After the implementation of Danjiangkou water diversion scheme, the coming water and sand in the lower Hanjiang river will change a lot, and the shoal will be influenced greatly due to the reduction of scouring during the drop period. Under natural conditions, the shoal can’t be scoured well in the dry season, and the small size of the turning radius can’t meet the bidirectional navigation requirements of the design fleets. This paper analyzes the river bed evolution characteristics and navigation obstruction features, and determines different regulation principles and regulation methods for different shoals. Based on the physical model experiment and self-propelled ship model test, this paper studies the engineering scheme satisfying the ships’ bidirectional navigation, which may serve as a reference for similar shoal regulation.
