Flood volume and peak discharge from small catchments in southern Africa based on the SCS technique

Abstract

There is a need in southern Africa for hydrological information which will assist engineers/hydrologists responsible for the planning of hydraulic structures, in making economic and safe design decisions. Estimates of design flood characteristics (e.g. peak discharge, runoff volume and hydrograph shape) from small catchments (<8 km ) in southern Africa are generally derived by the use of mathematical runoff models, since only limited gauged hydrological data are available. A major problem associated in the use of such flood estimation models is the scarcity of adequate input information to the models and the lack of familiarity with the various techniques. In 1979 a report, "Estimation of Volume and Rate of Runoff from Small Catchments in South Africa, Based on the SCS-Technique" was published by Schulze and Arnold of the Department of Agricultural Engineering of the University of Natal, Pietermaritzburg, to address the above needs.
