DInSAR measurements of ground deformation by sinkholes, mining subsidence, and landslides, Ebro River, Spain

Differential Interferometric Synthetic Aperture Radar (DInSAR) has been applied to detect and measure ground deformation in a stretch of the Ebro River valley (Spain) excavated in salt-bearing evaporites. The capability of the Small Baseline Subset (SBAS) DInSAR technique to detect ground displaceme...
