The Soil Water Assessment Tool (SWAT) model was used to simulate streamflow in the Cidacos River in Navarra. SWAT could help in predicting future hydrological impacts due to agricultural land use changes such as transformation from rainfed to irrigated agriculture. The model’s suitability was assessed by carrying out parametrization, sensitivity and uncertainty analysis, calibration, validation, and assessing its performance using statistical indicators. Streamflow in the watershed was calibrated and validated between the years 2000-2010 and 2011-2020 respectively at the Olite gauging station. Uncertainties in the model were analyzed using the p-factor and r-factor which satisfactory results for both calibration and validation periods. Statistical performance indices provided a good match between the observed and simulated values which indicated that the SWAT model was very satisfactory for simulation of stream flow in the watershed.
