Laohuliang Beach in the upper Yangtze River is a major navigation-obstructing shoal from Chongqing to Yichang reach.Several marine accidents have occurred recently，which seriously affect the safety of navigation and shipping efficiency.In view of the above problems，this paper performs a physical model test and a ship model test.On the basis of deeply revealing the navigation-obstructing flow characteristics and navigation safety problems of Laohuliang Beach，the paper compares and studies the flow conditions and navigation states after the implementation of different channel regulation schemes.The results show that the schemes can reduce the influence of bad flow patterns on the safe navigation of ships.After comprehensive comparison，the optimal scheme is put forward，which provides a scientific basis for the design of channel regulation projects on this beach and can be used as a reference for other similar channel regulation research.
