水箱模型中“底水”确定方法的探讨

Research on the Determination of the Bottom Water of the Water-tank Model

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。

This paper comes up with a method of making the bottom water be related to initial rainfall and deciding the bottom water of the first-floor tank based on e[ementary losing of once rainfall directing at the method of making the bottom water of water-tank model parameterization. Then we use the hydrologic datum of Qingjiang Catchment to test the method and the result meets relevant standards.
