Assessment of Avalanche Risk Using GIS in Mountain Areas - Case Study Arieșeni, Alba County

Avalanches represent a significant threat in mountainous regions (Arieseni, Alba County), especially in areas without vegetation that contributes to the stability of the snowpack. This study proposes a GIS-based methodology for identifying and assessing avalanche risk, utilizing Corine Land Cover (CLC) vector data, digital elevation models (DEM), and proximity analysis to built infrastructure. Through raster reclassification and multicriteria integration, a detailed risk map was created, providing a useful tool for managing exposed areas and disaster prevention.
