The methodology employed combines geological data obtained from wells with geo-electric profiles, thus allowing a more precise representation of an underground valley hitherto unknown, primarily related to the materials of the Middle Las Sierras Group (TQps-M), identified as the main aquifer in the area. The delineation of hydrogeological units was carried out considering geological and geophysical conditions, providing valuable information to understand the distribution and behavior of groundwater in the region. The precise identification and delineation of hydrogeological units enable better management of groundwater resources in the region. This more detailed knowledge enables more effective strategies for the preservation and sustainability of local aquifers.]]></p></abstract>
