Favorability analysis has been applied as a method to evaluate the correlation between the structural lineament and flow behavior in aquifers. The analysis was carried out in the outcropping areas of Tubarão Group, between the cities of Campinas and Sorocaba (São Paulo State, Brazil). The study area was chosen because of its geological complexity and the consequent lower predictability of well performance before drilling. To apply this method, we considered as “mineralized” areas those regions with highest specific capacity values, taking also into account six types of variables interpreted from radar images Landsat 7-ETM, Shuttle Radar Topography Mission (SRTM) and structural geological maps. The results reveal that the region encompassing between the cities of Elias Fausto and Monte Mor presents the best correlation with structural lineation which can be a factor in the high potential for groundwater exploration in this area.
