摘要

Snow hazards, including heavy snowfall and freezing temperatures, pose significant risks to infrastructure, economic activities, and public safety, especially in regions with limited resilience. The Wilaya of Batna, Algeria, with its diverse topography and climate, is particularly vulnerable to such events due to its varying elevation and localized weather patterns. This study uses meteorological data from nine stations (2014–2023) to investigate snowfall variability, freezing hazards, and regional resilience. Elevated areas, such as Ichemoul and Arris, recorded substantial snowfall (average 144 cm and 134 cm annually), while lower altitude stations, such as Airport, experienced much less (~ 26 cm/year). GIS analysis identified high-risk zones, particularly Ichemoul and Arris, where snowfall exceeded 398.8 cm in extreme years, with temperatures falling below − 6 °C. Due to frequent and severe snowstorms, these areas face significant disruptions, especially on critical roadways, such as RN 77 and RN 31. Conversely, regions with more resilient infrastructure, such as Barika, experienced less impact. The study highlights the importance of developing effective snow management strategies, enhancing infrastructure, and implementing reliable monitoring systems to mitigate the socioeconomic impacts of snow hazards. Integrating GIS methodologies with snowfall data offers valuable insights for local authorities to better prepare for and mitigate snow-related disruptions.
