Jiayu-Yanziwo section is a key navigation-obstructing shallow section emerging in the middle reach of the Yangtze River, and it is of great importance to regulate this part of section for the smooth navigation in the middle reach of the Yangtze River. The main purpose of the project is to protect the bottomland and stable the waterway. The project adopts the beach protection structure, which is built on the head of the bottomland to prevent scouring. After the implementation of the project, the situation of the river course becomes more stable, the deposit occurs at the Fuxingzhou point bar, and the bar widens, the Yanziwo beach becomes stable, thus the waterway is stable, the flow concentrates easily in the low water, the shallow ridge is scoured efficiently, and the degree of navigation-obstructing is relieved. It is thought that the effect of the channel regulation project will become more obvious along with the implementation of the structures’ functions and expected goal will be reached.
