Sea level rise (SLR) has become a challenging global issue especially in coastal areas that host a large percentage of the world population. The phenomenon of sea level rise is expected to result in increasing coastal inundation and erosion. The physical, environmental and human processes including economic systems and social structures in coastal regions, which are densely populated, may be disrupted. Yanbu Industrial city is located at the coast of Red Sea in the Western part of Saudi Arabia. The city houses a lot of investments running to billions of Riyals. Unlike most coastal areas in the world which are densely populated, the population of Yanbu Industrial City is moderate. Despite the control measures on population by the Royal Commission for Jubail and Yanbu, the population of the city in rapidly increasing in recent time due to industrial activities. This paper attempts to examine the different scenarios of the sea level rise and its consequences on Yanbu Industrial City. Analyses of these scenarios were carried out using Digital Elevation Model (DEM) from Shuttle Radar Topography Mission (SRTM) with high resolution remote sensing data (for visualization) within Geospatial Information System (GIS) environment. This study uses a minimum scenario of SLR of 1m by the year 2100. Tاhe result is overlaid on the demographic and land use data of the city to estimate the likely impact on land use and population of the area. The results show that the industrial city is vulnerable to sea level rise.
