_Rainfall runoffestimationfrom a watershed is ofvital importance as these values
are required in most hydrologic analysis for the purpose ofwater resources
planning. This study deals with Layang River rainfall runoff estimation using
MIKE 11 NAM model. The calibration and validation procedures were carried
out to provide a satisfactory estimation. The runoff discharges were simulated for
a 12-year period (1988-2000). The simulated peak flow occurred in. 1992
and 1995 with approximate values of 20.94 mJls and 18.93 m% respectively.
The optimum values -of the model parameters obtained during the calibration procedure
were presented. The reliability ofMIKEl1 NAM was evaluated based
on the Efficiency Index (EI) and Root Mean Square Error (RMSE). The EI and
RMSE obtained during this study are 0.75 and 0.08 respectively.
