Analysis of the Makran Coastline of Iran’s Vulnerability to Global Sea-Level Rise

The SE coast of Iran is great economic and environmental importance. Global climate change affects this coastline through sea level rise (SLR), compounded by a decrease in sediment budgets coastal areas. This study developed Coastal Vulnerability Index (CVI) for the using satellite, instrumental field data. Eight risk variables were defined: slope, regional elevation, mean tidal range, significant wave height, rate relative sea-level change, shoreline sensitivity socio-economic sensitivity. was divided into 27 segments based on geomorphic, socioeconomic traits. categorized their vulnerability to each factor CVI. resulting maps highlighted segment SLR. Approximately 50% comprised mostly rocky shores, which are less vulnerable 33% length, including sandy beaches, flats mangrove forests, determined be highly 12% moderately vulnerable. Population centers infrastructure ranked as highly-to-moderately high low-lying areas, such lagoons mangroves, western part Iranian Makran. Proper management mitigation plans essential future protect societies environments.
