【摘要】:為預(yù)測西南地區(qū)某水庫的水溫分布規(guī)律,本文以EFDC模型為基礎(chǔ),參考二灘水庫、三峽水庫和阿海水庫等算例的模型參數(shù)取值,建立了該水庫二維水溫模型,對該水庫典型平水年水溫分布進行預(yù)測,分析了該水庫水溫分層及下泄水溫的變化規(guī)律。模擬結(jié)果表明:(1)典型平水年夏季該水庫會出現(xiàn)水溫垂向分層現(xiàn)象,其中6月份垂向溫差最大達到10℃;(2)水庫表層水體溫度呈現(xiàn)出季節(jié)性的變化規(guī)律,日間變化也十分明顯,底層水體溫度比較穩(wěn)定,僅隨季節(jié)更替稍有變化;(3)水庫取水口底板高程620 m時,下泄水溫與天然水溫比較,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,
