Resumo: Inadequate releases of sanitary sewage and solid waste in water resources promote the gradual contamination of the water. This study aimed at the integration of qualitative and quantitative information in a watershed highly urbanized and intense human activity detrimental to water quality. The basin is located in the urban area of the municipality of Santa Maria-RS, with 2.7 km² area. The probability curves were constructed for total BOD and coliforms, E. coli, DO, nitrite and nitrate. The retention curves were used to obtain the TMDLs curves relating to water quality parameters. The results obtained show that the Cancela Tamandaí creek receives daily high loadings of organic matter,TC, EC, nitrite, nitrate and the concentration of DO in 90% of the time is less than 1.0 mg / L. The curves of probability of daily loads together with the TMDL curves are alternatives to the planning of remediation actions in the creek, or are tools thatmay assist in the management of water resources and water quality management in the Cancela-Tamandaí watershed. The TMDL curves have a simple methodology and results can be easily applied, enabling the practical use in water management.

Este estudo teve como objetivo a integração das informações quali-quantitativas em uma bacia hidrográfica altamente urbanizada e com intensa atividade antrópica prejudicial à qualidade da água. A bacia situa-se na área urbana do município de Santa Maria-RS, com área de 2,7  km². As curvas de probabilidade foram construídas para DBO e Coliformes totais, E. coli e OD, nitrito e nitrato. As curvas de permanência foram utilizadas para a obtenção das curvas de CMTDs referente aos parâmetros de qualidade de água. Os resultados obtidos mostram que o Arroio Cancela-Tamandaí recebe diariamente elevadas cargas de matéria orgânica, CT, EC, nitrito, nitrato e que a concentração de OD em 90% do tempo é inferior a 1,0 mg/L. As curvas de probabilidades das cargas diárias em conjunto com as curvas de CMTD são alternativas para o planejamento de ações de despoluição no arroio, ou seja, são ferramentas que podem vir a auxiliar no gerenciamento dos recursos hídricos e na gestão da qualidade da água na bacia hidrográfica Cancela-Tamandaí. As curvas de CMTD apresentam uma metodologia simples e os resultados podem ser facilmente aplicados, possibilitando o uso prático na gestão das águas.Universidade Federal de Uberlândia2018-12-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/36414Sociedade & Natureza; Vol. 30 No. 3 (2018); 1-17Sociedade & Natureza; v. 30 n. 3 (2018); 1-171982-45130103-1570reponame:Sociedade & natureza (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUporhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/36414/pdfCopyright (c) 2018 Revista Sociedade & Naturezainfo:eu-repo/semantics/openAccessdos Santos, Sizabeli AmaralPivetta, Glaucia GhestiFilho, Osmar SchmidtGastaldini, Maria do Carmo Cauduro2020-07-03T10:46:46Zoai:ojs.www.seer.ufu.br:article/36414Revistahttp://www.sociedadenatureza.ig.ufu.br/PUBhttps://seer.ufu.br/index.php/sociedadenatureza/oai||sociedade.natureza.ufu@gmail.com|| lucianamelo@ufu.br1982-45130103-1570opendoar:2020-07-03T10:46:46Sociedade & natureza (Online) - Universidade Federal de Uberlândia (UFU)false
