Abstract

In order to make a connection between West and East Azerbaijan embankments a bridge with the length of ~1300 m and width of ~30 m has been constructed in the late 2009s. This bridge has an important role in the development of tourism, transportation and trade in the area. The difference between the DEFORMATION rates of the embankments on both sides of the bridge may seriously damage the bridge itself, so it is very important to accurately monitor them in space and time in order to assess the state of the bridge concerning DEFORMATIONs. Interferometric Synthetic Aperture Radar (InSAR) is a powerful geodetic technique for precise DEFORMATION monitoring in space and time due to its extensive area coverage, high spatial (1-20 m) and temporal resolution (11-46 days) and acceptable accuracy (cm to mm level). Advanced interferometric time-series techniques such as Small BAseline Subset (SBAS) approach is a valuable tool for structural monitoring and provide DEFORMATION maps with millimeter accuracy. In this study, this technique has been applied on a dataset of 58 SAR images acquired by ENVISAT, ALOS and TerraSAR-X (TSX) satellites from 2003 to 2013 to monitor spatio-temporal evolution of ground DEFORMATION on the embankments. The InSAR results show deflation on both embankments of the bridge is occurred with peak amplitude of ~50 mm/year in the line of sight direction.
