水箱模型中“底水”確定方法的探討
發(fā)布時(shí)間:2019-01-04 23:29
【摘要】:針對(duì)水箱模型將底水參數(shù)化的處理方法,考慮到底水的物理意義,提出一種將底水與次雨聯(lián)系起來(lái),利用次雨初損來(lái)確定第一層水箱的底水的方法,但由于壤中流的復(fù)雜性,第二層水箱的底水值仍參數(shù)化,第三層水箱的底水值采用Q_g=αx計(jì)算,并用清江流域水文資料加以檢驗(yàn),所得成果符合規(guī)范要求。
[Abstract]:In view of the parameterized treatment method of bottom water in water tank model, considering the physical meaning of water in the end, a method of connecting bottom water with secondary rain and determining the bottom water of the first layer of water tank by using the initial loss of secondary rain is put forward. However, due to the complexity of the flow in the soil, a method is proposed to determine the bottom water of the first layer of water tank. The bottom water value of the second layer water tank is still parameterized, and the bottom water value of the third layer water tank is calculated by using Q _ S _ g = 偽 _ x, and tested with the hydrological data of Qingjiang River Basin. The results obtained meet the requirements of the specification.
