本文采用现场实地人工模拟降雨试验 ,并结合双环入渗测定以及天然降雨条件下的径流小区观测等手段 ,对河沟流域各类型下垫面水分入渗规律及特征进行了较为深入系统地研究 ,并对各入渗模型的优劣进行了分析、比较及评价。结果表明 :考斯加可夫 (Kostiakov)公式以及霍顿 (Horton)公式较符合河沟流域的实际入渗情况
In this paper, on-site artificial simulated rainfall test, combined with double-ring infiltration determination and runoff observation under natural rainfall and other means, all types of underlying surface water infiltration law and characteristics of the Hegou River Basin conducted a more in-depth and systematic study and The advantages and disadvantages of each infiltration model were analyzed, compared and evaluated. The results show that the Kostiakov formula and the Horton formula are more in line with the actual infiltration of Hegou watershed
