Abstract
Ogan River watershed is one of the watersheds in South Sumatra Province which has a total catchment area of 923.565 km2 with a length of ± 6,042 km. The Ogan River watershed is divided into several sub-watersheds based on the topographic conditions. This study specifically examines the condition of the Ogan River flood discharge in the Peninjauan Village, Subdistrict of Peninjauan, which has a catchment Area of 3168.95 km2 with a river length of ± 158.1 km. At some points of the Ogan River in the Peninjauan Village, siltation occurred so that during the rainy season the river overflows and causes flooding every year. Regency due to the changes of land use. This study used the rain data from the nearest rain post, Ogan River watershed map, land use map and the software to get spatial data. The analysis of planned flood discharge used Synthetic Unit Hydrograph (SUH) Gamma 1 with various land use changes. The results indicate that land use change from forest to settlement increases peak discharge.
