Assessment of Coastal Inundation due to Sea-Level Rise along the Mediterranean Coast of Egypt

If the rising sea level due to climate change proceeds in the future with the rate observed in the past four decades, it could inundate some coastal lowlands. The aim of this paper is to assess future risk of sea-level rise (SLR) on the Nile delta of Egypt located along the Mediterranean Sea. Digital Elevation Models (DEMs) are verified, against ground control points, and used to identify areas susceptible to inundation due to future SLR. Analysis of DEMs maps and cross-shore profiles has identified locations that are vulnerable to SLR including coastal wetlands, agriculture areas, and urban neighborhoods. The results have revealed that about 7% of the Nile delta area is at risk of inundation due to future SLR. This information could be used by coastal zone managers in planning and protection of coastal areas.     

Rudists (Bivalvia) from a Cretaceous Platform in Northern Egypt:Taxonomy and Paleobiogeography

New well-preserved rudist materials come from the Barremian–Turonian marine formations in the Yelleg, Minsherah, Maaza, and Raghawi sections in North Sinai, northern Egypt. There, 17 discovered rudist species belonging to 13 genera and seven taxonomic families are described in detail as follows: Eoradiolites plicatus (Conrad), Eoradiolites liratus (Conrad), Praeradiolites ponsianus (?Archiac), Archaeoradiolites sp., Bournonia africana Douvillé, Bournonia fourtaui Douvillé, Biradiolites lombricalis (?Orbigny), Biradiolites zumoffeni Douvillé, Radiolites lewyi lewyi Parnes, Radiolites sauvagesi (?Hombres-Firmas), Durania arnaudi (Choffat), Toucasia carinata (Matheron), Toucasia sp., Neocaprina raghawiensis Steuber and Bachmann, Sellaea sp., Ichthyosarcolites sp. and Horoiopleura sp.. The Cenomanian deposits in the northern Eastern desert of Egypt only contain E. liratus. The domination of the Cenomanian rudist species in North Sinai, however, is attributed to changes in the platform, which passes mainly from carbonate in the north to siliciclastics in the south. The presence of Horiopleura sp. in the late Barremian–early Aptian deposits is documented for the first time, which suggests the expansion of taxa of the genus Horiopleura Douvillé to North Sinai during this interval. The age of the rudist species is documented from the late Barremian–Turonian formations, with their geographic distribution in the Mediterranean region considered..
