Punpun

The report deals with determination of SCS runoff Curve Number and land use changes for Hamidnagar sub-basin of Punpun basin. The design of any hydraulic structure calls for the estimation of runoff. The Soil Conservation Services model, developed by USDA, computes direct runoff through an empirical equation that requires the rainfall and watershed coefficient as inputs. The watershed coefficient is called the Curve Number (CN), which represents the runoff potential of the land cover-soil complex.
