黄土高原严重水土流失是与暴雨引起的地表径流一同发生的。暴雨径流的研究对治黄工作有重大的实践意义。现行暴雨径流量的研究大多是按测站资料,采用建立暴雨径流相关关系的方法。在利用实验资料进行理论推导方面还研究得不多。暴雨径流关系的建立,在湿润地区主要是基于蓄满产流理论,关于这一理论在国内外已有不少的论述,但对半干旱与干旱地区的超渗产流理论则论证较少。我们在黄河水土保持的研究任务中,采用了人工模拟降雨的方法,通过实验途径初步探讨了暴雨径流的超渗产流理论,并在这一理论的基础上初步探索了计算与预报暴雨径流量的方法。实验研究系在陕西黄龙水土保持站的试验流域上进行,根据流域的自然条件,选择了各种典型地
Severe soil and water loss in the Loess Plateau occurred along with surface runoff caused by heavy rainfall. The study of storm runoff has great practical significance for governance of the Yellow River. The current storm runoff research mostly based on station data, the establishment of stormwater runoff correlation. There is not much research on the use of experimental data for theoretical derivation. The establishment of storm-runoff relationship is mainly based on the theory of runoff accumulation in humid regions. There have been many expositions on this theory at home and abroad, but there is less evidence for the theory of excess runoff in semi-arid and arid regions. In the research task of soil and water conservation of the Yellow River, we adopted the method of artificial rainfall simulation, and discussed the theory of hyper-seepage flow of stormwater runoff experimentally. Based on this theory, we first explored the calculation and prediction of stormwater runoff Methods. The experimental research was carried out on the pilot basin of Huanglong Soil and Water Conservation Station in Shaanxi Province. According to the natural conditions of the basin, various typical
