Abstract

Landslides, multi-scale ground movements, significantly impact human lives and ecosystems, posing a major threat to rapidly growing regions. Effective sustainability planning is essential to mitigate these risks and support informed urban development and decision-making. This study focuses on assessing landslide hazards in Fuman County, Gilan Province, located in northwestern Iran. The research employs the Analytical Hierarchy Process (AHP) to classify landslide susceptibility, integrating various triggering factors such as topographic, geological, climatic, and anthropogenic variables. Data collection involved field surveys and analysis of remote sensing images, providing a comprehensive understanding of the region's risk profile. To ensure the accuracy of the results, the susceptibility map was validated using pixel-based assessments and remote sensing data fusion. These methods enhanced the precision of the hazard analysis, ensuring reliable identification of high-risk zones. Findings indicate that the most vulnerable areas are concentrated in the southern part of Fuman County, where the Alborz mountain range contributes to heightened susceptibility. This region's geological characteristics, combined with human activities and climatic conditions, exacerbate landslide risks. This study underscores the importance of hazard mapping and risk assessment in guiding sustainable development and disaster management strategies.The insights provided by this research can inform policymakers and urban planners in implementing effective mitigation measures to reduce potential damage and enhance resilience in landslide-prone areas.
