Rising relative sea level changes due to the ground subsidence in the coast can cause the risk of flooding in the low-lying areas. In this study, we estimated the subsidence along the coast for 50km length using time-series SAR Interferometry technique by acquiring Sentinel-1 SAR data of 78 scenes in descending and 81 scenes in ascending mode. Also, subsidence analysis at critical infrastructures such as Busan new port and Gimhae airport were conducted for analyzing the risk of flooding due to rapid subsidence.
