Description :
Differential Interferometric Synthetic Aperture Radar (DInSAR) has been applied to detect and measure different types of natural and human-induced ground deformation in a stretch of the Ebro River valley (Spain) excavated in salt-bearing evaporites. A discussion on the advantages and limitations of the applied technique is provided by comparing the SBAS-DinSAR results with the data on sinkhole and landslide distribution and activity previously gathered by traditional geomorphological investigations (mainly aerial photograph interpretation and field surveys).
