Located in Tsinghua University, State Key Laboratory of Hydroscience and Engineering was established on July 26^th 2006 with approval of the Ministry of Science and Technology of P.R. China, gathering together various elites of hydroscience and engineering research field of the Tsinghua University. It is an experimental laboratory operated under mechanism of “Open, Mobile, United and Competitive”. On June 26^th 2008, the laboratory was inspected and accepted by the Ministry of Science and Technology and honored as the “Best Laboratory” in the National Lab Assessment in 2008 and 2013. Academician of the Chinese Academy of Sciences and Chinese Academy of Engineering Mr. Chen Zuyu serves as the director of the Lab’s Academic Committee and Prof. Li Qingbin serves as the director of the Lab respectively.

Due to the global water deficit, severe water contamination and continuous floods, focus of the international research has shifted to the mechanism of multi-scale water cycle and watershed movement, multipurpose water utilization and watershed management. Therefore, it is of great necessity to carry out the following four strategic programs: river and lake management (mainly Yangtze River and Yellow River); development of the western regions; West-to-East Power Transmission and South-to-North Water Transfer. Importance should also be attached to the ecological effects of large water control projects, design of shockproof water control system with high-dam and big-reservoir, king-size and economical hydro generators with good perance and stability.

With the basis of the traditional subject advantages, the laboratory has set up five research fields, with focus on the international subject frontier and the state demands, including: (1) Hydrology and water resources science. Since the distribution and demand of water conservancy of China are irregular, scientists have carried out researches on water cycle, eco-environment, complex dynamical system, technologies of the water conservancy; prevent of flood and droughts. (2) Water, sediment and environment sciences. Based on researches involving the movement of watershed and the transport process of the pollutants or nutrients，the scientists have been focusing on modeling the hydrodynamics of river and lakes, lands，eco-environment response mechanism, calamity ation. (3) Geomechanics and geotechnical engineering. Studies concerning construction and application of large control projects have been developed considering the structures of the dam foundation, deep slopes and underground group caverns. Moreover, researches have been focusing on nonlinear models for the dynamics of the materials, structural design theories, rock and soil structure, progressive failure of the materials, security evaluation of the structure and reinforcement technologies. (4) Hydro-junction and intelligent management. Research has been developed on the dam structure, static and dynamic properties of the materials under complex loadings, long and short deation process of the high dam and security evaluation methods, materials and structure design theories applied to high dam construction, digital hydro-junction project and smart hydro-junction theory research. (5) Hydrodynamics and hydraulic machinery. Focusing on efficient, stable and economical hydraulic turbine, advanced researches have been evolving the interior flow mechanism of hydraulic machineries, shape optimization technologies, dynamics of mechanical systems and security control technologies.

Based on the five research fields, the laboratory has achieved fruitful results, and invented a series of distinct and innovative equipment for scientific research. (1) With researches on hydrology, water resources and management methods, new evaporation model has been put forward and has explained the evaporation paradox in the international hydrology and water conservancy. Besides, centralized water regulation model system has been constructed and applied to projects of Yellow River and Tarimu River. (2) Based on the water, sediment and environment science, model systems of vegetation-erosion dynamics and water and sediment dynamics have been developed. Based on these systems, delayed response model of progressive change of Yellow River could be quantified and aiming solutions for many key technological problems that were related to decision making during the Three Gorge Project and South-to-North Water Transmission Project. (3) Geomechanics and geotechnical engineering. The multi-scale and nonlinear thermodynamics under the non-equilibrium state of quasi-brittle materials, together with the deation and reinforcement theory of high dams, has successfully solved the problems related with high slope reinforcement. (4) New dam structure. Construction technologies of rock filled concrete dam, new structure of RCC dam and smart concrete have been widely applied to engineering practice. (5) Hydraulic machinery dynamics engineers. The laboratory has independently designed the new interflow pumps that are applied to the South-to-North Water Transmission Project and the hydro-generator of Jiangxia tentative tidal power station project. Both of them have achieved the international advanced level standard.

The research team consists of a number of senior scientists represented by reputed academicians like Zhang Chuhan, middle-aged and young academic leader represented by Professor Wang Guangqian, and young reserved talents who are innovative and represent the majority of the staff, which makes up of an innovative and cooperative team with reasonable age structures. There are 58 employees including 2 academicians, 40 professors, 9 winners of National Science Fund for Distinguished Young Scholars, 6 Yangtze River scholars, 2 doctors and 1 middle-aged and young expert awarded by the State of Council for their excellent achievements, and also one innovative research group national natural science foundation of China.

Leveraging its plat resources and policy support from the Tsinghua University, the laboratory has actively developed national and international researches and academic exchange. Since its foundation in 2006, from 20%-30% of the approved open research topics are derived from foreign countries, and there are around 10 international cooperated projects annually. In addition, about 5 renowned oversea scholars are usually invited annually to the laboratory for exploration of new courses.

Centering on the national strategic goals, strengthen the international influence, and dedicated to the innovation of outstanding application basis, innovation of important engineering technologies, and innovation of independent property rights, the lab provides technological support and trains excellent talents for related sectors as water resource utilization, river and lake control, hydropower exploitation and watershed protection in China.
