Abstract

Deformation monitoring of dam infrastructure and slopes surrounding the reservoir is essential for the maintenance and sustainable operation of the dam. Interferometric Synthetic Aperture Radar (InSAR) based monitoring is a promising remote sensing geospatial technology for effective monitoring of dam structures and reservoir rims with an accurate measurement of displacement at mm-level accuracy. In this study, the SBAS-InSAR method was used for data processing, and monitoring deformations at a dam and its reservoir rim, located in the Indian Himalayas. We found several sites around the reservoir having a noticeable mean line of sight deformation rate of 30 mm/yr to -30 mm/yr for ascending and +45 to -45 mm/yr for descending orbit. Results demonstrate a trend of deformation at the dam body and cumulative Line of Sight (LOS) deformation values reach up to -40 to +40 mm.
