摘要
水箱模型也称Tank模型,是应用较为广泛的流域水文模型.模型将复杂的降水径流过程简单概化为流域的蓄水与出流关系进行模拟.针对皂河小流域的降水、径流和水循环等水文特性,建立了4层串联水箱模型,模拟流域的降水径流过程,计算流域径流量,并结合河流水质模型,综合模拟河流流量及主要水质指标变化.结果表明:各项指标的模拟值与实测值吻合较好,说明水箱模型用于小流域的径流模拟较为准确,可与水质模型耦合使用,综合模拟小流域的水文水质变化.
As an extensively used hydrological model, model tank can simplify the complicated process of rainfall and runoff into the relation between water amassment,infiltration and outflow to simulate runoff in a basin. In this paper, a four-layer tank model has been set up based on the hydrological characteristics of rainfall,runoff,and water recycle of a small drainage basin in Xi＇an ,and the runoff of Zaohe basin has also been simulated. Furthermore, the paper also combined water quality model with the coupling to simulate the change of runoff and quality and compared the simulation with test values. The results show that tank model can better simulate the runoff,and integrate simulation it is suitable for hydrology and quality change in a small basin.
