Recently, NHRI, together with Water Conservancy Bureau of Hinggan League, jointly hosted the On-site Demonstration Meeting for Achievements of National Key R&D Program Project R&D of Technologies and Equipment for Overtopping and Breach Prevention of Embankment Dams of Small and Medium-sized Reservoirs under Extreme Floods and Inner Mongolia Autonomous Region Technical Exchange Conference on Reservoir Dam Safety Management in the Hinggan League. Centering on the needs for improving engineering resilience and emergency rescue of embankment dams of small and medium-sized reservoirs against extreme floods, the events featured on-site demonstration of project achievements and technical exchanges on reservoir dam safety management. Representatives from reservoir construction and operation management entities, research institutes, universities, enterprises and participating institutions of the project attended the meeting.

During the on-site demonstration session on the afternoon of October 9, participants visited the Xing’an Reservoir. They observed relevant technical achievements and equipment covering water retaining, flood discharge, dam surface protection, monitoring and detection, and emergency rescue. Live demonstrations including unmanned surface vehicle operations, mechanized laying of the “Dam Raincoat” and dam slope scouring tests were presented. Discussions were held in light of the requirements of engineering management and flood control emergency rescue.

Inner Mongolia Autonomous Region Technical Exchange Conference on Reservoir Dam Safety Management

On the morning of October 10, special technical exchanges on reservoir dam safety management in Inner Mongolia Autonomous Region were carried out. Relevant leaders from Water Resources Department of Inner Mongolia Autonomous Region and Water Conservancy Bureau of Hinggan League delivered addresses. The project principal of NHRI chaired the session and spoke on behalf of the project lead institution. SHENG Jinbao, Chief Engineer of Dam Safety Management Center of the Ministry of Water Resources, gave a special report entitled Reflections on Renovation and Upgrading Technologies for Aging Reservoirs. ZHANG Lirong, former Chief Engineer of China Anneng Group, delivered a special report entitled Key Technologies for Emergency Response to Reservoir Dam Hazards. An unveiling ceremony for the Project Demonstration and Application Base was held during the meeting. The Base will serve as a practical platform for engineering verification, demonstration application and technical exchange of technologies and equipment for overtopping and breach prevention.
