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 ...
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 ...
Recent developments in gully erosion research and their implications for controlling soil loss and sediment yield
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
Soil erosion by water causes significant soil degradation
worldwide. Most erosion process research and erosion
control has focussed on sheet and rill erosion. Relatively
little research has dealt with (ephemeral) gully ...
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 ...
Assessment of gully erosion using photogrammetric techniques. A case study of upper Mbuluzi river, Swaziland
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
Swaziland is severely affected by gully erosion contributing
to a sediment budget up to 250,000 m3 y-1 (WMS Associates,
1988). This type is more important than inter-rill and rill
erosion. Severe gully erosion is mainly ...
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 ...
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 ...
Gully erosion in mountain area of SW-China, assessed using 137Cs and 210PBEX tracers and GPS survey
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
Gullies are extensively distributed in the Upper Yangtze
River Basin, SW-China. But the impact of these gullies on
total sediment output is still not clear because there is no
reliable technique for quantifying this ...
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 ...
Runoff and sediment supply from small gullied and ungullied basins in a semi-arid grazed environment
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
The aim of the present study is to determine links between rainfall, runoff, gully erosion and sediments. The extent of sediment yield (suspended sediment and bedload) and runoff response from gullied and ungullied basins ...
