Abstract :
The Differential SAR Interferometry (DInSAR) technique has been applied to a test site located near Vauvert (France). A subsidence phenomenon has been previously observed by leveling. Precise monitoring of the phenomenon is needed in relation with deep (more than 1 km) exploitation of underground salt by solution mining, in order to constrain further geomechanical modeling studies for a better knowledge of its evolution. The InSAR measurements has been compared to the available leveling data.
