This paper focuses on the simulation of single rainfall-runoff events in the Ali-Efenti basin, a subbasin of the Pinios river catchment. This region suffers from frequent floods causing problems to the downstream agricultural and urban areas. Three winter storm-events were selected for the rainfall-runoff simulations. The simulation is performed using the NAM model, a basic component of the DHI MIKE 11 package. The NAM hydrological model is a deterministic, conceptual, lumped model that consists of a set of linked mathematical statements, describing in a simplified quantitative form the behavior of the land phase of the hydrological cycle. The NAM model is based on semi-empirical equations, which describe the physical structures and procedures and as a lumped, it treats each catchment as a single unit. Two of the events were used for the calibration phase, while one was used for the verification giving results with good accuracy. Keywords: NAM, rainfall-runoff, lumped, conceptual, flood forecasting, hydrological model, hydrological simulation. 1 Introduction A number of mathematical models have been proposed by different authors to face the problem of flood forecasting (Baltas, ). In most of these models, combinations of linear conceptual elements are used to simplify the representation of hydrological processes. Hydrologists have always been
