Application of SCS model on computing the surface runoff of different land use types-A case study on Yuyao, Zhejiang Province(SCS模型在不同土地类型地表产流计算中的应用)

产流量计算是进行城市防洪及水土保持效益评估的关键.结合余姚地区土壤资料及典型性降雨事件的观测数据,对降雨量、降雨初损值、最大潜在入渗量、产流量四者的关系进行了深入分析,基于土地利用功能建立了适用于平原水网地区的SCS(Soil Conservation Service)扩展模型,并在余姚地区开展了降雨地表产流验证.实验结果表明,基于SCS扩展模型的径流量计算值和实测值之间的绝对误差在0. 14〜1. 36 mm,二者具有很好的一致性....
