Abstract

Ringlet Reservoir in Cameron Highlands impounds water mainly from four main rivers namely Sg. Telom, Sg. Habu, Sg. Ringlet and Sg. Bertam. Due to the absence of gauge flow data, MIKE NAM rainfall runoff model was used to simulate inflow for short term and long term prediction. Peak flow is sensitive towards any changes in U max , TG, CQOF, CKBF, CKIF and CK 1,2 . All parameters except CK 1,2 are sensitive in calculation of total volume. Model was calibrated for the period from 1999 to 2006 and validated for the period from 2010 to 2012 at two streamflow locations. The model is reliable to simulate flow satisfactorily especially during flood events. Model shows good agreement between the simulated and observed flow in terms of low flow, peak flow and total volume. Good calibration results were achieved for all scenarios, with NSE > 0.66, RSR < 0.6, R2 > 0.74 and PBIAS (%) < 15%.
