Currently there has been an increase in water scarcity in the world, and the demand for this resource tends to increase in the coming decades. Thus, hydrological modeling becomes an indispensable tool in the evaluation and management of this natural resource. The objective of this study was to analyze the performance of the SWAT model for generating the flow rate of the Jari River watershed, in Amazon biome. The calibration, validation and analysis of modeling uncertainties were performed using the SUFI-2 algorithm. The results obtained show a good model performance verified by statistical metrics for the calibration and validation steps, respectively. The results permit to conclude that after the calibration, the model was able to adequately reproduce the flow, allowing its use as a management tool for the Jari River basin.
