Determination of surface deformations of fill areas by satellite images

Trabzon Akyazi Stadium, Ordu – Giresun Airport are structures built on the sea embankment. Monitoring the surface deformations on these structures is of great importance for preventing the glitches that may occur in the structures. For this purpose, the PS-InSAR method was applied to SAR images obtained from Sentinel 1 satellites between 2020 and 2022 to determine the surface deformations in these structures built in the filling area. As a result of the application, it was observed that the movements of the points around Trabzon Akyazı stadium varied between -7 mm and 4 mm, and the surface movements at Ordu-Giresun Airport varied between -7 mm and 8 mm. It has been determined that the changes, especially in the coastal part of the filling areas, are negative, while in the terrestrial parts they are small and positive. Additionally, the results obtained revealed the usability of InSAR time series methods and SAR satellite images in continuous monitoring of structures on the fill area.
