Resumo: The Cauê Aquifer is an important water supplier to the third largest urban agglomeration in Brazil. The Metropolitan Region of Belo Horizonte is in the Iron Quadrangle, site of intense iron ore mining, requiring large volumes of water and mine dewatering. In this context, we evaluate the regional impact on groundwater level between 2000 and 2019 based on a conceptual hydrogeological flow model on the eastern limb of the Moeda Syncline. This study includes the definition of boundary conditions and aquifer units, the calculation of hydrodynamic parameters, water balance, renewable reserve, and flow analysis. The Cauê, Gandarela, and Moeda aquifers are considered aquifer units, among which the Cauê Aquifer showed the highest hydraulic conductivity (9.45×10-7 m/s on average) as well as the highest recharge rate, with 38.67% rainfall. The average volume pumped was estimated at 41 million m³/year, equivalent to about 150% of the renewable reserve of the Cauê Aquifer, calculated at 27 million m³/year. Underground flow in the area tends southward, and the Cauê Aquifer acts as a water divide, which is less evident in the center of the area, where the greatest impact on groundwater level lowering occurs.

A Região Metropolitana de Belo Horizonte está inserida no Quadrilátero Ferrífero, local de intensa mineração de minério de ferro, necessitando de grandes volumes de água e desaguamento de minas. Neste contexto, avaliou-se o impacto regional no nível das águas subterrâneas entre 2000 e 2019 com base num modelo conceitual de fluxo hidro-geológico no braço leste do Sinclinal da Moeda. Este estudo inclui a definição de condições de contorno e unidades aquíferas, cálculo de parâmetros hidrodinâmicos, balanço hídrico, reserva renovável e análise de vazão. Os aquíferos Cauê, Gandarela e Moeda são considerados unidades aquíferas, dentre os quais o Aquífero Cauê apresentou a maior condutividade hidráulica (9,45×10-7 m/s em média) e a maior taxa de recarga, com 38,67% de precipitação. O volume médio bombeado foi estimado em 41 milhões de m³/ano, equivalente a cerca de 150% da reserva renovável do Aquífero Cauê, calculada em 27 milhões de m³/ano. O fluxo subterrâneo na área tende para o sul, e o Aquífero Cauê atua como um divisor de águas, o que é menos evidente no centro da área, onde ocorre o maior impacto no rebaixamento do nível do lençol freático.engUniversidade Federal de Minas GeraisUFMGBrasilIGC - DEPARTAMENTO DE GEOLOGIABrazilian Journal of GeologyÁgua subterrâneaHidrogeologiaImpacto ambientalRecursos energéticosGroundwaterHydrogeologyConceptual modelHydrogeological impactRenewable reserveThe cauê aquifer on the eastern limb of the moeda syncline: characterization, impacts, and flow in the western iron quadrangle (quadrilátero ferrífero), MG, BrazilO Aquífero Cauê no braço leste do Sinclinal da Moeda: caracterização, impactos e vazão no Quadrilátero Ferrífero ocidental (Quadrilátero Ferrífero), MG, Brasilinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://www.scielo.br/j/bjgeo/a/Tnm4vscJMtNs3BkYXVHhK5t/Celina Cenni de Castro MagalhãesNilson GuiguerMarília Carvalho de MeloRodrigo Sergio de Paulaapplication/pdfinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain;
