HYDRAULIC EFFECT OF WAVES ON THE NORTHERN COAST AND SUBMARINE SAND BARS CHARACTERISTICS

Abstract

The instability of the Nile Delta Coast in terms of erosion and accretion has been documented since the beginning of the present century. Severe erosion has destroyed roads and caused losses of building in some regions while shoaling due to siltation in lake outlets and estuaries has resulted in navigation hazards and reductions in fish productivity. There has been considerable interest over the last two decades in the marked coastal changes observed along the Nile Delta Coast, leading to studies of; Coastal geomor• phology, analysis of beach profiles, aerial photography ana• lysis, satellite image analysis, shoreline changes and dynamic factors. Although nearshore bars are one of the most noticable features in the coastal environment, information and studies concerning the nearshore bars along the Nile Delta Coast of Egypt did not take the suitable attention.
