Photogrammetrical and field measurement of gullies with contrasting morphology
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaDespite a wealth of studies on monitoring different types of gullies by using remote-sensing technique such as photogrammetry, relatively few efforts have been made to test their accuracy. Therefore the question arises ... -

(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaIn this work the authors present two sites that will help understand the processes that drive gully formation in the uplands of northern Mississippi and how these processes are affected by anthropomorphic influences. The ... -
Progress in gully erosion research: IV International Symposium on Gully Erosion
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 ... -
A proposal to study gully erosion on silica sand and arkose slopes in central Spain

The period of the ... -
Proposed methodology to quantify ephemeral gully erosion
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaThe overall objective of the proposed research is to identify and quantify landscape attributes and hydrologic conditions that can be used to assess hillslope seepage and ephemeral gully erosion. We propose to use three ... -
QTL mapping of pathogenicity in Heterobasidion annosum sensu lato
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2006) Contribución a congreso / Biltzarrerako ekarpenaHeterobasidion annosum (Fr.) Bref. sensu lato, casual agent of annosum root rot in conifers, is the economical most devastating forest pathogen in the northern hemisphere. A genetic linkage map of H. annosum, was ... -
Ras module function is involved in regulation of sexual development Schizophyllum commune
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2006) Contribución a congreso / Biltzarrerako ekarpenaThe white rot fungus Schizophyllum commune is used as a model to investigate sexual development in hymenomycetes. We isolated the gene gap1 encoding a GTPase-activating protein for Ras. Disruption of gap1 should therefore ... -
Rat cytochrome P450-mediated transformation of dichlorodibenzo-Pdioxins by recombinant white-rot basidiomycete Coriolus hirsutus
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2006) Contribución a congreso / Biltzarrerako ekarpenaRat cytochrome P450, CYP1A1, has been reported to play an important role in the metabolism of mono-trichlorodibenzo-p-dioxins (M-TriCDDs). To breed lignin (and M-TetraCDDs)-degrading basidiomycete Coriolus hirsutus strains ... -
Recent developments in gully erosion research and their implications for controlling soil loss and sediment yield
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaSoil 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 ... -
Regional assessment of gully systems in a hilly olive-orchard dominated landscape
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaOlive 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 ... -
Relation between the location of check dams and adjacent vegetation cover in ephemeral gullies (Southeast Spain)
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaIn general, the work carried out on vegetation in the Mediterranean catchments is focused more on the hillside vegetation cover than the riparian. Apart from occasional contributions by Alcaraz et al. (1997), Salinas et ... -
The role of preferential flow through soil-pipes in ephemeral gully erosion
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaThe objective of this study was to quantify the hydrologic conditions under which discontinuous soil-pipes reestablish ephemeral gullies and continuous soil-pipes initiate ephemeral gullies. -
The roles of SC3 and SC15 of Schizophyllum commune during growth on wood
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2006) Contribución a congreso / Biltzarrerako ekarpenaThe SC3 hydrophobin plays several roles in growth and development of S. commune. It lowers the surface tension of the aqueous substrate, enabling aerial growth, and it coats the aerial hyphae rendering them hydrophobic. ... -
Runoff and sediment supply from small gullied and ungullied basins in a semi-arid grazed environment
