Abstract :
An experiment aimed at evaluating the potential of synthetic aperture radar (SAR) in monitoring hydrological parameters in semi-desert areas was carried out within the framework of the EC project FLAUBERT (FLood in Arid Units By Earth Remote Techniques). In spite of the very low changes in space and time, the analysis of backscattering and interferometric coherence showed the capability of SAR to separate a few land classes and to point out yearly variations due to vegetation cycles
