Daijiazhou Waterway is located in the middle reaches of the Yangtze River from Wuhan to Anqing，and it is one of the key beach sections that affect navigation in the branches of the middle reaches of the Yangtze River.In recent years，as the economy develops along the Yangtze River，higher requirements have also been placed on the water depth of the waterway.To meet the higher-scale water depth requirements，the waterway department implemented the 6.0 m waterway regulation project for the waterway in 2018.After the implementation of the project，regular observation data of effects is analyzed to evaluate the remediation effects.The results show that the implementation restrains the continuous scouring development of the Chihu Port Beach and the Lejia Bay Beach.It constructs a good beach-groove pattern and improves the waterway conditions of the straight channel，basically unblocking the 6.0 m channel.
