Abstract
The construction of a weir on the Lematang river in Semidang Alas village in the town of Pagar Alam of South Sumatra Province is intended to provide the irrigation water for the Lematang irrigation area with a planned area of paddy fields of 3000 ha. This study was conducted to analyze and evaluate the design flood discharge in the weir construction planning because it will be one of the main parameters in the construction of a strong and stable weir construction to be passed by flood discharges, with the RR (Rainfall-Runoff) method using the application of HEC-HMS (Hydrology Engineering Center-Hydrology Modeling System) and Gamma Synthetic Hydrograph (HSS) 1. The results of the calculation of the design flood discharge by means of the HEC-HMS applications are far more satisfying than those by means of the Gamma HSS 1. It is indicated by the difference in the value of the design flood discharge by means of the Gamma 1 HSS method which is not is too significant between that of the return period of 100 years and that of the return period of 1000 years. Unlike the case with the calculations using HEC-HMS, because in this method there is a distribution of parameters divided into several sub-watersheds, so the conditions in the field are more illustrated. The results of the simulation show that the design flood discharge with HEC-HMS was 119.3 m3/s over a 100-year return period.
