Short-term effects of post-fire salvage logging on runoff and soil erosion
Malvar, Maruxa C.; Silva, Flávio C.; Prats, Sergio A.; Vieira, Diana C.S.; Coelho, Celeste O.A.; Keizer, J. JacobResearch has been undertaken on the hydrological and erosional impact of forest fires, but remarkably little work has been conducted on salvage logging operations that often follow them. We assessed the effects of mechanical salvage logging following wildfire on soil physical properties, ground cover, and runoff and erosion response on a eucalypt stand in Portugal. We compared two levels of mechanical disturban...
Surface and subsurface flow in eucalyptus plantations in north-central Portugal
Boulet, Anne-K.; Prats, Sérgio A.; Malvar, Maruxa C.; González-Pelayo, Oscar; Coelho, Celeste O. A.; Ferreira, Antonio J. D.; Keizer, Jan J.In the Baixo Vouga region of north-central Portugal, forests occupy half of the territory, of which two thirds are Eucalypts plantations. The hydrological implications of this large-scale introduction of eucalypt are unknown and the aim of this exploratory study, realized in the Caramulo Mountains, was to describe overland flow (OLF), subsurface flow (SSF) and stream flow (Q) in a catchment dominated by Eucalyp...
Assessing the role of pre-fire ground preparation operations and soil water rep...
Malvar, Maruxa C.; Martins, Martinho A. S.; Nunes, João P.; Robichaud, Peter R.; Keizer, J. JacobThis study addressed the impacts of contrasting pre-fire ground preparation operations on post-fire runoff and inter-rill erosion in six eucalypt plantations in north-central Portugal, with a special emphasis on the role of soil water repellency in the seasonal patterns of overland flow generation. To this end, a down slope ploughed, a contour ploughed and a terraced site were compared with three unploughed sit...
