Abstract

Piping erosion is a relatively common process in semiarid areas and has a series of negative effects associated to it, such as the degradation of crop fields. The present work analyses the case of the Aguarales de Valpalmas (Zaragoza), studying the evolution of cultivated areas since mid-twentieth century to the present from a planimetric and volumetric point of view. The application of GIS tools shows changes in their distribution, quantifying a superficial loss of 10% compared to their situation in 1957. On the other hand, the application of automated digital photogrammetry techniques allowed us to reconstruct the historical landscape and the comparison between models, obtaining a loss of soil of about 2,600 m3. This type of study improves magnitude estimation of erosion processes and their effects on agricultural land.
