Abstract
This study aims to establish the model of Dimensionless Synthetic Unit Hydrograph atGendong Watershed, Pasuruan Regency-East Java Province of Indonesia. The observed data of AutomaticWater Level Recorder at Gembong Warungdowo was used in this research and the Automatic RainfallRecorder at P3GI (Sugar Factory Central Research of Indonesia) from 2008 until 2011. The model wasdifferentiated by using the Collins Method. The result showed that the suitable model at Gembong watershedis as follow: the rising limb curve is Qn = Qp + 0.615 (t-Tp) and the recession line curve is Qt = Qp x e0.30 (TP-t).This result was based on the regression statistical analysis with the highest correlation of R2=0.993 and thestandard error minimum of SEY=1.143 for the rising limb curve, however, for the recession line curve isR=0.906 and SEY=0.415. The model is as follow: the rising limb is Qn = Qp + 0.615 (t-Tp) and the recessionline is Qt = Qp x e 0.30 (TP-t) .
