Abstract
The consideration is given to the results of application of a complex of geophysical methods for the purpose of local forecasting of landslide hazards within the flooded quarry, named Glynka Lake (Kyiv, Ukraine). One of the regions of active development of landslides in Ukraine is Kyiv, where the mass movement processes have significant impact on people’s livelihoods and infrastructure. These landslide processes occur on slopes of different structure and morphology. Currently, the territory of the starboard side of the Glynka Lake is one of the most dangerous landslides in Kyiv and poses a threat to infrastructure facilities on the towards Akademika Filatova Street and Mendeleeva Street. Electrical Resistivity Tomography, Self-potential, Infrared Thermography and ground penetrating radar (GPR) techniques were applied to investigate the lithostratigraphic sequences, the geometry of landslide body and potential mass movement. These methods allowed to define the composition and structure of the landslide, as well as to identify moisture or a seepage zones on the landslide slope. GPR method was showed borders between different deposits layers and possible surface of rupture. This study demonstrates the potential of using an integrated approach for landslide characterization in the regions with complex geological structure.
