Modeling of hydrochemistry evolution in carbonatic–siliciclastic aquifer system in coastal environment
(2021-08-01)
Coastal regions are quite populous, causing coastal aquifers to be overexploited, due to which contamination of these aquifers is observed. The municipality of Belém, located on the eastern edge of the Amazon Forest, is ...

High-resolution aquifer analog of fluvial-aeolian sediments of the Guarani aquifer system
(2013-08-07)
The Guarani aquifer system (GAS) represents one of the biggest aquifers in the world and is the most relevant groundwater resource in South America. For the first time, by combining field and laboratory measurements, a ...
Assessing hydrofacies and hydraulic properties of basaltic aquifers derived from geophysical logging
(Soc Brasileira Geologia, 2020-01-01)
Basaltic aquifers are an important source of water supply in many regions worldwide. Because of their cooling process, flood basalts normally have complex internal structures and unpredictable permeable zone distribution. ...
