As a new type of energy dissipation and beach protection structure，the active hook structure is used for the first time in the first phase of deepwater channel project of the Yangtze River.The structure has a significant effect on promoting sedimentation and anti-scouring. Through the field investigation and sampling and laboratory detection and analysis，the multi-elements of water ecology and water environment around the active hook structure are detected and analyzed. The results show that the active hook structure can improve the habitat of aquatic organisms and biodiversity，and has a good ecological environment effect. The structure has innovative significance for ecological restoration of waterway regulation projects.
