| description | This research studied the coastal changes along the region between Rosetta promontory to El Burullus fishing port with approximate length 58 km at Nile Delta Mediterranean coast, Egypt. Rosetta seawall was successfully built to protect the city from high erosion rate (-121 m/y), however erosion translocated eastward for 3 km with rate −64 m/y. So, a protection system of five groins was built eastward of the seawall. This has decreased the rate of erosion in the area to −45 m/y. After 2016, Ghalyon fish farm (GFF) manmade structures affected the balance of the coastline. So, a new groin protection system was built. This study aims to evaluate shoreline change pattern before and after the construction of GFF structures and to assess the gain and loss in land area. This was accomplished through the delineation of the shorelines from satellite imagery. The shoreline change statistics were calculated by the Digital Shoreline Analysis System software (DSAS). The research studied also the predicted shoreline and the impact of the GFF jetties’ lengths on the down drift side using 1-D model (LITPACK). The results revealed that by changing the length of the jetties, no notable change occurred in the eroded area. |
