The impact of wildfires and of restoration actions on soil organic matter (SOM) content and structure was studied in a soil under pine (Pinus pinea) from Doñana National Park (SW Spain). Samples were collected from burnt areas before (B) and after post-fire restoration (BR) and compared with an unburnt (UB) site. Analytical pyrolysis (Py-GC/MS) was...
Water repellency (WR) and aggregate stability (AS) are two soil properties generally modified after burning which show several hydrological and soil functioning consequences and may be used as indices for assessing burn severity. Both properties are strongly related and have major impacts on soil functioning and post-fire hydrologic and geomorpholo...
Fire induced soil water repellency (WR) is controlled by many different factors (temperature reached, amount and type of fuel, etc.). Soil properties may determine the occurrence and intensity of this property in burned soils. The objectives of this paper are to make advances in the study of soil properties as key factors controlling the behaviour...
Los incendios forestales producen una serie de efectos sobre el suelo que dependen tanto de factores intrínsecos (sus propiedades físicas y químicas), como de la intensidad del incendio y de la vegetación. La principal característica post-incendio es la drástica disminución de la cobertura vegetal del suelo, que lo sitúa en un estado vulnerable fre...

Algunos de los cambios más evidentes del fuego en el suelo son la disminución de la cobertura vegetal y de la cubierta de residuos orgánicos del horizonte superficial. Como consecuencia, se produce un incremento del riesgo de erosión del suelo debido al aumento de la tasa de escorrentía y al efecto del impacto directo de las gotas de lluvia. La pre...

Wildfires are a common feature of Mediterranean ecosystems due to
environmental factors and anthropic influence, especially in those areas
where land use change and the development of touristic infrastructures
are more intense. Wildfires induce a series of soil changes affecting
their physical and chemical properties and the hydrological and erosiv...
La repelencia al agua es una propiedad de los suelos, que reduce su capacidad de infiltración. La repelencia al agua del suelo también afecta a la evaporación, la erosión, la estructura y el comportamiento hidrológico de los suelos. Esta propiedad ha sido observada en diferentes regiones, climas, tipos de suelo y de vegetación. En condiciones natur...
Fire induced soil water repellency (WR) is controlled by many different factors (temperatures reached, amount and type of fuel, etc). Some soil properties may determine the occurrence and intensity of this property in burned soils. In this research, experimental laboratory burning have been carried out using soil samples from different sites and co...
The main objective of this research is to study the effects of particle size and soil moisture on water repellency (WR) from hydrophobized sand samples. Quartz sand samples were collected from the top 15 cm of sandy soils, homogenised and divided in different sieve fractions: 0.5 - 2 mm (coarse sand), 0.25 - 0.5 mm (medium sand), and 0.05 - 0.25 mm...
The effects of different fire intensities on physiochemical soil properties have been studied in this research. The experiment was conducted in a eucalyptus forested area near the Namadgi National Park (ACT, Australia), and four fire intensities were achieved by adding different amounts of fuel load: 0 kg m− 2 (control), 2 kg m− 2 (low fire intensi...
Numerous studies along the northern Mediterranean borderland have documented the use of shellfish by Neanderthals but none of these finds are prior to Marine Isotopic Stage 3 (MIS 3). In this paper we present evidence that gathering and consumption of mollusks can now be traced back to the lowest level of the archaeological sequence at Bajondillo C...
Mediterranean soils under heathland are often shallow, with low capacity for water storage, and a high risk of erosion. In this context, recurrent wildfires can negatively affect their chemical and physical properties. Very little research has been carried out concerning the long-term variations on the ground surface after burning. The behaviour of...
Water repellency (WR) from fire-affected soils can affect infiltration processes and increase runoff rates. We investigated the effects of fire-induced changes in soil WR and the related soil hydrological response after one of the largest wildfires in Spain in recent years. The vertical distribution of WR in soil profiles was studied under oak and...
Forest fires are recurrent phenomena in the Mediterranean area and are one of the main causes of changes in Mediterranean ecosystems, increasing the risk of soil erosion and desertification. Fire is an important agent which can induce important changes in the chemical and physical characteristics of soils. Burning severity can modulate the recovery...

Soil water repellency is usually modified after wildfires by the combustion of soil organic matter and plant residues, and is considered to be the cause of important changes in the hydrological response of burned soils. In this research, the interactions between burning temperature, soil water content, water repellency and stability of aggregates h...
Many authors have reported increased water repellency in fire-affected areas. Research on post-fire soil erosion show a range of results. Many authors have found increased soil erosion and runoff rates after fire, due to factors as loss of vegetation canopy, low structural stability of soils and enhanced runoff flow on soil surfaces affected by fir...
A model that simulates the dispersion of chemical/radioactive and oil spills in the Strait of Gibraltar has been developed. Water currents over the Strait have been obtained from a hydrodynamic model. Computed tides and residual currents have been compared with observations in the area. The dispersion model, based on a particle-tracking technique,...
GISPART (GIbraltar Strait PARticle Tracking model) is a three-dimensional particle-tracking code that simulates the dispersion
of radionuclides in the Strait of Gibraltar. It consists of a hydrodynamic module that is run off-line to determine tidal
constants and residuals in the domain. This information is stored in files that are read by the dispe...
