Assessment of two loss methods for estimation of surface runoff in Zaafrania urban catchment, North-East of Algeria

open access: yesJournal of Water and Land Development, 2018
Surface runoff is a major problem in urban catchments; its generation is always related to the amount of effective rainfall dropped over the surface, however in urban catchments the process is considerably altered by the emergence of impervious areas. In

径流曲线法(SCS-CN)的改进及其在黄土高原的应用

open access: yes, 2008
径流曲线法计算过程简单,所需的资料易于获取,尤其适用于资料缺乏的地区。本文针对黄土高原的降雨径流、土壤、气候特点,对径流曲线法进行了改进,并提出了一个简化、适应黄土区坡面和流域的降水产流模型,研究结果可为该区水资源高效利用、水土流失预报和治理提供重要帮助。主要结论如下:(1)运用黄土高原地区实测降水产流资料对标准SCS-CN模型进行了检验,发现标准CN方法对该区降水产流的预报效率偏低(E=0.294);经对参数初损率λ重新优化,模型预报精度虽有所提高,但预报效率仍只有0.541 ...
