Abstract
Summary
The area of research interest is an activated landslide located near the village of Topola, Kaliakra municipality and it is manifested in the front of an ancient stabilized landslide “Kalkan tepe”. The combined GNSS and InSAR applications for landslide monitoring in the north of the Black Sea coast, Bulgaria conducted in the past 3 years aimed to contribute to the complex geodetic and geological research. Due to their high precision GNSS are very appropriate for investigating geodynamic processes. The InSAR technique is a remote sensing technique mostly applied for the detection and monitoring of earth surface deformations with wide spatial coverage. In November 2020, an aerial drone survey of the Thracian Cliff landslide was performed using UAS technology to mapping surface models of the study area. The ability to observe many points (pixels), including the whole object, as well as their behavior over time, allows the development of models of the deformation process and facilitates the solution of a number of tasks on forecasting and geohazard. The application of contemporary technologies for monitoring greatly facilitates the monitoring of landslide deformation processes.
