it more difficult to maintain the navigational channel. The paper describes briefly the characteristics in riverbed evolution in this section of waterway and the causes to navigation obstruction, analyzes the main factors affecting the scouring and silting in the Hanyang Shoal, and proposes a preliminary plan for regulation and control of this section of waterway.
