RT Journal Article T1 Monitoring soil sealing in Guadarrama River basin, Spain, and its potential impact in agricultural areas T2 Monitoreo de sellado del suelo en la cuenca del río Guadarrama, España, y su impacto potencial en áreas agrícolas A1 Pérez González, María Eugenia A1 García Rodríguez, María Del Pilar AB This study analyzes soil sealing and its repercussions in the loss of fertile soils, which are more appropriate for agriculture use. Also, soil sealing increases flood risk. The main objective is to estimate soil loss by sealing in the Guadarrama River Basin (Madrid, Spain) between 1961 and 2011. The combination of digital rocessing (Normalized Difference Vegetation Index (NDVI), principalcomponents and convolution filters) of satellite imagery with the digital terrain model helps to detect risk areas and allows quick updating of sealed soil mapping. The supervised classifications of the images were used to estimate the actual soil loss by sealing (9% in 2011) in the Guadarrama River Basin and the types and agrologic classes that have been lost. Soil loss occurs to a greater extent in highly permeable soils (sands) and in the most fertile soils. The main sealed soil associations are luvisols (alfisols), regosols (entisols) and cambisols (inceptisols).
