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
Based on the on-the-spot artificial simulated rainfall test and the measurement of double-ring infiltration and the observation of runoff cell under natural rainfall, the law and characteristics of water infiltration on various types of underlying surface in Hegou River Basin are systematically studied. The infiltration model of the pros and cons 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
