Summary: Due to Brazilian hydrological monitoring network deficiency, several hydrographic basins do not present enough data for correct and efficient National Water Resources Policy instruments implementation. Thus, methods for estimating reference flows for streams sections lacking reliable records are necessary. The present study aims to compare permanence curves and minimum flows probability curves regionalization methodologies. The considered methodologies were Characteristic Values Method and Exponential Curve Method for permanence curves regionalization and Characteristic Values Method and Parameters Method for minimum flows probability regionalization in the portions of Itapemirim and Itabapoana basins located in the southern part of Espírito Santo State and covering small portions of the territories of the states of Minas Gerais and Rio de Janeiro. In addition, regional flow indicators were used to compare the reference flow values obtained through the analyzed regionalization methods. The method that presented best results, for both permanence curve and minimum flows probability curves regionalization, was the Characteristic Values. The regional flows indicators method showed to be a simple and consistent alternative for estimating reference flows in the study area.
