Preliminary geometric model of the Barreiras Aquifer derived from hydrogeophysics data at the River Catu basin, NE Brazil

Hydrogeophysical Characterization of Fractured Aquifers for Groundwater Exploration in the Federal District of Brazil

“…The results presented above generally agree with previous studies, which were carried out in different regions of Brazil, focusing on various groundwater regimes that highlight the role of litho-stratigraphy and hydrogeological features on the aquifer systems, which includes their geometries as well as hydrogeological characteristics [11][12][13][14][15][16][17]. The effects of porosity, permeability, and faults (acting as a barrier slowing water flow or connectors between aquifers) on the transmissivity are evaluated [35].…”

“…The ERT technique has been widely used to investigate many sites around the world for various purposes, including bedrock detection, geological mapping, and groundwater exploration [6][7][8][9][10]. Recent case studies of hard rock aquifers in Brazil have highlighted the significance of regional structures, hydrogeology, and petrophysical properties of the site in groundwater development [2,[11][12][13][14]. Geological structures determine the aquifer geometry and the hydrogeological properties [15,16].…”

Reserve evaluation of a fault-conditioned aquifer: the Barreiras Aquifer in the coastal region of NE Brazil

“…Recent studies highlight the significant influence of regional structure on the hydrogeological and petrophysical properties of aquifer systems in Brazil (Lucena et al 2006, Soares et al 2007, Balsamo et al 2010, Rodrigues et al 2011, Lucena et al 2013. According to Burazer et al (2010) and Diaz et al (2014), lithostratigraphy and geological structure are important factors that affect aquifer geometry and determine hydrogeological characteristics.…”

Considerações Sobre a Conexão Hidráulica Profunda De Um Aquífero Não Confinado Em Zonas De Falha a Partir De Dados Isotópicos, Ne/Brasil

“…Outros autores também relatam o papel da topografia e falhas associadas na recarga de aquíferos estruturalmente isolados, usando modelos numéricos 3D (GREEN et al 2010, BALL et al 2014. No entanto, em termos de Nesta conjuntura, algumas pesquisas desenvolvidas no Nordeste do Brasil evidenciaram que a estrutura regional tem forte influência no contexto hidrogeológico e petrofísico, principalmente naqueles terrenos sedimentares de idade Cenozóica (LUCENA 2005, BALSAMO et al 2010, RODRIGUES et al 2011, LUCENA et al 2013. Esses estudos mostraram, dentre outros aspectos, a delimitação de áreas com alta transmissividade devido ao aumento da espessura saturada causada pela compartimentação estrutural local do Aquífero Barreiras e da Formação homônima (de idade Terciária-Quaternária).…”
