Résumé Karst aquifers are valuable groundwater resources whose management requires the use of functioning hydrogeological models. The KARSYS approach provides an explicit 3D conceptual model of the geometry and the functioning of karst aquifers that has been successfully applied in Swiss and Slovenian aquifers. In this work, KARSYS is applied in a complex geological area: the Picos de Europa National Park (Spain). The hydrogeological 3D model (500 km2) shows an alpine karst aquifer compartmentalized into 32 groundwater bodies dammed up by subvertical barriers creating elevated saturated zones (water tables at 1153 m asl) and lower ones (water tables at 145 m asl). The recharge is through 18 spring catchment areas. The groundwater flows to the saturated zones pass through vertical to inclined trajectories, and phreatic flows are oriented toward NW, NE and N. KARSYS can be applied to any geologically complex area at a regional scale, although the geological structure should be simplified and the precision in some places is low.

Titre Influence of the rivers on speleogenesis combining KARSYS approach and cave levels. Picos de Europa, Spain Type Book Chapter
Année 2015 Publication Hydrogeological and environmental investigations in karst systems. Environmental Earth Sciences Revue Abrégée (down)
Volume 1 Numéro Pages 599-607
Mots-Clés Karsys
Résumé The influence of rivers on speleogenesis is studied analyzing the cave

levels located in the underground drainage areas related to two fluvial basins. Cave

levels are analyzed through their vertical distribution profiles. The underground

limits of the fluvial basins are defined using a 3D geometric model of the karst

aquifer established according to the KARSYS approach. The aim of this work is to

analyze the influence of the rivers on cave evolution using cave morphology. The

study area corresponds to the Western and Central massifs of Picos de Europa

(Northern Spain), with 214 km of cave conduits up to 1.6 km vertical range. As a

result, we established two sequences of development of the cave levels related to

the differences of the incision rate of the Cares and Dobra Rivers, and the partial

capture of the Western Massif by the Cares River.
