Assessing the impact of climate change and sea level rise on the shoreline of Alexandria city – recreation area

Hany F. Abd-Elhamid, Martina Zeleňáková, Mohamed Mahdy


Coastal areas, the most attractive for a tourists, are becoming increasingly threatened by climate change and sea level rise (SLR) which led to increase the coastal erosion. Shoreline change is used in the detection of coastal erosion in coastal areas. The Digital Shoreline Analysis System (DSAS) with ArcGIS can be used in monitoring the shoreline change using a number of statistical measures including; Shoreline Change Envelope (SCE), Net Shoreline Movement (NSM), End Point Rate (EPR). This study aims to assess the impact of SLR due to climate change on Alexandria coasts. GIS and RS with DSAS were used in monitoring changes in the shoreline of Alexandria. The satellite images of 30 m resolution were used for the period (1985-2021) and geomatically corrected using Supervised Classification to determine the land uses and land cover changes. GIS was used for change detection, monitor changes in the land use and shoreline and predict the future changes in the shoreline for 10 and 20 years. The results showed that Alexandria shoreline has moved inland with different values along the coasts in the period (1985-2021) and the predictions showed more increase in 2031 and 2041. Results of this study could help policymakers to plan adaptation strategies to mitigate these impacts.
