水箱模型中“底水”确定方法的探讨
发布时间:2019-01-04 23:29
【摘要】:针对水箱模型将底水参数化的处理方法,考虑到底水的物理意义,提出一种将底水与次雨联系起来,利用次雨初损来确定第一层水箱的底水的方法,但由于壤中流的复杂性,第二层水箱的底水值仍参数化,第三层水箱的底水值采用Q_g=αx计算,并用清江流域水文资料加以检验,所得成果符合规范要求。
[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 = 伪 _ x, and tested with the hydrological data of Qingjiang River Basin. The results obtained meet the requirements of the specification.
