Qichun waterway regulation project is a preliminary task of the 6 m deep channel project in the Wuhan-Anqing section of the mainline of the Yangtze River. In recent years，the evolution characteristics of riverbeds in the Qichun waterway generally lead to shallow areas at the entrance of bends. Meanwhile，as erosion ditches and right channels in the head of the Lijiazhou side shoal develop rapidly，channel conditions tend to be worse. In order to curb the adverse waterway development，the waterway regulation project started in 2017. After the completion of the project，this paper comprehensively analyzed the changes in waterway and channel conditions based on the measured data before and after the project. The result reveals that after the implementation of the regulation project，the Lijiazhou side shoal gets protected，and the hydrodynamic force in shallow areas improves. The high shoreline in the key position is stable，and the adverse change trend of channel conditions has been basically restrained. As a result，the construction goal is achieved，with positive project effects.
