Abstract

The present work sheds light on four major problems, which are considered at present threatening the Nile Delta socio­ economic development. These problems are seismicity hazard due to neotectonism, coastal marine erosion, sea level rise, and subsidence. The Nile Delta is a product of migration of the Cenozoic deltas, mostly northeastward, along the Pelusium line. The areal extent of the Delta is defined by major structural components, revealing the influence of plate scale phenomena. They are currently active and dynamic as a part of the deformation of the incoherent African plate and the structurally dissected Mediterranean. The Nile Delta, by its location along the northeast corner of the African plate and the southeast of Mediterranean Sea, is expected to be affected by the structural elements and tectonism of these two regions. It is often thought and described in literature as part of the passive leading edge of Africa. A fact that would lead to a further implication to compare the Nile Delta with deltas along the passive margin of the Atlantic, especially those of the Gulf of Mexico and the Niger delta. This comparison appears here unjustifiable. The receiving basin of the Nile Delta is the shrinking Mediterranean Sea. On the contrary the Atlantic Oceans, including north and south basins, are extensional basins. Additionally, the borders of the Atlantic are extensional ones while the North African border is a compressional type at the present since the Late Mesozoic. On other hand, deltas along the Atlantic borders have dominance of structures parallel to their Atlantic shores, with minor dissecting elements. The previous apparent difference confirms the distinction of southeastern Mediterranean style of the Nile Delta from the Atlantic passive leading edge style.
