    • Agricultural land use, piping and gullies activity in the Huelva lower valley (Saragossa, Spain) 

      Echeverría, M.T.; Ibarra, P.; Pérez Cabello, F. (Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      The variations in the total amount of surface used for arable crops both for dry farming and fallow land, with regard to the different “agricultural policies”, have modified the natural dynamics of some processes such as ...
    • Gullies on mars: the debate about formative processes (keynote) 

      Howard, A.D. (Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      The discovery of very young gully systems on Mars has occasioned a lively debate about the processes and materials involved in their formation (Malin and Edgett, 2000). The strong interest in these features results because ...
    • The importance of the presence of gullies in the production of sediments in semiarid areas (Murcia, south-east of Spain) 

      Romero Díaz, A.; Martínez Lloris, M.; Alonso Sarría, F.; Belmonte Serrato, F. (Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      The study has shown how the existence of gullies remarkably increases the rates of erosion and, therefore, the volume of sediments that arrives at the dikes of hydrological correction. A consequence of this is the need to ...
    • Surfaces of gullies generated by piping process in abandoned fields (south-east of Spain) 

      Romero Díaz, A.; Marín Sanleandro, P.; Sánchez Soriano, A. (Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      The piping process have an important development in old agricultural terraced fields. The abandonment of these fields, together with the lithologies, hydraulic and climatic characteristics favour the quick development of ...
