Autor: Eufemia Varela, M. Rodríguez-Alleres, E. Benito

Publikováno v: Journal of Hydrology and Hydromechanics, Vol 67, Iss 2, Pp 129-134 (2019)

The primary purpose of this work was to assess the persistence of water repellency in the surface horizon of coarse-textured soils under natural Quercus robur ecosystems, and Pinus pinaster and Eucalyptus globulus plantations, in the northwest of the

Influence of wildfire severity on soil physical degradation in two pine forest stands of NW Spain

Autor: María Eufemia Varela, Jan Jacob Keizer, E. Benito

Publikováno v: CATENA. 133:342-348

This study examined the effect of wildfire on the physical degradation of two forest soils in NW Spain and compared this against changes produced by controlled laboratory heating experiments in which unburned soils from neighbouring sites were expose

Environmental Factors Governing Soil Water Repellency Dynamics in a Pinus Pinaster Plantation in NW Spain

Autor: Elena Benito Rueda, M. Rodríguez-Alleres, Eufemia Varela Teijeiro

Publikováno v: Land Degradation & Development. 27:719-728

Soil water repellency (SWR) is a dynamic property that changes throughout the year. The objective of this work was to identify the environmental factors governing the temporal patterns in SWR in a pine plantation in northwest Spain with a view of pre

Publikováno v: Cuadernos de Investigación Geográfica, Vol 41, Iss 1, Pp 149-164 (2015)

Wildfires increase plot-scale soil erosion rates across the world. However, very few studies have monitored post-fire erosion losses at the catchment scale, especially in the Mediterranean region. The FIRECNUTS project was originally set out to addre

Soil water repellency is a widespread property of Pinus pinaster forest soils in Galicia (NW Spain) that can be intensified by soil heating during fires. Fire-induced or -enhanced soil water repellency, in combination with reduced vegetation and litt

Impact of wildfires on surface water repellency in soils of northwest Spain

Autor: E. de Blas, E. Benito, María Eufemia Varela

Publikováno v: Hydrological Processes. 19:3649-3657

Soil water repellency (hydrophobicity) is a naturally occurring phenomenon that can be intensified by soil heating during fires. Fire-induced water repellency, together with the loss of plant cover, is reportedly the principal source of increased sur

Physical soil degradation induced by deforestation and slope modification in a temperate-humid environment

Autor: María Eufemia Varela, E. de Blas, E. Benito

Publikováno v: Land Degradation & Development. 12:477-484

Between February 1998 and March 1999 physical soil degradation was studied in temperate-humid NW Spain after deforestation and slope modification. Changes in bulk density, total porosity, pore size distribution, aggregate stability and soil mechanica
