City-Based Risk Assessment of Sea Level Rise Using Topographic and Census Data for the Turkish Coastal Zone

Abstract

Turkish coastal zone elevation to sea level rise was illustrated using a digital elevation model and methods in a geographical information system. It was intended to determine several parameters such as population, settlements, land use, wetlands, contribution to national agricultural production, and taxes at risk using high-resolution Shuttle Radar Topography Mission topographic, orthorectified Landsat Thematic Mapper Mosaics and census data with geographical information system methods within 0- to 10-m elevation of the national level. All parameters were examined for coastal cities, coastal districts, settlements, and villages' status. It was found that approximately 7,319 km2 of land area lies below the 10-m contour line in Turkey and is, hence, highly vulnerable to sea level rise. Twenty-eight coastal cities, 191 districts, and 181 villages or towns are located below the 10-m contour line in the study area. The findings suggest that the Turkish Ministry of Environment should declare new areas protected and develop special environmental programs at the national level.
