Coastal Vulnerability Index of the Nile Delta

Most vulnerable area to sea level rise along the northern Mediterranean coast of Nile Delta is about of 300 km of the coastline was evaluated for seventeen LANDSAT images used. In this paper all available spatial factors (ten factors): geology, geomorphology, topography (elevation above mean sea level), slope, erosion/accretion patterns (shoreline change), mean sea level rise, and coastal protection were incorporate and ranked to develop an Improved coastal vulnerability index (ICVI). That ICVI was developed and used to assess the vulnerability of the coastline of the Nile Delta of Egypt to expected future sea level rise.

The produced index was classified into four levels of vulnerability: low, moderate, high, and very high. About 29.64% of 300.8 km of mapped shoreline classified as very high in vulnerability, whereas 2.77% is highly vulnerable, 41.56% is at moderate vulnerability, 3.2% classified as low vulnerability, and 22.84% is a very low vulnerability. Vulnerable hotspots are located mainly along most of Nile Delta coast, southeastern parts of Abu Qir, and southwestern parts of Alexandria city. The remaining coastal areas classified as low to moderately vulnerable (like Alexandria, Rosetta, and New Damietta Cities).
