    • Accuracy of methods for field assessment of rill and ephemeral gully erosion 

      Casalí Sarasíbar, Javier Upna; Loizu Maeztu, Javier Upna; Campo Bescós, Miguel Ángel Upna; Santisteban Comino, Luisa María de; Álvarez Mozos, Jesús Upna (Elsevier, 2006)   Artículo / Artikulua  OpenAccess
      To properly assess soil erosion in agricultural areas, it is necessary to determine precisely the volume of ephemeral gullies and rills in the field by using direct measurement procedures. However, little information is ...
    • Assessment of soil factors controlling ephemeral gully erosion on agricultural fields 

      Ollobarren Del Barrio, Paul; Campo-Bescós, Miguel Upna; Giménez Díaz, Rafael Upna; Casalí Sarasíbar, Javier Upna (Wiley, 2017)   Artículo / Artikulua  OpenAccess
      The soil factor is crucial in controlling and properly modeling the initiation and development of ephemeral gullies (EGs). Usually, EG initiation has been related to various soil properties (i.e. sealing, critical shear ...
    • Gully geometry: what are we measuring? 

      Casalí Sarasíbar, Javier Upna; Giménez Díaz, Rafael Upna; Campo-Bescós, Miguel Ángel Upna (European Geosciences UnionCopernicus Publications, 2015)   Artículo / Artikulua  OpenAccess
      Much of the research on (ephemeral) gully erosion comprises the determination of the geometry of these eroded channels, especially their width and depth. This is not a simple task due to uncertainty generated by the wide ...
    • Proposed methodology to quantify ephemeral gully erosion 

      Huang, C.; Nouwakpo, K.; Frankenberger, J.R. (Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      The overall objective of the proposed research is to identify and quantify landscape attributes and hydrologic conditions that can be used to assess hillslope seepage and ephemeral gully erosion. We propose to use three ...
    • The role of preferential flow through soil-pipes in ephemeral gully erosion 

      Wilson, G.V. (Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      The objective of this study was to quantify the hydrologic conditions under which discontinuous soil-pipes reestablish ephemeral gullies and continuous soil-pipes initiate ephemeral gullies.
