Abstract
The sediment load carried by the Nile during the flood season, was the main source of forming the two promontories of Damietta and Rosetta. ween the sediment carried away from the shore and the sedi- ment supplied by the Nile seemed to favor accretion on the coast. This was the main reason to make the Rosetta Branch. of the river Nile to be protruded seaward. Since the erec- tion of the Aswan High Dam almost no sediment has been dis- charged from the NIle. This creats unstability and making the entire coast volnerable to severe erosion During the past, the balance bet Between 1898 and 1970 the Rosetta headland decreased in length by about Most of the energy driving the nearshore processes along the NIle delta coast comes from the Mediterranean Sea in the form of wind, waves and currents It seems that the dynamic interaction between the river Nile and the Mediterranean Sea has been affected by the con- struction of the High Aswan Dam in 1964 K.M The purpose of this survey is to obtain the hydrographic conditions, and the rate of errosion on the eastern side of Rosetta mouth during the different seasons.
