    • On the assimilation set-up of ASCAT soil moisture data for improving streamflow catchment simulation 

      Loizu Maeztu, Javier Upna; Massari, Christian; Álvarez Mozos, Jesús Upna; Tarpanelli, Angelica; Brocca, Luca; Casalí Sarasíbar, Javier Upna (Elsevier, 2018)   Artículo / Artikulua
      Assimilation of remotely sensed surface soil moisture (SSM) data into hydrological catchment models has been identified as a means to improve stream flow simulations, but reported results vary markedly depending on the ...
    • Photogrammetrical and field measurement of gullies with contrasting morphology 

      Marzolff, I.; Giménez Díaz, Rafael Upna; Seeger, M.; Campo Bescós, Miguel Ángel Upna; Ries, J. B.; Casalí Sarasíbar, Javier Upna; Álvarez Mozos, Jesús Upna (Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      Despite a wealth of studies on monitoring different types of gullies by using remote-sensing technique such as photogrammetry, relatively few efforts have been made to test their accuracy. Therefore the question arises as ...
    • Progress in gully erosion research: IV International Symposium on Gully Erosion 

      Casalí Sarasíbar, Javier Upna; Giménez Díaz, Rafael Upna (Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)   Libro / Liburua  OpenAccess
      The classic forms of water erosion of the soil comprise sheet, rill, and gully erosion. According to the concept most generalized, in sheet erosion, thin layers of material are uniformly removed from the soil surface due ...
    • Runoff, nutrients, sediment and salt yields in an irrigated watershed in southern Navarre (Spain) 

      Merchán Elena, Daniel Upna; Casalí Sarasíbar, Javier Upna; Valle de Lersundi, Jokin del; Campo Bescós, Miguel Ángel Upna; Giménez Díaz, Rafael Upna; Preciado, Beatriz; Lafarga, Alberto (Elsevier, 2018)   Artículo / Artikulua
      The environmental impact of irrigated agriculture on water quality was assessed in Landazuria watershed (Navarre, northeast Spain), a 479.5 ha watershed with 53% of irrigated agricultural land. In the framework of a long-term ...
