Based on the measured data of Shazhou waterway in the middle reach of the Yangtze River in recent years,we analyze the river bed evolution and navigation-obstructing characteristic of it,and according to the channel regulation planning for the Yangtze River,we propose the channel regulation idea and scheme. Combining with the mathematical model calculation,we carry out the mobile bed research on two regulation schemes.The results show that the two schemes can both guard the beach, control the left branch and stabilize the right branch, and achieve the desired regulation effect.However,scheme one is better,thus it is chosen as the recommended scheme.
