Abstract
The dangerous effect of the wind waves on the Nile Delta coast took the attention of the researchers for many decades. The worst effects can be classified as erosion effect, along the coast the sedimentation effect at the outlets of the estuaries and lakes, and drowning of some lands during the storms.
For thousands of years the sediments came with the Nile flood causing some balance against the erosion. The effect of waves was stronger and caused erosion at certain sites like Rosetta and Damietta.
Since the construction of the Aswan High Dam south of Egypt all sediment materials settled upstream the dam and do not reach anymore to the Delta coast. To save guard the coastal area against scour and erosion many structures have been erected like breakwaters, groins, seawalls and nourishment according to the nature of the area. All the protection projects were decided according to the collected field data for many years.
During some seasons severe storms occurred causing high wave runup and drowning of some coastal lands. This problem took the attention of the writer especially after the strong storm in 2010 which attacked the coastal area causing damage of many beaches of Alexandria. The same case happened at many other places along the coast e.g. at Burullus area. It became very necessary to study the problem and prepare a soft model to suite the Egyptian coasts during all seasons. As the storms takes very short time, and its effect is immediately and decision maker needs a quick data, so it is necessary to prepare a computer program to suit this point.
Model (DINA-RUNUP) is developed to calculate the wave runup at any time for any storm and at any site along the coast of the Delta .Using the still water level plus tide not including wave setup and the Egyptian metrology (Wind –fetch-Wave conditions) as input. Estimation of the max,mean and average runup wave compared with the land level on each profile is the output.
The Study area is coast area of the Nile Delta at the north of Egypt. It extends from Rosetta branch to Damietta branch with total length of 190 km. This area is typically a smooth wide coast with different natural features including wetlands, elevated coastal sand dunes, empty narrow strips of land slightly higher than sea level and brackish lakes connected to the Mediterranean Sea.
The Study shows the dangerous coastal zones areas at the Nile Delta Coast which might be affected by the wave runup and overtopping.
