Abstract

This paper intended to investigate the characteristic of observed hydrograph in each watershed and all of watersheds in South Sulawesi Province. However, the main aim of this study is to formulate parameter model of Synthetic Unit Hydrograph such as Peak Discharge (Qp) and Time to Peak (Tp) as the function of watershed shape (FD). Formulation of peak discharge and time to peak in this study are based on the two physical characteristics watershed such as watershed round (K) and area number of watershed (A). Analysis of modeling uses regression method with some alternatives. Result indicates that factor of watershed shape (FD) has strong linear relation to the parameter of synthetic unit hydrograph
