The Three-dimensional Environmental Fluid Dynamics Model for the Water Temperature of Manwan Reservoir
The water temperature prediction has been one of the important contents of the environmental impact assessment on the hydropower projects. The paper summarized the advances in water temperature research for reservoir in china and abroad and studied the structure of the three-dimension environmental fluid dynamics (EFDC) model. Based on hydrological and water temperature data of Manwan Reservoir in Yunnan province, the EFDC model was calibrated for February 2004 and validated for 2003 and January 2004. The calibrated result shows that averaged absolute mean error of the three vertical on front of dam is - 0.15℃ and averaged relative error is approximately 2.0％. The model was verified with a comparison to continuous time series of surface water temperature in front of the dam. The absolute mean error is - 0.36℃, but the model simulations exhibit the same trends as the observations.
