This constraint makes HSS models will provide considerable benefits. Ideally each watershed has a Hydrograph Unit with certain characteristics. This study aims to observe the hydrograph characteristics of observations in each watershed and all watersheds in South Sulawesi Province. The main objective of this study is to design a Synthetic Unit Hydrograph Model, including the peak flood discharge equation (Qp) and the time to reach the flood peak (Tp), which among others is a function of the watershed area (A), longest river length (L), and form factor Watershed. The watershed form factor is the ratio of perimeter (K) and area (A) of the watershed. Model analysis uses regression with various alternatives. The result is synthetic unit hydrograph modeling (HSS) with a broad variable watershed (A), longest river length (L), and DAS (FD) form factor and of course according to the criteria of the coefficient of determination, it is expected to have a high enough sensitivity.
