Notice on Accepting Applications for the 2026 Open Research Projects of the State Key Laboratory of Hydraulics and Mountain River Engineering
The State Key Laboratory of Hydraulics and Mountain River Engineering at Sichuan University traces its origins to the National Key Laboratory of High-Speed Hydraulics, which was approved for establishment by China’s State Planning Commission in May 1988. It passed its formal acceptance inspection in 1992 and opened to researchers in China and abroad. It was the first state key laboratory in China in the fields of water conservancy, hydropower, and river engineering. On March 28, 2023, the National Key Laboratory of Hydraulics and Mountain River Development and Protection was approved to be reorganized as the State Key Laboratory of Hydraulics and Mountain River Engineering (hereinafter referred to as the “Laboratory”). Since its establishment, the Laboratory has focused on applied basic research. Its primary mission is to address major national needs by researching and applying modern theories and methods in water science and technology, and by solving major scientific and technical challenges in water conservancy and hydropower projects.
To promote open collaboration and academic innovation, bring together leading research teams from China and abroad, and jointly address key scientific questions and technical bottlenecks in mountain river protection, channel evolution and management, and disaster prevention and control, the Laboratory has established an Open Research Fund.
