1. Watershed flood model and its application.
Based on the comparison of the series coupling models of hydrology and hydrodynamics and the dynamic unidirectional coupling between hydrological model and one-dimensional hydrodynamic model at home and abroad, a DBCM (Dynamic Bidirectional Coupling Model) direct Dynamic Coupling Model is being established for flood and waterlogging prediction ( refer to: NAT. Hazards Earth Syst. Sci., 21, 497-515).
It is the direct dynamic bidirectional coupling between the distributed hydrological model and the two-dimensional hydrodynamics. The spatial conservation discrete scheme is adopted to ensure the conservation of water and momentum through the coupled dynamic boundary. The explicit time scheme is adopted to make the model have better computational efficiency. The computational efficiency of the model is further improved by multi-grid technology.
2. Watershed environment model and its application
Based on the comparison of the existing land model and water model integration or series coupling, a watershed water environment model based on DBCM is proposed. The land model and water model are dynamically coupled, which belongs to full coupling model or mechanism coupling model. The proposed model will keep good accuracy and improved computational efficiency.
National Key Basic Research Program of China. 973 Program Program. Water ecological process, waterenvironmental effects and ecological safety regulation of wetlands in Huang-Huai-Hai region. Through the cooperation with the Ministry of Water Resources and the China Three Gorges Corporation, we have carried out long-term research on the water environment characteristics of the Three Gorges Reservoir, simulated and predicted the change trend of water level and water environment before and after the construction of the major river sections in the Three Gorges Reservoir area, and undertaken several major scientific research projects.
3. Computational Fluid Mechanics
A mult-step finite element method based on the Taylor expansion is proposed, which has the advantages of good numerical stability and high calculation precision.
