The implantation of the National Water Information System (SNIRH) created by the Law nº 9.433/97 requires, for its structure, the use of computational tools that allow the databases creation, necessary for planning and management of water resources. To the knowledge of water availability and hydraulic structures design is necessary to quantity the flow rate at any position of the stream, which is obtained from the use of regionalization methods. The present work aimed at developing a computational system for regionalization study of the minimum, maximum and average flow, the regularization curves and the permanence curve. The flow regionalization methods considered were: traditional, dimensionless curve and mass conservation. The database obtained from the National Water Agency (ANA) and encoded on Otto Pfafstetter System was integrated to the software to acquire automatically the watershed characteristics. Also, it was used web services to the importation of descriptive data and station fluviometric data, climate characteristics associated with watershed and the historical flow rate data series from the “Hidroweb” system. The developed software was called “Computer System for the Flow Rate Regionalization" (SisCoRV) and was applied to Paracatu river basin to check their functionalities. In the case study, the SisCoRV had a good interaction with the Internet, ease delineation of homogeneous regions, efficiency in applying the regionalization methodology and ability to feed the ANA database.
