The Rosetta Promontory was created by sediment transported along the Nile River and delivered to the coast by the Rosetta branches. Following a long period of accretion, the promontory began to erode in the mid 1900s. This study deals with coastal processes, documenting the sediment transport rate and shoreline changes and predicting the future shoreline position along the Rosetta promontory. A mathematical model (actually made up of four separate models linked together) was deployed to study such processes where the Nile Delta meets the northern coast. The model is capable of calculating the wave characteristics, current distribution, sediment transport and the corresponding bed level changes. The main objective of this study is to install a station on the north coast of Egypt (at Rosetta) to estimate the amount of erosion and accretion and to have a better understanding of beach stability in view of existing structures. The present study documented the sediment transport rate and shoreline change and predicted the shoreline position along the Rosetta promontory by applying the numerical model "GENESIS" linked with three other models ("RMA2," "SED2D," and "NMLONG"). On the western side of Rosetta, the results of using the Longuet-Higgins, SPM formula and Gaven-Eagleson equations were in agreement with the measurements.
