Progress in gully erosion research: IV International Symposium on Gully Erosion
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
Libro / Liburua,
The classic forms of water erosion of the soil comprise sheet, rill, and gully erosion. According to the concept most
generalized, in sheet erosion, thin layers of material are uniformly removed from the soil surface due ...
Morphology and controlling factors of landslide cirque gullies: a case study from the Sprogu gravas nature monument (SE Latvia)
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
Human-induced changes of landscape and the vegetation
cover have been recognized in the majority of studies focusing
on gully formation as one of the most important factors
triggering the development of gullies throughout ...
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 ...
Discharge and gully erosion in a small rangeland catchment
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
Valley bottom gullies are a common feature in rangelands.
Although these gullies are found in the bottom of drainage
lines, information about the relationship between discharge
and gullying is scarce (Crouch, 1990; ...
Surfaces of gullies generated by piping process in abandoned fields (south-east of Spain)
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
The piping process have an important development in old
agricultural terraced fields. The abandonment of these
fields, together with the lithologies, hydraulic and climatic
characteristics favour the quick development of ...
The importance of the presence of gullies in the production of sediments in semiarid areas (Murcia, south-east of Spain)
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
The study has shown how the existence of gullies
remarkably increases the rates of erosion and, therefore, the
volume of sediments that arrives at the dikes of hydrological
correction. A consequence of this is the need to ...
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 ...
Seepage flow in aquifers with open and closed boundaries
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
At previous gully erosion conferences, the effect of
surface seal development on gully formation and growth
was analyzed (Prasad and Römkens, 2003) and the effect of
hydrological conditions on gully growth was discussed
(Römkens ...
