Abstract

The Nile Delta of Egypt suffers from many coastal problems due to natural and human factors specially the eastern part from Damietta to Port Said. The aim of this paper is to investigate the coastal problems within the eastern part of the Nile Delta. This investigation depends on monitoring the frequency of change of the shoreline along Damietta Port Said shoreline. The Digital Shoreline Analysis System (DSAS) which is an extension for ARCGIS 10.5 was used to analyze shoreline change rates by using satellite images.  Six Landsat multi-temporal satellite images of years (2002, 2004, 2006, 2010, 2015 and 2020) were used to detect shoreline erosion and accretion patterns for the study area. These images were geometrically and radio-metrically rectified to be used in the analysis of shoreline change rates. DSAS tool with its three methods: End Point Rate (EPR), Linear Regression Rate (LRR), and Net Shoreline Movement (NSM) were used to identify the shoreline change rates. The results showed that the study area has faced many shoreline changes that differ between accretion and erosion. It is clear that coastal structures, human activities and the hydrodynamic forces are the main reasons of the shoreline changes within the study area.
