Water resource management is essential for the integration of different users and water availability for the whole society in a sustainable way. Thus, it is important to generate data to support the planning and the watershed management in an ecologically balanced way. Considering the above, the objective of this research is to estimate the water flow in seven points of the Rio Verdinho watershed, in the Goiás’ southwest region, Brazilian Cerrado. The Soil and Water Assessment Tool (SWAT) model was used for this study, the modeling was performed in ArcSWAT and the calibration was made in SWAT-Calibration and Uncertainty Procedures (SWAT-CUP), using the Sequential Uncertainty Fitting algorithm for sensitivity analysis. The results after the calibration process (NS = 0.53, R² = 0.83 and PBIAS = -22.5) show that the SWAT model satisfactorily simulated the flow, being observed that the SWAT-CUP had difficulty adjusting the terrestrial variables evapotranspiration and base flow. This study will serve as a support for others researchers in Cerrado environments, mainly in the Goiás’ southwest region, where studies with the referred model are not observed. The results will also subsidize the effectiveness and efficiency of the public actions and policies in the local and regional water management.
