Resum
During 2013 a set of different studies were made at the carbonate aquifer of Gruta de las Maravillas (Aracena) in order to get a better understanding of its hydrogeological functioning and especially on its relation with the adjacent detrital aquifer located beneath the urban area of Aracena. The water table and some physicochemical parameters have been measured using a set of water points, the most part of them being traditional drilled wells of low depth. The recorded data allow us to infer an approximated functioning of the aquifer. The results of this work suggest two main flows, north-south direction, that surround Cerro del Castillo and converge at its southern flank. This outline seems to be related to the quaternary alluvial aquifer which largely lies below the urban area. Though it requires additional studies, we can infer that the high piezometric surface, found at the Cabildo zone, might be related to some leakages produced by a preexisting sewerage network. The proposed hypothesis suggests the existence of an underground flow which extends from the recharge zone through the carbonate materials of Cerro del Castillo. This flow might be diverted toward the west and southeast, due to the presence of less permeable metamorphic materials, continuing flowing through the alluvial materials.
