The north channel is an important part of the Yangtze estuary waterway, and the focus in the future as well. The north channel was less stable historically, but during the past 10 years, with the implementation of the Yangtze estuary waterway regulation project, New Liuhe bar beach protection project, and Qingcao bar reservoir project, the boundary condition of the north channel turned stable, and the regime stability was enhanced.Based on the regime analysis, we propose the technical scheme for the channel regulation, including Baozhen bar beach protection scheme and double leading dikes plus a spur dike. The mathematic model result shows that the regulation effect is satisfactory. The planned objective for the waterway can be realized with certain dredging measures. The prospect for the development of the north channel is also given.
