The river bed in the middle reaches of the Yangtze River is mostly sandy，and the river bed evolution is violent，which is controlled by the nodes of rocky mountains，rock spurs and artificial revetment projects on both banks.The evolution of the upper and lower reaches has obvious relevance features.Taking the Mu’ezhou channel as an example，we analyze its evolution characteristics and relevance features with the downstream Huguang channel.Considering the adverse change trend of the current channel and the implemented channel regulation project，we study the regulation scheme of the associated evolution reach.The implementation of the beach protection project in the Mu’ezhou channel addresses the lower and medium beaches scouring in the Mu’ezhou beach and the shallowing in Wangjiapu of the Huguang channel.Adopting a mathematical model and a physical model，we verify the effect of the scheme with post-flood observation data since 2020.The results show that after the scheme implementation，the scouring of Mu’ezhou beach is effectively controlled，and the shoal channel pattern turns stable.Moreover，the channel width of 6 m water depth basically meets planning requirements.
