水文学实际上就是要解决降雨之后发生了什么的一门学科。自然条件下,由于流域所处的气候条件和下垫面条件并非单一,因此不同地方存在不同的产流特征。包气带结构的复杂性和降雨特性的多变性,很少见到一种包气带只有一种产流机制的情况。目前揭露出来的基本产流机制是超渗地面径流产流机制、地下水径流产流机制、壤中水径流产流机制和饱和地面径流产流机制等四种。文章针对超渗地面径流产流量的计算进行了归纳和总结。
Hydrography is actually a discipline to deal with what happened after the rains. Under natural conditions, because of the climatic conditions and underlying conditions of the basin are not unique, different runoff characteristics exist in different places. The complexity of the entrained belt structure and the variability of the rainfall characteristics rarely show the case that there is only one flow-producing mechanism in the entrained belt. The basic mechanism of the current run-off is that there are four kinds of mechanisms: the infiltration mechanism of groundwater runoff, the mechanism of runoff and runoff of groundwater, the runoff and runoff mechanism of soil runoff and the runoff and runoff of saturated ground. This paper summarizes the calculation of runoff yield of ultra-seepage ground.
