Scientific paper

In this paper an experiment aimed at evaluating the potential of SAR systems in monitoring hydrological parameters in a large watershed of a semi-desert area was described. Remote sensing and ground truth measurements were carried out in Morocco, within the framework of the EC project FLAUBERT (Flood in Arid Units By Earth Remote Techniques). ERS/C-band SAR and JERS/L-band SAR images collected from October 97 to June 99 were analyzed. In spite of the very low changes in space and time, the spatial and temporal analysis of L- and C-band backscattering showed the capability of SAR to point out yearly variations due to vegetation cycle and rain events and to map semi-arid vegetation. By using interferometric coherence a separation of several soil and vegetation classes in the same image was obtained.
