| Popis: | Lee, J.; Lee, W.; Lee, H., and Yoon, H., 2019. The settlement analysis of the saemangeum coastal area by the tide using D-InSAR. In: Lee, J.L.; Yoon, J.-S.; Cho, W.C.; Muin, M., and Lee, J. (eds.), The 3rd International Water Safety Symposium. Journal of Coastal Research, Special Issue No. 91, pp. 361-365. Coconut Creek (Florida), ISSN 0749-0208.In this paper, the ground settlement of the embankment located on the coast of Saemangeum is obtained using D-InSAR technique using SAR images. Sentinel-1B images with C-band were utilized and D-InSAR technique is performed using SNAP software. To derive the time series, six images are used from February 24, 2017 to March 21, 2018 to obtain ground settlement through D-InSAR technique. The accuracy of ground settlement is analyzed using GNSS constant monitoring station located in Saemangeum embankment. The RMSE value of the ground settlement obtained comparing the GNSS constant monitoring station data and D-InSAR techniques is accurate to 0.742mm. In addition, a relationship analysis of the ground settlement obtained usng D-InSAR techniques is conducted to analyze the change in the tide, one of the causes of the coastal ground settlement |
