Resumo: For the analysis of water availability in a hydrographic basin the knowledge of the reference flow rate becomes indispensable. In the state of Minas Gerais the flow rate Q7,10, is used, in which a portion of this reference flow rate is granted, which can be defined by different methodologies. In this sense, this study aims to analyze the surface water availability of the Suaçuí river basin (MG) using three methodologies to define the reference flow rate: statistical analysis of historical flow series in the fluviometric stations; Surface water runoff in the state of Minas Gerais; and Flow regionalization study to improve the allocation process in the state of Minas Gerais. Considerable variations between the methods used were verified, with intervals of -19.94% to 1304.6% comparing the two flow regionalization methods used, in relation to the analysis of the data from the fluviometric stations. By the different methods, the water levels captured in the respective sub-basins do not produce impacts capable of compromising water availability, except for the area upstream of the "Fazenda Corrente" station, where the results indicate a certain degree of compromising water availability. Future research that compares other methods of flow regionalization is recommended, seeking results with smaller statistical variations in relation to the observed fluviometric stations, or even the development of specific methods for the studied watershed, in order to contribute to the decision-making process in the management of water resources.

En el estado de Minas Gerais, se utiliza el caudal Q7,10, en el que se concede una parte de este caudal de referencia, que puede definirse por diferentes metodologías. En este sentido, este estudio tiene como objetivo analizar la disponibilidad de agua superficial de la cuenca del río Suaçuí (MG) utilizando tres metodologías para definir el caudal de referencia: análisis estadístico de las series de caudales históricos en las estaciones fluviométricas; escorrentía superficial en el estado de MG; y estudio de regionalización de caudales para la mejora del proceso de asignación en el estado MG. Las variaciones entre los métodos utilizados son considerables, con intervalos de -19,94% a 1.304,6%, comparando los dos métodos de regionalización del flujo utilizados, en relación con el análisis de los datos de las estaciones fluviométricas. Por los diferentes métodos, los caudales captados en las respectivas subcuencas no producen impactos capaces de comprometer la disponibilidad de agua, excepto en la zona aguas arriba de la estación "Fazenda Corrente", donde los resultados indican un cierto grado de compromiso de la disponibilidad de agua. Se recomienda la realización de futuras investigaciones que comparen otros métodos de regionalización de caudales, buscando resultados con menores variaciones estadísticas en relación a las estaciones fluviométricas, o incluso el desarrollo de métodos específicos para la cuenca hidrográfica estudiada, con el fin de contribuir al proceso de toma de decisiones en la gestión de agua.Para análise de disponibilidade hídrica de uma bacia hidrográfica o conhecimento da vazão de referência torna-se indispensável. No estado de Minas Gerais utiliza-se a vazão Q7,10­, em que é outorgada uma parcela dessa vazão referencial, esta que pode ser definida por diferentes metodologias. Nesse estudo, objetivou-se comparar diferentes metodologias de definição de vazão de referência para análise da disponibilidade hídrica superficial da bacia hidrográfica do rio Suaçuí (Minas Gerais), sendo elas: análise estatística de séries históricas de vazões nas estações fluviométricas; Deflúvios superficiais no estado de Minas Gerais; e Estudo de regionalização de vazão para o aprimoramento do processo de outorga no estado de Minas Gerais. Verificou-se consideráveis variações entre os métodos utilizados, com intervalos de -19,94% a 1.304,6% comparando os dois métodos de regionalização de vazões utilizados, em relação à análise dos dados existentes. Pelos diferentes métodos, verificou-se que as vazões captadas nas respectivas sub-bacias não produzem impactos capazes de comprometer a disponibilidade hídrica, exceto para a área à montante da estação Fazenda Corrente, em que os resultados indicam certo grau de comprometimento da disponibilidade hídrica. Recomenda-se pesquisas futuras que comparem outros métodos de regionalização de vazões, buscando resultados com menores variações estatísticas em relação às estações fluviométricas observadas, ou até mesmo o desenvolvimento de métodos específicos à bacia hidrográfica estudada, no sentido de contribuir para o processo de tomada de decisão no gerenciamento dos recursos hídricos.Research, Society and Development2022-02-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2598710.33448/rsd-v11i3.25987Research, Society and Development; Vol. 11 No. 3; e0211325987Research, Society and Development; Vol. 11 Núm. 3; e0211325987Research, Society and Development; v. 11 n. 3; e02113259872525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/25987/22931Copyright (c) 2022 Guilherme de Barros Moreira; James Lacerda Maia; João Paulo Oliveira Silvahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMoreira, Guilherme de Barros Maia, James Lacerda Silva, João Paulo Oliveira 2022-03-09T13:44:38Zoai:ojs.pkp.sfu.ca:article/25987Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:44:08.183066Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
