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 ...
Effects of slope processes and management in gullying
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
Most erosion studies have been typically done in rill and
interrill areas because the complexity of gullies and their
large size have made their study very difficult.
Morgan (1979) and Hudson (1985) define gullies as
water ...
Evaluating airborne laser scanning for gully erosion detection and baseline mapping in the Fitzroy catchment, QLD, Australia
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
Australia’s climate and land management practises have
resulted in an increased threat to land condition and water
quality through sediment transported by gully erosion. The
Fitzroy River catchment is located in Queensland ...
Hydrological effects of the sediments deposited off a hillslope affected by rill erosion: project outlines and preliminary results
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
The main objectives of this project are (i) to evaluate
the sedimentation rate generated by rill erosion in a
hillslope and the granulometric characteristics of the
sediment deposited off this hillslope, and (ii) to ...
Proposed methodology to quantify ephemeral gully erosion
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
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 ...
Implications of recent experimental findings for rill erosion modeling
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
The major aim of this paper is to critically review
the theoretical concepts that are underpinning current
models of rill flow and sediment detachment in the light of
recent experimental results and, when necessary, to ...
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 ...
Modelling the occurrence of gullies in semi-arid areas of south-west Spain
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
Modern predictive models represent a powerful tool for
predicting and analyzing geomorphological phenomena like
gullying. The model obtained presents a high percentage of
success in classifying gullied and ungullied ...
Ephemeral gully headcut development and migration in stratified soils
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
The objectives of the current study were: (1) to quantify
the effect of an erosion resistant (ER) soil layer placed at
various depths within a soil profile on headcut development
and migration; and (2) to assess the ...
Gullies on mars: the debate about formative processes (keynote)
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
The discovery of very young gully systems on Mars has occasioned a lively debate about the processes and materials involved in their formation (Malin and Edgett, 2000). The strong interest in these features results because ...
