Analisis Kalibrasi Model Hidrograf Satuan Sintetik Clark Dan Snyder Dengan Menggunakan Program Hec-Hms Studi Kasus : Sub Das Rokan Hulu Di Lubuk Bendahara

---

Application of Clark and Snyder Synthetic Unit Hydrographs In Lubuk Bendahara wathershed requires more detailed analysis. Rainfall data and automatic water lever recorder (AWLR) data in the field are needed as calibration and verification. Parameters of loss model, baseflow and transform method in Clark and Snyder Synthetic Unit Hydrographs are calibrated using HEC-HMS program. This calibration process uses three objective function methods, namely Peak Weighted Root Mean Square (RMS) Error, Percent Error Peak dan Percent Error Volume. Calibration results show that the Clark Synthetic Unit Hydrographs model is better when compared to the Snyder Synthetic Unit Hydrographs Model with the resulting value Peak-Weighted RMS Error 2,57, volume of difference -0,09% and peak flow of difference 1,1%. Calibration result parameters are then verified using rainfall data in the following year data during calibration. The results of verification show that calculated discharge are very large when compared to the observed discharge 671,26 m3/s.Keywords : Clark Synthetic unit hidrographs , Snyder Synthetic unit hidrographs HEC-HMS, Calibration, Verification
