Abstract
In this study, rainfall-runoff model have been used to determine the rainfall-runoff relationship for un-gauged catchment area in Pahang. This research is aim to develop a rainfall-runoff model using HEC-HMS for un-gauged catchment area and to predict the streamflow in un-gauged catchment for Sungai Betau, Sungai Jelai Kecil, and Sungai Serau. HEC-HMS 3.5 is used for this study to stimulate the discharge for the un-gauged catchment area. This study use three rainfall data and one streamflow data, starting from year 1999 to 2014. The parameters used for this study included time of concentration, storage coefficient, and lag time. Few methods are being used to perform this analysis, that is transform method (Clark Unit Hydrograph), baseflow method (Constant Monthly), and loss method (SCS Curve Number). Hydrological model will be stimulated to predict flood discharge after calibration and verification models. To evaluate the performance of hydrological model, root mean square error (RMSE) will be used. The calibrated model can be used for flood discharge prediction. By comparing the RMSE, it can be conclude that RF 4514032 are more suitable to be used to predict the discharge for un-gauged catchment area at Sungai Betau, Sungai Jelai Kecil, and Sungai Serau.
