Abstract

The Sierra de Hinodejo karst system has developed in favor of a calcareous group from the Upper Cretaceous. It is divided into narrow synclinal aquifers with a groundwater reserve capacity of between 1.85 and 2.41 hm3 It is a nonconfined aquifer of 41 km2 of extension where the natural recharge is mainly autogenous and diffuse. The groundwater flow is directed by the bottom of the synclines towards the Villabuena springs (121 l/s) and ephemeral springs of  the Izana River gorge in high waters. All springs have a highly variable flow. Subterranean transfers to the Calcareous Tertiary and Cretaceous of the Almazán Basin are important. The flat northern part has preserved to a great extent the hydrogeological functioning of the first phases of karstification. The erosion and exhumation of Cretaceous anticlinal domes to the south during the Quaternary have allowed grounwater transfer to ephemeral springs associated with important tufface-closure lagoon systems.
