The characteristics of water temperature and hydrodynamic field in Xiangxi Bay of Three Gorges Reservoir are studied by numerical simulation method. The result shows that the lifting of water level wakened the density current intensity and the vertical mixing of water, and increased the temperature difference between the surface and bottom water. Simultaneously, the dropping of water level enhanced the density current intensity and the vertical mixing of water, and decreased the temperature difference between the surface and bottom water. The numerical modeling is a valid tool in the prediction of the hydrodynamic field in estuary, as a valuable tool in understanding the development and progression of density currents and the influence of scheduling on the hydrodynamic characteristics in the Xiangxi Bay of the Three Gorges Reservoir, therefore, this work could provide helpful supports for nutrient transportation and ecological environmental evaluation. |
