A proposal to study gully erosion on silica sand and arkose slopes in central Spain
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
A research project to be developed, granted by the
Spanish Minister of Education and Science (project
CGL2006-07207), aims to investigate gully erosion on
silica sand and arkose slopes in Central Spain. The period of
the ...
Long term evolution of incised coastal channels on the isle of Wight, UK: insights from numerical modelling
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
Moderate rates of effective precipitation induce a
realistic incised channel network, providing there is a step
cliff profile present. Such a step profile is shown to be
produced by sea-level rise and associated cliff ...
Gully development in agricultural fields: insights from catchment scale analysis
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
The aim of this paper is to study the combined effect of human-induced
activity and the physical environmental conditions
on gully development in a small agricultural catchment in
Northern Israel. More specifically the ...
Concentrated flow erodibility of loess-derived topsoils: the impact of rainfall-induced consolidation and sealing
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
This study
investigates the impact of rainfall-induced soil consolidation
and soil surface sealing processes over time after tillage on
soil erosion during concentrated flow. The soil erodibility
(Kc) and critical flow ...
A comparison of anthropogenic and long-term soil erosion on banks peninsula using 137Cs and kawakawa tephra
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
The task of this study is to assess the severity of
anthropogenically induced soil erosion on a loess-mantled
hillslope on the foothills of Banks Peninsula, South Island,
New Zealand. The analysis is restricted to a slope ...
Improving the structural stability of cropped soils in Olite (Navarre) using conservation tillage to reduce water erosion
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
The objective of this work was to compare the soil wet aggregate stability and its relationship to the soil organic matter stock in an agricultural soil under different types of tillage in a semi-arid area of Northern Spain.
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 ...
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 ...
