Karst environments are characterized by the high solubility of specific bedrock lithologies, mainly carbonate or evaporites. Karst terrains show distinctive landforms and dominant subsurface drainage, which may lead to karst-related environmental and engineering problems such as subsidence (sinkholes), landslides, floods, or aquifer pollution. Karst-related hazards have been increasing because of expanding urban areas and global change in recent decades. Consequently,\u202fnatural and human-induced hazards related to karst are receiving increasing attention from the scientific community and administrations. The investigation of the epigenic and hypogenic karst requires multidisciplinary research, which must integrate geomorphological mapping, remote sensing, geotechnical monitoring, geophysics exploration, trenching and retrodeformational analysis.<\/p>\n<\/div>

Our objectives are<\/h3>\n
    \n
  1. \u00a0determine environmental factors (lithological, climatic, anthropogenic, etc…) that control karstic dissolution processes and subsidence hazards at different scales from sinkholes to saline extrusions-diapirs. Study areas include the evaporite karstic systems of Ebro and Fluvi\u00e0 valleys (NE Iberian Peninsula) and carbonate karst in Florida Peninsula (North America).<\/li>\n
  2. determine hydro-geomorphological and climatic factors controlling natural acid rock drainages in mountain areas. Study sites are in the Central-Eastern Pyrenees and the Puna region in the Andes Cordillera (South America).<\/li>\n<\/ol>\n<\/div>

    We work in an international research group led by F.Gut\u00ederrez (Universidad de Zaragoza<\/em>), with research interests in geohazards, geomorphology and environmental geology. This collaboration materialises in the joint participation in competitive projects and contracts (Iberdrola, Endesa). We also maintain stable collaboration with C.Roqu\u00e9 (Universitat de Girona-UdG<\/em>) and X.Comas (Florida Atlantic University<\/em>-FAU).<\/div>\n\t\t<\/div>
