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; ...
Causes of gully erosion in arid ecosystem: case study southern part of I.R. Iran
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
This research demonstrated that the I.R. region is prone
to gully erosion. The study area had limited gully erosion
four decades ago. With accelerating urban development
during the past, two to three decades, areas of gully ...
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 ...
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 ...
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 ...
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 ...
Gully erosion on cinder cones of Tenerife (Canary Islands, Spain)
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
The aim of this study is to observe the evolution of gully
erosion on cinder cones over time and verify whether or not
age is a critical factor in the level of degradation of scoria
cones, independent of other factors.
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 ...
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 ...
