APPLICATION OF INSAR TECHNOLOGY FOR MONITORING OF THE SHERUBAY-NURA RESERVOIR DAM

https://doi.org/10.48498/minmag.2026.257.9.008

This paper investigates the potential of multi-temporal satellite radar interferometry for monitoring the deformation state of the Sherubay-Nura Reservoir dam. Spatial and temporal displacements of the structure were assessed using the SBAS-InSAR approach based on Sentinel-1 satellite imagery. Trihedral corner refl ectors were employed to improve the reliability of interferometric measurements by ensuring stable identifi cation of reference points. The analysis enabled the identifi cation of localized deformation zones and the assessment of displacement rates and their temporal evolution, demonstrating the eff ectiveness of integrating InSAR technology with corner refl ectors for the remote monitoring of hydraulic structures.
