Relation between the location of check dams and adjacent vegetation cover in ephemeral gullies (Southeast Spain)
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
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 ...
Ephemeral gullies: to till or not to till?
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
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
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
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 ...
AnnAGNPS ephemeral gully erosion simulation technology
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
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 ...
Some examples of ephemeral gully erosion in an Atlantic area of NW Spain
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
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
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
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 ...
