Abstract
As the existing researches on the one-dimensional vertical water temperature model lacks systematic sensitivity analysis of key parameters and boundary conditions, with Dongjiang Reservoir as a case, this paper studies the applicability of one-dimensional vertical water temperature model in water temperature simulation of lake-like reservoirs.The research results show that the thermocline changes are mainly controlled by meteorological conditions and the temperature of the water discharge process is stable.The model can well simulate the characteristics of vertical water temperature stratification evolution and the temperature variation in the water discharge, and the simulation results coincide with the observed data.The surface water temperature calculation is relatively sensitive to the moisture thermal flux;and the vertical diffusion coefficient is a critical parameter influencing the simulation of the vertical water temperature.Besides, the meteorological boundary conditions of different accuracy series do not change the total heat budget of the reservoir and have no influence on the water temperature structure.关键词
