Adaptation of the SCS [Soil Conservation Service] runoff equation for a (Sub) humid monsoon climate by Yilak, Debebe L., Tilahun, Seifu A., Schmitter, Petra S., Nakawuka, Prossie, Haile, Alemseged Tamiru, Kassawmar, N. T., Guzmán, Christian D., Steenhuis, Tammo S.

“…When estimating runoff contributing area within a watershed and assessing the runoff mechanisms, we have used the original concept of SCS-CN approach in a 113 ha Anjeni and 113ha Maybar Watersheds in the headwaters of the Blue Nile Basin, North Ethiopian highland. Analysis was done at daily, weekly and biweekly base using nine years of hydrological data (1988-97) by classifying the rainfall seasons in to six based on the seasonal cumulative of effective rainfall (Pe). …”
