Physically based watershed models are increasingly being used to support decisions about alternative management strategies in the areas of land use change, climate change, water allocation, and pollution control. Therefore, the ability of these hydrological models to reproduce the physical process of the watershed must be carefully evaluated, as well as the uncertainty in modeling predictions. We evaluate in this study the capability of the SWAT (Soil and Water Assessment Tools, Arnold et al., 2000) model in reproducing the hydrology of two small Mediterranean watersheds through sensitivity, calibration and uncertainty analysis. The objective is to compare different calibration techniques for assessing model performance and modeling uncertainty
