Abstract
The work was done in a hydrological unit of the river Jarama province of Guadalajara, Spain, the area is extensively studied by several research projects that integrates the use of representative soil of any semiarid Mediterranean to Spain, his analysis can infer results fully extrapolated other similar regions. The objective was to determine the spatial dynamics of changes in land use occurred during the last three decades in an area of 23,027 ha. Land cover were obtained from two Landsat images from 1984 and 2013. A methodology that combines the use of digital techniques and visual classification from satellite imagery, geographic information systems (GIS) and remote sensing was used. The method employs the analysis of a cross-tabulation matrix at different levels to distinguish those changes resulting from systematic transitions to conduct more comprehensive assessments of the most significant changes in the territory. The results confirm that the major changes in the landscape are the result of the development of canopy cover (FCC) of 20-70% and permanent pasture with a positive net balance of 152.24% and 473.11%. Negative net results as unproductive, tree crops and vineyards dryland pasture wasteland change, Fcc> 70% and irrigated crops were also obtained. Changes Indoor Air suggest that the basin has changed greatly by the volume of runoff and sediment production.
