Abstract

Landslide processes play a crucial role in geomorphological dynamics, significantly influencing the morphology of mountainous regions. Their impact is particularly evident in areas characterized by intense tectonic activity, such as the mountainous regions of Uzbekistan, where landslides dominate transformations of the Earth’s surface. In inhabited mountainous zones, these phenomena cause significant damage and present severe risks to human life and property. Advances in remote sensing technologies and Geographic Information Systems (GIS) over the past two decades have greatly enhanced understanding of landslide processes. Building upon these developments, this paper presents a comprehensive framework for analyzing landslide dynamics at the slopes surrounding the Charvak Reservoir. The proposed methodology combines the relief plasticity technique with advanced remote sensing tools and GIS approaches. Drawing insights from prior studies and existing cartographic resources focused on lithodynamic flow analyses, it provides a robust foundation for identifying and predicting potentially hazardous landslide-prone areas. Additionally, the study explores key methodological aspects concerning territorial zonation based on varying levels of landslide risk. At its core lies an investigation of morphometric characteristics extracted from Digital Elevation Models (DEM/SRTM), complemented by the application of the second derivative method to topographic maps. From a practical standpoint, the results underscore the effectiveness of modern GIS applications and remote sensing data sets—including aerial and satellite images from Landsat—for accurate landslide mapping and assessment of their activity. As part of the research efforts, a detailed map of landform plasticity for the study region was created and converted into a digital format through geographic information systems (GIS). Furthermore, the analysis of lithodynamic flows within recognized landslide areas enabled reliable determination and delineation of morphological boundaries associated with distinct landslide flows.
