Multi-technical approach to evaluate the impacts caused by the Vazante Mine (MG) on the Santa Catarina River flow loss through the overexploitation of a fissure-karst aquifer and simulation of mitigating solutions by numerical modeling
Year: 2023

The water loss in rivers and streams is one of the immediate effects of aquifer overexploitation. Particularly in the context of underground mining, notable changes in the natural groundwater flow regime are observed due to the pumping required to keep underground galleries drained. In the northwest region of the Brazilian state of Minas Gerais, in Vazante municipality, the Santa Catarina River (SCR) undergoes a drying up processes related to the Vazante underground mine dewatering. To properly
