This study presents an application of rainfall-runoff model (NAM model) as a part of MIKE 11 model to simulate flood in Southern Thailand, namely Tapi basin and U-Thaphao basin. Tapi basin at Phra Saeng with catchment area of 5200 km2 has been divided into 2 sub catchments area and U-Thaphao basin at Hat Yai with catchment area of 1740 km2 has been also divided into 2 sub catchments. The study deals with different combination of rainfall station with three cases for each basin, in order to get a good resemblance between simulated and observed discharge. The model has been calibrated using concurrent daily streamflow, daily rainfall and monthly evaporation data. It has been also verified using independent data to assess its predictive reliability. The applicability of the model to simulate flood is provided in the shape and size of hydrograph. however, the peak flows are still not coincident with the observed periods in time to peak and duration.
