Özet

Recently, structures, built on reclamation sites in the Eastern Black Sea region are quite remarkable. As one of them, Senol Gunes Medical Park Arena Sport Complex, which is located in Akyazi town of Trabzon city, is one of the rare areas in Turkey. It is very important to monitor surface deformations on this type of unfamiliar and very expensive constructions for protecting human life and property and for taking necessary precautions in advance. Persistent Scatterer Interferometry (PSI), based on the analysis of time series of multiple Synthetic Aperture Radar (SAR) data, is an invaluable geodetic tool to measure surface deformations. So, in this study, it is aimed to monitor the surface deformations on the reclamation site between the dates 20/12/2016-28/01/2020 by StaMPS (Stanford Method for Persistent Scatterers)-PSI technique using 96 Sentinel-1 SAR images. For processing, integration of European Space Agency (ESA) SentiNel Application Platform (SNAP) and StaMPS programs are used. After processing, surface deformations are determined as annual velocities (millimeter(mm)/year(y)) of PS points in the reclamation area along the line-of-sight (LOS) direction between the values -9.7 mm/y and 3.9 mm/y with an average standard deviation of 0.7 mm/y. From the results, it is understood that the area demonstrates very heterogeneous deformations rates, which occur on both horizontal and vertical directions because of the diversity and being on the reclamation site of the structures.
