该模型将“坦克”模型和“萨克拉门托”模型相结合并适当简化和改变而组成的,简称组合模型。整个模型分三层,分别模拟表层水(地表水和潜水),浅层地下水和深层地下水。第一层设置了两个并联水箱,第一个水箱主要起分水源作用,第二个水箱主要对第一个水箱分出的表层流按水量平衡原理作调蓄演算,对表层流起滞时作用。第二层、第三层由于出流过程平缓,故各设置一个水箱与第一层分水水箱垂直串联。由于流域陆面蒸发量年际变化很大,故本模型分别在第一层第一个水箱的下部和第二层水箱的上部设置了张力水,采用
The model is composed of “Tank” model and “Sacramento” model combined with appropriate simplification and change, composed of short, combined model. The whole model is divided into three layers, which simulate surface water (surface water and submersion), shallow groundwater and deep groundwater respectively. The first layer set up two parallel tanks, the first water tank mainly from the role of sub-water, the second tank mainly on the first tank out of the surface flow according to the principle of water balance for storage calculation, the surface flow from the lag effect. The second floor, the third floor due to outflow process is gentle, so set up a water tank and the first layer of vertical water tandem. Due to the large interannual variation of land surface evaporation in the basin, this model sets up tension water in the lower part of the first tank and the upper part of the second tank in the first floor respectively.
