Reflexões sobre os critérios de cálculo de vazões outorgáveis em áreas de conflito do estado de Minas Gerais: o caso da Bacia do Ribeirão Ribeiro Bonito

The paper makes a comparison between different flow regionalization techniques considered in the management ofwater resources in Minas Gerais State and between them and the results of field hydrometric measurements. For illustration of thestudies is used the Ribeiro Bonito watershed as case study, unique location in the Rio das Velhas River Basin that has a ConflictArea Declaration (CAD) by low availability of water quantity in relation to the existing demands. The research highlights thatdifferent flow regionalization techniques produce different results if applied to areas with data limitations and in special inheadwater streams areas.
