Concentrated flow erodibility of loess-derived topsoils: the impact of rainfall-induced consolidation and sealing
Knapen, A.; Poesen, J.; Baets, S. de (Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaThis study investigates the impact of rainfall-induced soil consolidation and soil surface sealing processes over time after tillage on soil erosion during concentrated flow. The soil erodibility (Kc) and critical flow ... -
Effectiveness of palm and bamboo geotextiles in reducing concentrated flow erosion
Smets, T.; Langhans, C.; Poesen, J.; Knapen, A. (Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaRills and gullies, caused by concentrated flow erosion, represent an important sediment source in many environments (Poesen et al., 2003). Studies indicate that vegetation can be very effective in controlling gully ... -
Gully erosion in mountain area of SW-China, assessed using 137Cs and 210PBEX tracers and GPS survey
Li, Y.; Poesen, J.; Liu, L. M.; Li, L.; He, F. H.; Zhang, Q. W.; Li, R. (Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaGullies 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 ... -
Impact of root architecture, soil and flow characteristics on the erosion-reducing potential of roots during concentrated flow
Baets, S. de; Poesen, J.; Knapen, A. (Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaIn 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 ... -
Recent developments in gully erosion research and their implications for controlling soil loss and sediment yield
Poesen, J. (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 ...
