Synthetic unit hydrograph method is a popular method that plays an important role in a lot of planning in the field of water resources, especially in the analysis of immeasurrable watershed flood discharge. The simple method, as it only requires the data characteristics of the watershed. There are several methods such as synthetic unit hydrograph Nakayasu, Snyder-Alexeyev, SOS, ITB and GAMA-1 that have been developed abroad and in Indonesia. Pam river itself is located in District Gandus, Palembang, South Sumatra is included in the Boang sup-watershed. Pam river is the focus on research, because the river is one of the natural river in the city of Palembang to the watershed area of less than 2 km2. Tried some synthetic unit hydrograph formulas that can be used in the watershed Pam be the goal of this study and look for multiplier factor so that the synthetic unit hydrograph can be used in watershed Pam. Based on the performed analysis using unit hydrograph synthetic Gama I and unit hydrograph synthetic ITB-2, obtained peak discharge of 0.09143 m3 / s and a peak time of 2,842 hours for the unit hydrograph synthetic Gama I, for unit hydrograph synthetic ITB-2 obtained a peak debit of0.12344 m3 /s and a peak time of 1.005 hours. Multiplier factor sought the help of the application on excel solver and get a multiplier factor for unit hydrograph Gama I to date 10-04-16 peak time is at 0.430 and peak discharge at 1.520, date 17-04-16 peak time is at 0.474 and peak discharge at 1.660, 19-04-16 date time peak at 0.660 and peak discharge at 0.960. As for the coefficient multiplier for ITB HSS-2 of the HS Pam River date 10-04-16 peak time is at 0.312, peak discharge 4.000 and Cp (coefficient standart) by 0.400, the date of 17-04-16 peak time is at 0.350, the peak discharge at 4,000 and Cp (standart coefficient) at 0.600, dated 19-04-16 peak time is at 0.486, peak discharge at 3.000, Cp (strandart coefficient) at 0.700. The coefficients used for a multiplying factor to approach curve shape with a synthetic unit hydrograph unit hydrograph Pam River.
