      Deconstructing the drivers of large-scale vegetation change is critical to predicting and managing projected climate and land use changes that will affect regional vegetation cover in degraded or threated ecosystems. We ...
    • Comparison between capacitive and microstructured optical fiber soil moisture sensors 

      López Aldaba, Aitor Upna; López Torres, Diego Upna Orcid; Campo-Bescós, Miguel Upna Orcid; López Rodríguez, José Javier Upna Orcid; Yerro Lizarazu, David; Elosúa Aguado, César Upna Orcid; Arregui San Martín, Francisco Javier Upna Orcid; Auguste, Jean-Louis; Jamier, Raphael; Roy, Philippe; López-Amo Sáinz, Manuel Upna Orcid (MDPI, 2018)   Artículo / Artikulua  OpenAccess
      Soil moisture content has always been an important parameter to control because it is a deterministic factor for site-specific irrigation, seeding, transplanting, and compaction detection. In this work, a discrete sensor ...
    • Demonstrating correspondence between decision-support models and dynamics of real-world environmental systems 

      Huffaker, Ray; Muñoz Carpena, Rafael Upna Orcid; Campo-Bescós, Miguel Upna Orcid; Southworth, Jane (Elsevier, 2016)   Artículo / Artikulua  OpenAccess
      There are increasing calls to audit decision-support models used for environmental policy to ensure that they correspond with the reality facing policy makers. Modelers can establish correspondence by providing empirical ...
    • Evaluation of 2D models for the prediction of surface depression storage using realistic reference values 

      Giménez Díaz, Rafael Upna Orcid; Mezkiritz Barberena, Irantzu; Campo-Bescós, Miguel Upna Orcid; Álvarez-Mozos, Jesús Upna Orcid; González de Audícana Amenábar, María Upna Orcid; Martínez de Aguirre Escobar, Alejandro Upna Orcid; Casalí Sarasíbar, Javier Upna Orcid (Wiley, 2016)   Artículo / Artikulua  OpenAccess
      Depression storage (DS) is the maximum storage of precipitation and runoff in the soil surface at a given slope. The DS is determined by soil roughness that in agricultural soils is largely affected by tillage. The direct ...
    • Evaluation of a gully headcut retreat model using multitemporal aerial photographs and digital elevation models 

      Campo-Bescós, Miguel Upna Orcid; Flores Cervantes, J. H.; Bras, R. L.; Casalí Sarasíbar, Javier Upna Orcid; Giráldez Cervera, Juan Vicente (American Geophysical UnionWiley, 2013)   Artículo / Artikulua  OpenAccess
      A large fraction of soil erosion in temperate climate systems proceeds from gully headcut growth processes. Nevertheless, headcut retreat is not well understood. Few erosion models include gully headcut growth processes, ...
    • Factors controlling sediment export in a small agricultural watershed in Navarre (Spain) 

      Giménez Díaz, Rafael Upna Orcid; Casalí Sarasíbar, Javier Upna Orcid; Grande Esteban, Ildefonso Upna; Díez Beregaña, Javier Upna; Campo-Bescós, Miguel Upna Orcid; Álvarez-Mozos, Jesús Upna Orcid; Goñi Garatea, Mikel Upna Orcid (Elsevier, 2012)   Artículo / Artikulua  OpenAccess
      It is recognised that the hydrological and erosion processes in watersheds are very much conditioned by the (inter)action of a number of variables. This paper covers a 15-year period of studying those factors that have ...
