Abstract

Summary

The Dnipro slopes in Kyiv represent an area of elevated landslide risk due to complex engineering- geological conditions, particularly the widespread presence of loess soils, steep terrain gradients, and the combined impact of meteorological and technogenic factors. The aim of this study was to zone the slopes based on their stability and relative landslide risk using geoinformation technologies. The methodological approach integrated a scoring system for slope stability factors (slope angle, soil type, moisture content via NDMI) with the classical risk assessment formula: Risk = Hazard × Vulnerability × Exposure.

The study combined geological data, remote sensing results (NDMI index from Sentinel-2), topographic plans, and information on buildings and engineering infrastructure into a unified GIS-based project. The Landslide Hazard component was evaluated using a weighted scoring system based on slope angle, soil classification, and moisture conditions. Risk values were normalized, and vulnerability and exposure were assessed for typical urban elements (buildings, roads, underground structures, green areas, etc.).

The results showed that 27.2% of the study area has a landslide probability exceeding 0.5, with 9% classified as high-risk zones. The resulting risk maps enable the localization of hazardous areas, support the optimization of monitoring systems, and assist in prioritizing engineering protection measures. The findings have practical value for urban planning, heritage preservation, and enhancing safety on the urbanized slopes of Kyiv.
