Análise integrada de dados de sensoriamento remoto, geologia e geofísica no estudo de aqüífero fraturado, Lindóia - SP

Abstract: ABSTRACT. Detecting groundwater in fractured aquifers is always a difficult task. This paper presents the detailed study of a fractured aquifer in Lindóia region, São Paulo, Brazil. The study area was selected after a regional study analyzing the favorability for occurrence of groundwater which classified the area as being of excellent groundwater favorability. The study consisted on fractures mapping based on aerial photographs (scale 1:25,000) and geoelectrical survey (vertical electrical sounding and resist… Show more

“…The methodology of this work involved the integration of remote sensing, structural and electrical resistivity data (Madrucci et al, 2005;Fernandes, 2008;Francese et al 2009). Cartographic data were georreferenced in ArcGIS 10.4 (ESRI, 2015) using the horizontal Datum WGS-84 and the UTM map projection (Zone 24S).…”

“…Electrical profiling is indicated to detect lateral variations of subsurface resistivity at one or multiple depths approximately constant, through the shift of the set of electrodes with fixed spacing, which can identify faults and fractures, mapping geological contacts, structures and bodies which have a lateral heterogeneity of electrical resistivity (Madrucci et al, 2005;Keary et al, 2009). In this study the multilevel electric profiling was adopted, which registers the lateral variation of resistivity in multiple depth levels.…”

“…Por fim, a técnica geofísica de caminhamento elétrico tem sido utilizada para complementar a investigação estrutural de campo (MADRUCCI et al, 2005;RAYNER et al, 2007;WAHN-FRIED, 2010;RATNAKUMARI et al, 2012). O caminhamento elétrico possibilita a localização de descontinuidades do substrato rochoso em escala de sítio, permitindo relacioná-las com a topografia do terreno e com estruturas observadas em afloramentos.…”
