Comprehensive processing of InSAR radar images and GNSS measurements to determine deformations of the Kaniv HPP dam

Нестеренко, С.В.

Military aggression in Ukraine and military actions led to numerous technogenically loaded and ecological disasters in a third of the territory. Buildings and structures of various purposes were damaged, partially or completely destroyed, including roads, railways, water and sewage systems, oil and gas pipelines, etc. There are constant technogenically loaded threats to critical and military infrastructure, including energy facilities and hydraulic structures. In this regard, monitoring of HPP dams, in particular by geodetic and geotechnical methods, is relevant. In the conditions of war, remote methods are especially relevant. To date, systems for continuous monitoring of their displacements and deformations have been installed on some dams of Ukrainian hydropower plants. At the Kaniv HPP, monitoring of spatial displacements and deformations of dams is performed periodically by traditional geodetic methods (high-precision leveling, GNSS surveying, linear-angular measurements). The periodicity of these measurements ranges from 3 to 12 months. This approach to determining displacements and deformations of dams does not provide continuous spatial information about dams and a satisfactory frequency of measurements over time. One of the ways to eliminate these shortcomings is the complex processing of the results of automated systems for monitoring displacements and deformations of the dam with remote sensing of these processes using interferometric synthetic aperture radar (InSAR). The aim of the study is to comprehensively process InSAR radar images and GNSS measurements to determine the vertical deformations of the Kaniv HPP dam. The object of study is the monitoring of the Kaniv HPP dam using satellite radar data and GNSS data from the network of the stationary system for monitoring the spatial movements of the Kaniv HPP structures.
