In this paper 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 on the this area has been interferometrically processed. The DInSAR analysis enabled areas in erosion and sedimentation to be mapped.

Abstract
In this paper 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 on the this area has been interferometrically processed. The DInSAR analysis enabled areas in erosion and sedimentation to be mapped.
