Abstrak FADLUN. S. Dampala River Flood Discharge Analysis Based hydrographs of SYNTHETIC UNITS ITB-1 and ITB-2. (Guided by I Gede Tunas) Dampala River is a river located in Dampala Village. The river overflowed and caused people's homes to suffer damage due to flooding. The purpose of this study presents a simple approach to determining a consistent nondimensional unit hydrograph based on the principle of mass conservation. Unit hydrographs can be created using a single simple function (HSS ITB-1) or using two simple functions (HSS ITB-2) combined with an automatic adjustable peak discharge factor based on the ratio between watershed area to estimate peak flood discharge as the basis for disaster planning mitigation programs. This study was conducted to find out how much peak discharge is produced in the period of birthday 2 years to 100 years. The results of the ITB-1 Synthetic Unit Hydrograph based on a 2-year to 100-year re-period showed peak flood discharges ranged from 572.00 m3/second to 1029.59 m3/s, while the ITB-2 Synthetic Unit Hydrograph analysis based on the 2-year to 100-year anniversary period showed the peak discharge of the flood ranged from 711.12 m3/s to 1281.17 m3/s.
