- Abstract
Environmental hazards invariably lead to significant human and financial repercussions, underscoring the crucial need to thoroughly investigate and recognize hazardous areas. Recognizing the importance of this matter, this study focuses on identifying regions susceptible to natural hazards within Roodehen's urban area. To achieve the objectives, a variety of data sources, including a digital model with a 30-meter height resolution, a geological map at a scale of 1:100,000, a topographic map at a scale of 1:50,000, and additional information layers were harnessed as primary research tools. The research method integrated multiple analytical tools, incorporating a digital model with a 30-meter height resolution, a geological map at a scale of 1:100,000, a topographic map at a scale of 1:50,000, and various information layers. ArcGIS software served as a pivotal component in data analysis, bolstered by the fuzzy logic model and the ANP model. The approach encompassed a multi-step process commencing with the utilization of the integrated fuzzy logic and ANP model, driven by diverse parameters, to pinpoint areas susceptible to flood hazards, amplitude movements, and earthquake vulnerability. Consequently, a comprehensive hazard map of Roodehen's urban area was formulated based on the obtained outcomes. The study underscores Roodehen's urban area as being at a heightened risk of natural hazards. Particularly, the western and northern regions exhibit elevated vulnerability due to their proximity to fault lines, earthquake centers, and steep slopes, making them susceptible to slope movements and earthquake hazards. Conversely, the central parts of the region, situated in close proximity to the river with low slopes and altitude, face a higher risk of flooding, and demonstrate significant earthquake vulnerability.
