Transient deformation induced by groundwater change in Taipei metropolitan area revealed by high resolution X-band SAR interferometry

Quantifying groundwater exploitation induced subsidence in the Rafsanjan plain, southeastern Iran, using InSAR time-series and in situ measurements

“…Among ground and space-based geodetic methods used for measuring land subsidence (Abidin et al, 2008), space-borne interferometric synthetic aperture radar (InSAR) enables a unique imaging capability for the assessment of subsidence in response to fluid extraction from subsurface reservoirs (Galloway et al, 1998;Teatini et al, 2005). Differential Interferometric SAR (DInSAR) and advanced multi-temporal interferometry methods (e.g., permanent/persistent scatterer interferometry (Ferretti et al, 2001) and small baseline subsets (Berardino et al, 2002)) provide high spatialresolution (up to 25 cm) techniques for accurately (sub-centimetre to sub-millimetre accuracy) mapping the temporal and spatial distribution patterns of deformation (Casu et al, 2006;Ferretti et al, 2007;Manzo et al, 2012), allowing better characterizations of the elastic and inelastic properties of aquifer systems with high degrees of spatial resolution in both space and time (Canova et al, 2012;Ezquerro et al, 2014;Hoffmann et al, 2001;Rigo et al, 2013;Tomás et al, 2010a;Tung et al, 2016). InSAR measurements also help identify the influence of geological structures on spatial patterns of subsidence (Bawden et al, 2001;Burbey, 2008;Calderhead et al, 2011;Motagh et al, 2007;Stramondo et al, 2007).…”
