摘要
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)
Mainly based on the field simulated rainfall experiments ,the infiltration law in Hegou watershed was systematically studied.The result showed that Horton infiltration model f(t)=f c+(f o-f c)e -kt and kostiakov infiltration model f(t)=at -n were suitable for the watershed.
