The present study represents an attempt to classify and evaluate the surface water quality around Ras El-Bar Island by investigating the surface water physical and chemical parameters near Damietta Branch Outlet, Damietta Port Canal and Mediterranean Sea. The measured pH values show a tendency towards alkaline side aquatic system. The variations in the total dissolved solids and the electrical conductivity values show relatively high values in the Sea water compared with that in the Damietta Branch and the Damietta Port Canal. The observed increasing in the dissolved solids and electrical conductivity values seaward may be related to the effect of sea water intrusion. However, the observed lower values of the dissolved solids and electrical conductivity in Damietta Branch water may be related to the effect of receiving many waste-water resulted from domestic sewage, industrial activities and the extensive boating activities at Ezbt El-borg. The sodium and chloride values increase downward, through Damietta Branch toward its outlet to the Sea water and through the site of connection with the Damietta Port Canal toward the sea. The observed increasing in sodium and chloride values seaward may be related to the effect of sea water intrusion.The potassium, calcium and bicarbonate values decrease downward, through Damietta Branch toward its outlet to the sea water and through the site of connection with the Damietta Port Canal toward the sea. The observed decreasing in Potassium, Calcium and Bicarbonate values seaward may be related to the effect of sea water intrusion. The alkalis (Sodium and potassium) exceed alkaline earths (calcium and magnesium) and strong acids (Cl+SO4) exceed weak acids (C03+HCO3) indicating secondary salinity. High contents of Lead and Cadmium values are observed in the in the study surface water around Ras El-Bar Island. Cadmium and Lead fall in the category "high". The category "high" is usually observed near the main shipping routes to the ports.The studied surface water samples show non-permissible water quality for drinking, domestic and irrigation purposes.

Rosetta promontory encompasses both the east and west sides of the Rosetta River mouth branch. Since the building of the High Dam in 1964, the Rosetta promontory has been subjected to dramatic erosion. Two concrete seawalls have been constructed on the shoreline to protect the river mouth at Rosetta promontory from the prolonged sea invasion. Moreover, four groins were constructed to minimize the shore erosion and stabilize the eastern margin of the promontory. Also, many groins were constructed to stabilize its western side but they were destroyed. The present study deals with the effect of wind generated waves on the beach configuration. It also determines the equilibrium orientations of the shoreline and the effective protective constructions. Monthly wind generated waves along Rosetta area are determined and graphically presented. The sea state, the wave parameters, the resultant equilibrium orientation of Rosetta promontory beaches are determined. The suitable months for constructing the recommended protective constructions along Rosetta promontory are nominated. Moreover, the distribution of the beach face sediments, their grain size and their heavy minerals content around Rosetta promontory are thoroughly studied. Finally, recommendations for the protection of Rosetta promontory are given.
