【摘要】：为预测西南地区某水库的水温分布规律,本文以EFDC模型为基础,参考二滩水库、三峡水库和阿海水库等算例的模型参数取值,建立了该水库二维水温模型,对该水库典型平水年水温分布进行预测,分析了该水库水温分层及下泄水温的变化规律。模拟结果表明:(1)典型平水年夏季该水库会出现水温垂向分层现象,其中6月份垂向温差最大达到10℃;(2)水库表层水体温度呈现出季节性的变化规律,日间变化也十分明显,底层水体温度比较稳定,仅随季节更替稍有变化;(3)水库取水口底板高程620 m时,下泄水温与天然水温比较,下降幅度小于0.5℃。
[Abstract]:In order to predict the water temperature distribution of a reservoir in southwest China, based on the EFDC model, a two-dimensional water temperature model for Ertan Reservoir, three Gorges Reservoir and Ahai Reservoir is established. The typical annual water temperature distribution of the reservoir is predicted, and the variation law of the water temperature stratification and drainage temperature of the reservoir is analyzed. The simulation results show that the vertical stratification of water temperature will occur in typical normal water year summer, in which the maximum vertical temperature difference reached 10 鈩，
