Abstract
Background and Objectives: The vast country of Iran is always exposed to various land hazards. These hazards include earthquakes, subsidence, floods, extreme cold and heat, etc., which can cause serious damage to infrastructure, especially the railway network, and cause a lot of costs to the country's railways, while also causing life-threatening risks to passengers. Therefore, it is important to study these natural hazards in the railway, especially the Zagros railway region, which is located in a mountainous region and has seen many accidents. The aim of this study is to study the impact of some hazards on the railway network.
Methods: For this purpose, all layers of slope, elevation, population, rainfall, river, geology, land use, soil type, and fault are analyzed after being fuzzified using the AHP method and performing an overlay analysis in GIS.
Findings: After overlapping the fuzzy layers, the research findings indicate high to medium risk in the study area.
Conclusion: The results show that this area is one of the most critical areas because about 740 square kilometers of the railway network within a 2-kilometer radius is at moderate to severe risk and requires better management and more attention from the authorities. The results of past risks also confirm the performance of this method.
