Abstract :
We investigate the potentialities of differential SAR interferometry (DInSAR) to estimate the morphological changes of the channel bed induced by processes of erosion and deposition. The Cellina stream (North-East Italy) has been chosen as a test site. The stream has a braided channel morphology with a gravel bed. A set of ERS-1/2 SAR images acquired in this area has been interferometrically processed. The DInSAR analysis enabled areas of erosion and sedimentation to be mapped.
