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 ...
Hydrological and sediment dynamics within a small catchment with badland areas
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
Badlands are the main sediment source areas affecting
the headwaters of the Gállego and Aragón rivers in the
Central Spanish Pyrenees. These morphologies characterise
the landscape of the Inner Depression, occupying ...
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 ...
Erosion processes at the gully scale: observations, quantification and interpretation of field data from the Draix laboratory
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
In the Southern French Alps, the black marls formation
covers a large area and is highly susceptible to weathering
and erosion. It has a badlands topography and is subject to
high solid transport, bringing high sediment ...
Regional assessment of gully systems in a hilly olive-orchard dominated landscape
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
Olive orchards dominate the land use at the hills of Afrin
area, and olive oil represents the most important cash
income source for rural communities in this area. However,
olive yields in many orchards have been decreasing ...
Gully erosion in semi-arid landscapes - monitoring of processes and development
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
The research project MoGul (Large-scale Monitoring of
Gully Erosion in Semi-Arid Landscapes) at Trier and
Frankfurt University investigates the various types,
development and dependencies of gullies as well as
geomorphological ...
Gully development and topographic threshold, case study: Kerman Province, southeast of I.R. Iran
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
This research indicated that gully erosion can severely
damage croplands in this area of Iran. Significant gully
development occurred in the 3 years of study and the
product of drainage headcut area and slope was more
strongly ...
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 ...
Comparison of historical evolution of gully networks on both Slovak and Moravian forelands of the white Carpathians
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
The main objective of the contribution is to present the
preliminary results of comparison of historical evolution of
gully networks in both Slovak and Moravian forelands of the
White Carpathians. This geomorphic unit ...
Gully erosion risk zoning: proposal of a methodology and case study
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
Gullying is the most advanced, complex stage of erosion
processes, with more local destructive power than other
types of erosion (São Paulo, 1990). In this paper, we
propose a method to generate gully erosion risk zoning ...
