Evaluation of the potential of InSAR time series to study the spatio-temporal evolution of piezometric levels in the Madrid aquifer

“…We use the InSAR time series processed in Ezquerro et al (2014), covering the period April 1992 to September 2010. These data were processed with the PSP-IFSAR technique (Costantini et al, 2008) to calculate the radar line-ofsight (LOS) displacement temporal evolution of each Persistent Scatterer (PS).…”

“…The Tertiary detritic aquifer of Madrid (TDAM), with an average thickness of 1500 m and a heterogeneous, anisotropic structure, supplies water to Madrid, the most populated city of Spain (3.2 million inhabitants in the metropolitan area). Besides its complex structure, a previous work focused in the north-northwest of Madrid city showed that the aquifer behaves quasi elastically trough extraction/recovery cycles and ground uplifting during recovery periods compensates most of the ground subsidence measured during previous extraction periods (Ezquerro et al, 2014). Therefore, the relationship between ground deformation and groundwater level through time can be simulated using simple elastic models.…”

Interpolation of GPS and Geological Data Using InSAR Deformation Maps: Method and Application to Land Subsidence in the Alto Guadalentín Aquifer (SE Spain)

“…InSAR has been used to detect and monitor many areas of subsidence produced by groundwater exploitation [10][11][12], deduce aquifer hydraulic properties [13][14][15] and estimate hydraulic head evolution [16].…”

Regional subsidence modelling in Murcia city (SE Spain) using 1-D vertical finite element analysis and 2-D interpolation of ground surface displacements

“…A-DInSAR techniques provide the displacement estimates, the velocity map and the displacements time series for the whole observation period along the satellite Line of Sight (LOS). These techniques have been effectively used to the subsidence monitoring as shown in many published works (Bru et al, 2013;Cascini et al, 2013;Ezquerro et al, 2014;Modoni et al, 2013;Sanabria et al, 2014;Tomás et al, 2014). Specifically, in the present work, the DInSAR processing of C-band SAR images achieved through the Stable Point Network (SPN) technique (Arnaud et al, 2003) for the period 1995-2008(Terrafirma, 2008 has been used.…”
