EDDY CURRENTS AND SEDIMENT TRANSPORT OFF THE DAMIETTA NILE

[摘要] Current meter observations indicate that a trapped eddy with a highspeed outer limb is formed downcurrent of the Damietta Nile promontory. This eddy is instrumental in the formation of the highly mobile sand body that extends seaward from the Damietta mouth, out onto the shelf, and curves back toward the coast just east of the Suez Canal entrance. Orientation of sand waves along the sand belt mirrors the direction of current flow within the eddy and indicates that the zone of reattachment of the separation streamline is located to the east of the Suez Canal. Dissipation of this sand belt will likely result in increased coastal erosion locally.
