Post-Flood Soil Deformation Monitoring Using Multi-Temporal Sentinel1 Data

In this paper, we are mainly interested in identifying and measuring the ground subsidence that occurred after the flooding of Oued EI Maadin tributary in Tunisia. For this purpose, we are adopting the Differential Interferometry Synthetic Aperture RADAR approach (D-InSAR) using a set of multi-temporal Sentinel1 SLC data. Furthermore, we are considering an offset tracking technique that provides assessments of the land subsidence movements. To do so, we are using two Sentinel1 GRD images that were acquired before and after the soil deformation event.
