O estudo de tais parâmetros é essencial para o conhecimento dos aquíferos, tanto com relação à sua localização como também em termos de qualidade e quantidade das águas. O K foi obtido matematicamente por meio da equação de HVORSLEV (1951) e pela análise gráfica, também pelo método de Hvorslev, no programa AquiferTest, a partir de dados do slug testes em piezômetros. T e S foram obtidos por ajustes gráficos no mesmo programa pelos métodos de Neuman e Boulton, e com base em testes de bombeamento em poços tubulares profundos. Nas análises de condutividade hidráulica, o método gráfico se mostrou mais eficiente e os valores obtidos são coerentes com os resultados de MOURÃO (2007) - indicando uma uniformidade desta característica do aquífero Cauê, em toda porção oeste do QF. Já os valores de T e S obtidos refletem a heterogeneidade e anisotropia do sistema aquífero, possivelmente relacionadas às regiões de confinamento e uma permeabilidade secundária, provavelmente associada ao controle estrutural do fluxo.This paper is based on the characterization of the hydrodynamic parameters hydraulic conductivity (K), transmissivity (T) and storage (S) in soft itabiritos of the southwest portion of the Quadrilatero Ferrifero (QF), MG. The study of these parameters is essential to the knowledge about aquifers, in terms of localization, quantity and quality of the water. The K was calculated using Hvorslev’s method and obtained by slug tests data for piezometers in the AquiferTest software. On the other hand, T and S had their results achieved using Neuman and Bouton methods also through the AquiferTest. The results were acquired by slope adjusts in graphs and the basis for these adjustments were pumping tests in deep tube wells. Considering the hydraulic conductivity, the graphic analyses were more effective and the results show a uniformity of this feature over the west QF, being consistent with MOURÃO (2007) studies. T and S, in turn, display the heterogeneity and anisotropy of the Caue iron formation probably caused by confined areas and secondary porosity due to the local structural complexity.porUniversidade Federal de Minas GeraisUFMGBrasilIGC - DEPARTAMENTO DE GEOLOGIAGeonomosAquíferosHidrogeologiaCongonhas (MG)Parâmetros hidrodinâmicosSlug testTeste de bombeamentoItabirito brandoEstudo dos parâmetros hidrodinâmicos obtidos em ensaios de campo em itabiritos brandos da porção sudeste do quadrilátero ferrífero, mgStudy of the hydridynamic parameters of soft itabiritos in the south-west portion of quadrilatero ferrifero obtained by fieldwork simulationsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttp://www.igc.ufmg.br/portaldeperiodicos/index.php/geonomos/article/view/1077/837Daniele Costa de MesquitaJúlia Cotta Maciel DantasRodrigo Sérgio de PaulaKênia Janete Guerraapplication/pdfinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain; charset=utf-82042https://repositorio.ufmg.br/bitstream/1843/51990/1/License.txtfa505098d172de0bc8864fc1287ffe22MD51ORIGINALESTUDO DOS PARÂMETROS HIDRODINÂMICOS OBTIDOS EM ENSAIOS.pdfESTUDO DOS PARÂMETROS HIDRODINÂMICOS OBTIDOS EM ENSAIOS.pdfapplication/pdf711734https://repositorio.ufmg.br/bitstream/1843/51990/2/ESTUDO%20DOS%20PAR%c3%82METROS%20HIDRODIN%c3%82MICOS%20OBTIDOS%20EM%20ENSAIOS.pdf6a29d3ab51af1ad72915cf386eca742aMD521843/519902023-04-14 17:18:45.446oai:repositorio.ufmg.br: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Repositório InstitucionalPUBhttps://repositorio.ufmg.br/oaiopendoar:2023-04-14T20:18:45Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false
