The members of the Geomorphology Group of the Department of Earth Sciences who are involved in the present group focus much of their research on the analysis of geological hazards (sinkholes, landslides, piping, soil erosion, active faults and active salt structures).

Particularly noteworthy is the work on sinkholes, the group being the most frequently cited internationally.

Other lines of investigation include the production of geomorphological maps and geomorphological studies on Mars, as well as studies of soil degradation and erosion. These investigations are carried out in a wide range of regions, including countries such as the USA, Italy, Israel, Saudi Arabia and Iran.

Members of the group have written books with a broad international reach and are active in international scientific bodies (vice-presidency of the International Association of Geomorphologists), national bodies (vice-presidency of the Spanish Society of Geomorphology), and on the editorial committees of relevant journals (Geomorphology, Environmental Earth Sciences)- They provide consultancy services to both national and international institutions and companies (International Court of Justice, Iranian Ministry of Industry, Spanish Nuclear Security Council, ENRESA).

Members of the group belonging to the Department of Geography focus their research on the reconstruction of the climate of both the pre-instrumental and instrumental periods, including the recovery of climate data, the development of databases, the analysis of temperature trends and Its members are authors of the monthly precipitation and temperature (maximum and minimum) databases for the Spanish mainland, period 1916-2020, called MOPREDAS_century and MOTEDAS_century, respectively (Monthy precipitation Database of Spain and Monthly Temperature Database of Spain)”

Lines of investigation

  1. General and applied geomorphological mapping
  2. Geological hazards (sinkholes, landslides, active tectonic and gravitational faults, soil erosion, piping)
  3. Problems in dams associated with the presence of soluble formations (filtrations, salinization, instability)
  4. Deformation processes associated with saline structures
  5. Geomorphology and palaeohydrology on Mars
  6. Palaeoenvironmental studies based on geomorphological records

  • Participation of the IUCA in activities of the Green Week Unizar

    (Zaragoza, Wednesday, June 8, 2022). The Huesca and Teruel campuses and the San Francisco campus in Zaragoza joined the “Green Week” last Friday, June 3, as a prelude to the European Night of Researchers, which will be held on the last Friday of September. And they did it with workshops, scientific-healthy breakfasts, gymkhanas, sustainable mobility […]
