In this work, we investigate the temporal evolution of the ground deformation over the ocean-reclaimed area of the Shanghai megacity (China). To this aim, we performed an integrated SBAS-DInSAR analysis by benefiting from the availability of SAR data collected at C-band by the ENVISAT ASAR sensor, and at X-band by the COSMO-SkyMed and TerraSAR-X SAR constellations, spanning the overall time interval between 2007 and 2015. The joint exploitation of different SAR datasets and the knowledge of time-dependent models for the expected subsidence in ocean-reclaimed platforms is helpful to retrieve long-term displacement time series, thus allowing us to get new insights about the future evolution of the reclamation area settlements over the next years.

Abstract
In this work, we investigate the temporal evolution of the ground deformation over the ocean-reclaimed area of the Shanghai megacity (China). To this aim, we performed an integrated SBAS-DInSAR analysis by benefiting from the availability of SAR data collected at C-band by the ENVISAT ASAR sensor, and at X-band by the COSMO-SkyMed and TerraSAR-X SAR constellations, spanning the overall time interval between 2007 and 2015. The joint exploitation of different SAR datasets and the knowledge of time-dependent models for the expected subsidence in ocean-reclaimed platforms is helpful to retrieve long-term displacement time series, thus allowing us to get new insights about the future evolution of the reclamation area settlements over the next years.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
