Abstract :
Interferometric Synthetic Aperture (InSAR) observations acquired by the Envisat satellite in a descending orbit during 2004-2007 are used to study land subsidence caused by groundwater over-exploitation in Mashhad Valley, northeast of Iran. Motagh et al (GJI 2006) presented a preliminary analysis of the subsidence in this area using a few interferograms covering the 2003-2005 periods. This paper utilizes ENVISAT data to retrieve the temporal evolution of the surface deformation in Mashhad.
