Ouchikou waterway is one of the key navigation obstructions in the middle Yangtze River.This paper analyzes the recent morphological evolution and navigation obstructing characteristics of this waterway.Combining with the project construction aim and standards，this paper proposes the plane layout of the project.A combination of shoal protection belt and revetment is chosen as the project structure based on the comparison of existing navigation structures which are applied to the waterway regulation.Also，the project structures are designed to adopt new structures，which may serve as reference for the similar waterway regulation design.
