Kalibrasi Satu Dan Dua Parameter Pada Debit Banjir Di Sub-Das Rokan Menggunakan Program Hec-Hms
Floods occurred in Rokan Hulu are due to heavy rainfall with fairly long duration
and high rainfall. The main difficulty encountered in the analysis of river flooding
in Rokan Hulu is due to limited availability of data. An alternative to overcome
these limitations is to use a hydrological model. In this research was used as a
calibration adjustment process model parameter values to obtain a result of the
same model or close observation. This study aims to look at the characteristics of
the calibration using rainfall data and flow data hourly to the Transform Method
Clark Unit hydrograph and Transform Method Snyder Unit Hydrograph, by using
hydrologic Engineering Center Modeling System (HEC-HMS). The best result of
the calibration is to use two parameters, the results of two-parameter calibration
method Transform Method Clark unit hydrograph has the result Different Percent
Percent Peak = 0.0 m3/s and Different Volume = -7.6 mm and methods Transform
Method Snyder unit hydrograph have results Different Percent Peak = 0.0 m3/s
and Different Percent Volume = -23.43 mm. From the results of the calibration is
the best method is Transform Method Clark Unit Hydrograph.
