Abstract
Coastal Engineering is the branch of civil engineering concerned with planning, design, construction, and maintenance of works in the coastal zone. Coastal engineering usually involves either the transport and stabilization of sand and other coastal sediments or the construction of structures. Coastal engineering plays an important role in both developing the coastal zone and protecting the coast and the hinterland. For doing that coastal engineering needs a thorough knowledge of the natural dynamic of the coastal system. Coastal erosion is a global problem. Coastal protection may be ensured through natural or man-made systems, or a combination of both. The coastal zone suffers from sedimentation, accretion, and pollution problem as well as the side effect of climate change which increase beside sea level rise and storm surge. A major effort has been doing to manage the coastal erosion problems. These problems facing numerous types of hard structures. The coastal engineering thinks about new techniques to deal with the erosion problems with environmentally friendly structures by taking into consideration the effect of all factors which controlling the process. Due to large subsidence in the Nile Delta region, Egypt is considered one of the top five countries expected to be most impacted with a 1 m sea level resulting from global warming. Egypt`s natural resources such as coastal zone and water resources may be subjected to vulnerability. Generally, in Egypt applying hard defenses proved to be unsuccessful. The traditional ways of protection on the Egyptian coast have side effects on the environment and beach morphology. Many coastal problems can be solved by reach the natural situation before the building of the Aswan high dam. Because the stop of sediments and flow create a disrupted situation represented in severe erosion, water degradation.
