Monitoring dynamiki ruchów powierzchni osuwisk w warunkach zmiennego poziomu wód gruntowych z wykorzystaniem reflektorów radarowych

The main objective of the presented analysis was to investigate to what extent even minor changes in the hydrological and hydrogeological environment affect the changes in thedynamicsoflandslidesurfacedisplacement.Theresearchwascarriedoutforselectedmonitored landslides, which, in addition to the in-depth monitoring devices, were equipped with corner reflectors suitable for satellite radar interferometry measurements. The high temporal resolution of the interferometric data allowed demonstrating the existence of a relationship between the speed of surface movements and slight changes in the depth to the groundwater table. The analyses were performed for five landslides, which also showed a high dependence of these compounds on the geological structure of the landslide and its substrate.
