In recent years,due to the influence of clear water discharge from the Three Gorges Dam,the change of Shazhou waterway is not conducive to navigation.According to the management planning and navigation requirements for the Yangtze River waterway,the field data of Shazhou waterway were analyzed and the regulation idea for Shazhou waterway was put forward.Furthermore,a series of the fixed-bed model tests were carried out to analyze the influence of different schemes on the division ratio of left branch,and the movable-bed model test was carried out by selecting the scheme with better flow structure.Through the typical annual movable-bed model test,the riverbed erosion and deposition,local scour,etc.were analyzed,and the recommended schemes for Shazhou waterway regulation were determined:3 beach protection belts with hook heads were arranged at the beach head of the heart of Huangzhou shoal,2 extended latent locking dams were arranged in the left branch,and the height of lock dam crest was 4.59 m.Relevant achievements can provide technical support for engineering practice.
