Effect of topography on retreat rate of different gully headcuts in Bardenas Reales area (Navarre, Spain)
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
In Northeast Spain, gullying is a widespread phenomenon.
This type of erosion is especially intense in Bardenas Reales
(Navarre) where at least two major typical kinds of gully
headcut are present. A first group developed ...
AnnAGNPS ephemeral gully erosion simulation technology
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
Tillage-induced ephemeral gully erosion has been shown to
be a significant and sometimes dominant source of sediment
within a watershed. An approach has been developed within
AnnAGNPS to assess the impact of conservation ...
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.
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 ...
Alluvial gully erosion: a landscape denudation process in Northern Australia
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
Recent aerial reconnaissance surveys and subsequent
remote sensing mapping of Australia’s tropical rivers
identified alluvial gully erosion as a key sediment source
(Brooks et al. 2007; Knight et al. 2007). Gully erosion ...
Impact of root architecture, soil and flow characteristics on the erosion-reducing potential of roots during concentrated flow
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
In this study, the effects of roots of different root
morphologies (tap roots vs. fine-branched roots) on
concentrated flow erosion rates are studied experimentally.
The impact of soil type, soil moisture conditions ...
Scouring-sedimentation balance for gully reaches affected by check dams in Mediterranean environments
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
Many of the geomorphological impacts caused by check
dams are usually fairly common in torrential channels (bed
agradation upstream into the sedimentary wedges,
deepening and narrowing of the bankfull channel
downstream, ...
Gully erosion in central Italy: denudation rate estimation and morphoevolution of Calanchi and Biancane badlands
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
Long lasting geomorphological researches (Ciccaci et al., 1981, 1986, 2003; Del Monte et al., 2006) allowed the evaluation of denudation rates in some of the major catchments of Central Italy. It was observed a noticeable ...
Turbulent flow within headcut scour holes in rills and gullies
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
The objectives of the present study were to experimentally determine the time-mean turbulent flow characteristics within fixed-bed models of headcut scour holes typical of upland concentrated flows to assess soil erosion ...
Urban gullies in São Luis City, Maranhão State, Brazil
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
Urban gully erosion is a serious problem in São Luís
City, Maranhão State, Brazil. São Luís Municipality covers
831.7 km? and is situated in west-central Maranhão Island
(2º19’09”-2º51’00” S; 44º01’16”-44º19’37” W). ...
