“…Different prediction models based on either a conceptual, empirical or a physically based framework can be implemented (Wischmeier and Smith, 1978;Morgan et al, 1998;Parsons et al, 2004). Direct measures are based on the implementation of dynamic and volumetric methods: the first type refers to experimental erosion plots (Stroosnijder, 2005;Desir and Marín, 2007) and the second to erosion pins and microtopographic profiles (Benito et al, 1992;Sirvent et al, 1997).…”

Abstract. Anatomical changes of exposed tree roots are valuable tools to date erosion events, but the responses of diverse species under different types of erosion need still to be studied in detail. In this paper we analyze the histological changes that occur in roots of Scots pine (Pinus sylvestris L.) subjected to continuous denudation. A descriptive and quantitative study was conducted in the Senda Schmidt, a popular trail located on the northern slope of the Sierra de Guadarrama (Central Iberian System, Spain). Measurement of significant parameters allowed the moment of exposure of the roots to be identified. These parameters were: a) width of the growth ring; b) number of cells per ring; c) percentage of latewood and d) diameter of cellular light in earlywood. A one-way analysis ANOVA was also carried out in order to establish statistically significant differences between homogeneous groups of measurements in pre-exposed and exposed roots. Based on these analyses, Scots pine roots show a remarkable anatomical response to sheet-erosion exposure. Increased growth in the ring is accompanied by a slight reduction of the cell lumina of the earlywood tracheids. At the end of the ring, several rows of thick-walled tracheids define latewood tissue and visible annual borders very clearly. Furthermore, resin ducts often appear in tangential rows, increasing resin density in the tissue. All of these indicators made it possible to determine with precision the first year of exposure and to estimate precisely sheet erosion rates.

“…The results offered by these methods show equally very high erosion rates on the silica sand gullies, compared with other badland areas of Spain [6,7]. After intense storms, the fillings of local roads with sand, which make necessary the cleaning of this sand, allow a quantification of the sediment yield from the silica sand gullies.…”

A characterization and quantification of the geomorphic activity of three scenarios of silica sand slopes of Central Spain (Segovia and Guadalajara province), is being carried out: (a) silica sand slope gullies; (b) non-reclaimed (abandoned) silica sand mines; (c) abandoned silica sand mines reclaimed with a geomorphic approach. On the silica sand slope gullies, gathered data point at very high rates of erosion and sedimentation, since runoff and hydric erosion occurs on them almost instantaneously after precipitation. When no reclamation is made, silica sand mines evolve like 'natural' gullies, and they show higher rates of hydric erosion than them. The erosion of non-reclaimed silica sand mines produces severe on and off site environmental impacts. When reclamations are made based on geomorphic approaches, runoff and soil erosion can be reduced to the minimum at the pediment areas, whereas the highwalls can maintain a geomorphic activity which integrates them into the landscape. The understanding of these scenarios is allowing improving new reclamation plans on silica sand and kaolin mines of Central Spain, concerning their topographical and watershed design, and layout of the reconstructed terrain (waste dumps, surficial deposits, and topsoil). The latter example shows a desirable framework of collaboration between mining companies, protected areas managers and universities.

“…La distribución irregular de las precipitaciones, donde alternan máximos pluviométricos con eventos de tormenta con periodos de escasa o nula precipitación, hacen que la estabilidad de estos suelos sea baja y las tasas de erosión altas (Gutiérrez et al, 1995;Sirvent et al, 1997;Marín y Desir, 2004). Por otro lado, las propiedades fisico-químicas de estos suelos condicionan la presencia de procesos de piping y de hinchamiento y consecuentemente la presencia de las diferentes morfologías y mecanismos actuantes (Campbell, 1989).…”

“…El modelado en esta área es muy dinámico y cambiante debido principalmente a los procesos de erosión hídrica. Para conocer el alcance de la misma debido a la acción de la escorrentía superficial se instalaron Parcelas Experimentales para el estudio de la erosión hídrica sobre las arcillas miocenas de la Formación Tudela (Gutiérrez et al, 1995;Sirvent et al 1997;Marín y Desir, 2004). Mediante esta técnica dinámica se ha podido conocer los valores de pérdida de suelo por erosión hídrica desde el año 1993 en que se instalaron las Parcelas, resultando en una media anual de 32 Tm/Ha/año (Tabla 3).…”
