EXTENSION OF THE SOIL CONSERVATION SERVICE RAINFALL-RUNOFF METHODOLOGY FOR UNGAGED WATERSHEDS

The estimation of direct runoff for ungaged watersheds is a common problem in engineering hydrology. The method of the Soil Conservation Services (SCS) is widely used due to its ease of application. Runoff estimates are based upon the soil types and land use practices occurring within a watershed. This report presents an extension of the SCS method employing modern physically based infiltration equations. The table permits the estimation of direct runoff by physical infiltration equations for any ungaged watershed for which a curve number may be determined by knowledge of soil types and land use.
