Abstract

Shoreline erosion has been a major problem in the Nile Delta since the full damming of the Nile River in 1970, especially along the two Nile promontories (Rosetta and Damietta). Since that construction of the Aswan High Dam in 1964, there has been concern that the Egyptian coastline

along the Mediterranean Sea would suffer from increased erosion. The dam effectively stopped the supply of sediment carried by the River Nile to the Mediterranean and so left the coastline without shore building capability. The main goal of this study is to assess the coastal hazards that may occurred due to shoreline changes (erosion or / and deposition). Through analysis of four satellite images from the multi-spectral scanner (MSS), thematic mapper (TM), The Enhanced Thematic Map < /span>per Plus (ETM+) sensors and the Modis sensor were utilized in order to estimate the spatio-temporal changes that occurred in the shoreline between Damietta Nile branch änd Port-Said between 1975 and 2011.Image processing applied in this study included geometric rectification; atmospheric correction; and filtering processes on-screen shoreline digitizing of the four satellite images for tracking the shoreline position between Damietta promontory and Port Said. Results showed that shoreline between Damietta and Port Said is characterized by appreciable erosion and accretion the coastal erosion was severe near Damietta promontory and decreased eastward, while accretion was observed near Port-Said
