 Cairo and Alexandria in Egypt  in the following two pages. Orange shows built-up areas in 2014. Shades of blue show permanent flooding due to sea level rise by 2050 and 2100 under low , medium  and high  greenhouse gas emissions scenarios. Darker colours for higher emissions scenarios show areas projected to be flooded in addition to those for lower emissions scenarios. The figure assumes failure of coastal defences in 2050 and 2100. Some areas are already below current sea level rise and coastal defences need to be upgraded as sea level rises , others are just above mean sea levels and they do not necessarily have high protection levels, so these defences need to be built . Blue shading shows permanent inundation surfaces predicted by coastal digital elevation model  and Shuttle Radar Topography Mission  given the 95th percentile K14/RCP2.6, RCP4.5 and RCP8.5, for present day, 2050 and 2100 sea level projection for permanent inundation  and RL10  . Low-lying areas isolated from the ocean are removed from the inundation surface using connected components analysis. Current water bodies are derived from the SRTM water body dataset. Orange areas represent the extent of coastal human settlements in 2014 . See Figure CCP4.7 for projections including subsidence and worst-case scenario projections for 2100.
