    • AnnAGNPS ephemeral gully erosion simulation technology 

      Bingner, R.L.; Theurer, F.D.; Gordon, L.M.; Bennett, S.J.; Parker, C.; Thorne, C.; Alonso, C.V. (Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      Tillage-induced ephemeral gully erosion has been shown to be a significant and sometimes dominant source of sediment within a watershed. An approach has been developed within AnnAGNPS to assess the impact of conservation ...
    • Ephemeral gullies: to till or not to till? 

      Gordon, L.M.; Bennett, S.J.; Alonso, C.V.; Bingner, R.L. (Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      While the perceived magnitude of ephemeral gully erosion may be masked after gullies are repaired, the action of plowing in these channels reduces topsoil thickness and crop productivity over a much wider area than the ...
    • Ephemeral gully erosion research: processes and modeling 

      Alonso, C.V. (Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      The USDA Natural Resources Conservation Service (NRCS) defines ephemeral gullies as small channels that can be filled in by normal tillage operations only to reform in the same location by subsequent runoff events. Ephemeral ...
    • Relation between the location of check dams and adjacent vegetation cover in ephemeral gullies (Southeast Spain) 

      Conesa García, C.; Pérez Cutillas, P.; García Lorenzo, R. (Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      In general, the work carried out on vegetation in the Mediterranean catchments is focused more on the hillside vegetation cover than the riparian. Apart from occasional contributions by Alcaraz et al. (1997), Salinas et ...
    • Some examples of ephemeral gully erosion in an Atlantic area of NW Spain 

      Valcárcel, M.; Paz, A.; Vidal, E. (Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      This study aimed to describe types of ephemeral gullies and to determine their origin, evolution and importance as sediment sources in Galicia (Northwest Spain). Concentrated erosion was surveyed on medium textured soils, ...
    • Waterfall erosion as a main factor in ephemeral gully initiation in a part of Northeastern Iran 

      Sadeghi, S.H.R.; Rangavar, A.S.; Bashari, M.; Abbasi, A.A. (Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      The present study assesses the factors controlling gully formation in a study area located in northeastern Iran. Gully erosion in northeastern Iran is very high because of the high rate of human encroachment and the resulting ...
