Water resources in Kucuk Menderes Watershed have been adversely affected by anthropogenic activities and climate change. Increasing population and uncontrolled water uses have transformed the watershed into a water-stressed watershed. Modeling studies in water resources are required to solve these problems in the watershed. In this study, a hydrological model for the watershed was established using SWAT (Soil and Water Assessment Tool). The model calibration and sensitivity analysis were performed by SWAT-CUP (SWAT-Calibration Uncertainty Programs) using Sequential Uncertainty Fitting (SUFI-2) method. The model was mostly sensitive to CN2, SOL_BD (layer#), RCHRG_DP and SOL_K (layer#) parameters. The performance of the model was evaluated with P-factor, R-factor and objective functions. P-factor values were in the range of 61-80%, meaning that the monitoring data were matched by the model within this range. According to the objective functions, the model performance was evaluated as satisfactory. The results of this study could serve as a base for a wide range of studies in the watershed such as effects of climate change, the effectiveness of Best Management Practices (BMPs) on water resources and water quality modeling.
