Smart Watershed Research Centre

Research Center Orientation

In response to the major national strategic requirements for the protection of the Yangtze River, the Center is dedicated to addressing the fundamental theories of river basin water systems and confronting the scientific challenges in water disaster, water resources, and water environment practices amid socio-economic development. The Center undertakes fundamental and applied research in river basin eco-hydrology, water resources, and water environment. Furthermore, it endeavors to develop, integrate, and demonstrate intelligent river basin systems. A comprehensive simulation and decision support system anchored by a basin water system simulator has been established. The endeavors of the Center contribute to technological support for disaster prediction, water resource management, and ecological protection in the upper reaches of the Yangtze River and the Three Gorges reservoir area.


Research Direction

The team's research revolves around the theme of Smart River Basin. Based on basin water system theory and integrated with artificial intelligence and other technologies, the research scope covers the monitoring, regulation, simulation and integration of basin water cycle process and core elements.


1. The team members conduct fundamental research on the coupling and decoupling of natural water cycle and its accompanying processes in river basins. The processes of natural water cycle precipitation, evapotranspiration, runoff generation and confluence, as well as the transformation of plant water, groundwater, atmospheric water, surface water and soil water are studied. The systematic processes of river basin ecology, hydrology, water resources and water environment at different scales are investigated. The mechanism of interaction between human activities and the natural water cycle is also being analyzed.


2. The integrated simulation technology of river basin water system is an important research direction. This direction covers the comprehensive simulation of hydrology, water resources, water dynamics, and water environment, etc. Different simulation scales, steps and elements can be setted according to the characteristics of river basins. The integrated simulation technology of meteorology, hydrology, ecology and disaster has been developed, which can provide support for analyzing the trend of river basin water system factors and the comprehensive control under the changing environment.


3. Derived from the natural water cycle, the influence of human activities on the cycle process is considered, and the relationship between regional economic development and ecological environment protection is investigated. The thoughtful water system scheduling and regulation strategies are studied for the sustainable development of river basin. The sustainable utilization of water resources, the protection of water ecological environment and the green development of regional economic can be realized according to these research findings.


4. In order to satisfy the construction of digital twin basin, professional platforms fouced on basin water system simulation have been developed based on advanced technologies such as artificial intelligence, big data and cloud computing, etc. Some examples, such as Yangtze River Basin, etc, have been complished and applied in practice.
