Resumo: | Water is an irreplaceable natural resource for the maintenance of life on Earth. For human consumption, the depreciation of its quality can have different consequences on public supply. Therefore, the objective was to relate turbidity with precipitation of 50 hydrographic basins whose sources are used for public supply in the State of Espírito Santo. Fifty points of adduction of raw water used in the treatment and supply to the public supply network were selected, using their monthly averages of turbidity of 48 months, from 2006 to 2008. The hydrographic basins were delimited using a hydrologically consistent digital elevation model, obtained in a GIS environment. Precipitation data were spatialized using the ordinary kriging geostatistical technique. A regression analysis was performed between turbidity and precipitation resulting in equations with R² between 0.01 and 0.89 for the entire period; R² between 0.01 and 0.96 for the dry season (April to September); and 0.04 and 0.88 for the rainy season (October to March). The relationship between Tr and Pm is a good indicator for predicting turbidity levels, but the use of longer analysis periods for greater accuracy of the adjustments is recommended. |

Para o consumo humano, a depreciação de sua qualidade pode ter consequências diversas no abastecimento público. Sendo assim, objetivou-se relacionar a turbidez com a precipitação de 50 bacias hidrográficas cujos mananciais são utilizados para abastecimento público no Estado do Espírito Santo. Foram selecionados 50 pontos de adução de água bruta empregada no tratamento e fornecimento à rede de abastecimento público, utilizando-se suas médias mensais de turbidez de 48 meses, de 2006 a 2008. As bacias hidrográficas foram delimitadas com a utilização de um modelo digital de elevação hidrologicamente consistido, obtido em ambiente SIG. Os dados de precipitação foram espacializados utilizando a técnica geoestatística krigagem ordinária. Foi realizada a análise de regressão entre a turbidez e a precipitação resultando em equações com R² entre 0,01 e 0,89 para o período todo; R² entre 0,01 e 0,96 para o período seco (abril a setembro); e 0,04 e 0,88 para o período chuvoso (outubro a março). A relação entre Tr e Pm é um bom indicativo para predição de níveis de turbidez, porém recomenda-se utilizar períodos de análise mais longos para maior precisão dos ajustes.EDUFU - Editora da Universidade Federal de Uberlândia2023-02-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado pelos paresapplication/pdfhttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/6190110.14393/RCG249161901Caminhos de Geografia; Vol. 24 No. 91 (2023): Fevereiro; 132-152Caminhos de Geografia; Vol. 24 Núm. 91 (2023): Fevereiro; 132-152Caminhos de Geografia; v. 24 n. 91 (2023): Fevereiro; 132-1521678-6343reponame:Caminhos de Geografiainstname:Universidade Federal de Uberlândia (UFU)instacron:UFUporhttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/61901/35614Copyright (c) 2023 Pedro Henrique Silva Penedo, Giovanni de Oliveira Garcia, Roberto Avelino Cecílio, Sidney Sara Zanetti, Mariza Pereira de Oliveira Rozahttp://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessPenedo, Pedro Henrique SilvaGarcia, Giovanni de OliveiraCecílio, Roberto AvelinoZanetti, Sidney SaraRoza, Mariza Pereira de Oliveira2023-02-22T20:06:07Zoai:ojs.www.seer.ufu.br:article/61901Revistahttps://seer.ufu.br/index.php/caminhosdegeografia/indexPUBhttp://www.seer.ufu.br/index.php/caminhosdegeografia/oaiflaviasantosgeo@gmail.com1678-63431678-6343opendoar:2023-02-22T20:06:07Caminhos de Geografia - Universidade Federal de Uberlândia (UFU)false |
