Research object: geological environment and hazardous gravity processes of the Kyiv and Kaniv Dnieper regions. The purpose of the study: assessment of factors and forecasting of the landslide hazard of Kyiv and Kaniv Dnieper regions based on the integration of geological, geophysical, remote sensing methods, spatial analysis and deterministic modeling. A geodatabase of landslide processes of the Middle Dnieper has been created, which includes more than 400 objects and enables to display spatial information, store positional and non-positional characteristics of landslide objects, and perform spatial analysis and modeling operations. The role of lithological, stratigraphic, structuraltectonic and geomorphological factors in the formation of gravitational geological processes within the studied area was investigated on the basis of in-depth geological analysis, structural and morphometric studies, geoinformational analysis, systematization of actual material with the involvement of natural data. The GIS project of the landslide hazard of Kyiv and Kaniv Dnieper regions has been developed. A predictive model of the landslide hazard of the Kyiv and Kaniv Dnieper regions was built. Monitoring studies of the landslide hazard within the Kyiv region were carried out with the involvement of a complex of Earth remote sensing data and geophysical methods, on the basis of which the composition and structure of the most dangerous landslides and their dynamics were determined. A rational complex for local forecasting of landslide processes based on remote sensing data, geological, geophysical methods and infrared thermography was developed and tested within model sites in Kyiv (Botanic Garden, National Museum of the History of Ukraine, Lysa Gora, Lake Hlinka) and Kyiv region (Rzhishchiv, Grebeni). On the basis of mathematical modeling and application of Geostudio software, simulation of the stress-strain state of rock complexes within landslide-prone slopes was carried out.
