Gully dynamics: initiation and morphology
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
The paper reviews general conditions for initiation and
maintenance of gullies.
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 ...
Historical gully erosion with loess areas of SE Poland – Natural conditions and human impact
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
Gullies constitute one of the most characteristic elements
of loess relief in SE Poland. Particularly dense net of
permanent gullies – in some places more than 10 km?km-2 –
appears in areas of specific conditions of ...
Soil erosion on the bottom of hollows in steppe zone of Ukraine
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
Soil erosion, undoubtedly, is one of the main ecological
and agricultural problems in the world. Quantity of eroded
lands in Ukraine achieves 10.5 millions ha. Annual losses of
soil constitutes about 600 millions tons ...
When did gully erosion start to be accelerated in the Penedès – Anoia vineyard region (NE Spain)?
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
Gully erosion in the Penedès-Anoia (NE Spain) region is not a past phenomenon. In
this respect, recent research by Martínez-Casasnovas et al.
(2003) has shown that neat erosion rates in gullies reach
576±58 Tn ha-1 year-1 ...
Does vegetation cover suppose gully erosion stabilization?
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
The present research is
addressed to study the evolution of vegetation cover on
gully sidewalls and its influence on sediment production
due to gully erosion and on gully walls’ stabilization. A
sample gully system of the ...
Sidewall erosion control strategies in gullies of the Penedès – Anoia vineyard region (NE Spain)
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
The objective of this work
is to formulate different sidewall erosion control strategies
to reduce retreat and sediment production rates in the
gullies of the Penedès-Anoia (NE Spain) region.
Influence of snowmelt and heavy rainfalls on water and sediment yield from loess gully catchment (Lublin upland – Poland)
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
The surface discharge from the gully catchments of the
Lublin Upland (Poland) usually is not very high and
amounts to about 15 mm·yr-1. It is mainly an episodic
discharge of snow/rainfall regime. Surface runoff and ...
Effectiveness of palm and bamboo geotextiles in reducing concentrated flow erosion
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
Rills and gullies, caused by concentrated flow erosion,
represent an important sediment source in many environments
(Poesen et al., 2003). Studies indicate that vegetation can be
very effective in controlling gully ...
Estimating sediment yield from gully erosion using easily measurable morphometric characteristics in Darehshahr region, south of I.R. Iran
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
A case study was conducted in a part of Ilam Province,
I.R. Iran, to establish a reliable model for estimating
sediment yield from gully erosion. The attempt was
satisfactory and led to an applicable model whose input
could ...
