Calculation method of lake-reservoir water temperature and its result analysis
摘要
Abstract
The empirical formula method and mathematical model method for calculating the lake-reservoir water temperature are introduced in detail,and then both the methods are respectively applied to the calculation of the water temperature in the Xiangxi Bay of Three Gorges Reservoir.The results show that the RMSE(root-mean-square error) of temperature compared between the calculated values from the methods of empirical formula and the mathematical model and the measured value are 1.063 ℃ and 0.349 ℃ respectively,thus the precision of the mathematical model is higher than that of the empirical formula,additionally,only the vertical profile of the water temperature can be obtained by the empirical formula as well.However,a hydrodynamic-water temperature coupled mathematical model established herein can comprehensively show the characteristics of the 3-D water temperature distribution in the study area concerned.关键词
