【摘要】Mathematical models of reservoir water temperature were used to analyze the stratification rule of reservoir water temperature and the process of discharge water temperature, which are important means to predict the environmental impact of projects, and manage the quality of reservoir water.Nowadays, there are many mathematical models of reservoir water temperature prediction.However, the domestic applications of reservoir water temperature prediction are mostly based on single model in individual cases.The comparative study on the applicability of different models is very rare.In this paper, five common models of reservoir water temperature prediction were compared, including one vertical one-dimensional model, two vertical two-dimensional models-WWL and CE-QUAL-W2, as well as two three-dimensional models-MIKE3 and EFDC.Based on the measured data of typical lake-like reservoir-Dongjiang and river-like reservoir-Sanbanxi, these models were verified, and the model parameters were calibrated.Based on calculation results, simplifying assumptions, turbulence models and calculation methods of the models, the applicability
