Use of geotechnologies in the evaluation of hydrogeological favorability in fractured aquifer aquifers

Abstract

This article deals with the mapping of hydrogeological favorability in fractured aquifers, in the so called Circuito das Águas Paulista. Remote sensing and geospatial analysis techniques were used to create and combine geological, physiographic, structural, land cover, and favorability maps. These data were manipulated in geographic information systems, aiming the mapping of hydrogeological favorability, using Fuzzy logic. The favorability mapping was shown according to the specific capacity values and to the distribution pattern of the wells. In addition, the trend surface generated from the specific capacity data was in accordance with the favorability map, corroborating the accuracy of the applied method, showing a high hydrogeological favorability in the Águas de Lindóia and Lindóia municipalities.
