This chapter aimed at monitoring, analyzing, and quantifying shoreline dynamics along the Egyptian Mediterranean coastal strip from Sidi Abd El-Rahman to El-Arish over 3 decades (1987–2017) using remote sensing (RS) and geographical information system (GIS) technology, with special reference to Marina El-Alamein resort's shoreline. Besides developing predictive shoreline scenarios along Marina El-Alamein shoreline (for years 2023, 2057, and 2107). On-screen digitization technique was applied upon Landsat images (1987–2017) to detect areas of great erosion and accretion using ArcGIS 10.1. Incorporating DSAS 4.3 within ArcGIS facilitated quantification of shoreline changes and calculating erosion/accretion rates. Results generated shoreline change-maps for the entire strip for 30 years. Quantitatively, the entire coastal strip from Sidi Abd El-Rahman to El-Arish had dynamically changed over time. Constructing hard structures along Marina El-Alamein shoreline during the last 3 decades interrupted greatly the shoreline stability where seaward shifting was predominant. The overall trend of shoreline change rate indicated very high accretion with an average of 2.6 ± 4.64 m/year (EPR) and 2.54 ± 4.22 m/year (LRR). Shoreline evolution model predicted that the western inlet might be closed in the future. Consequently, careful planning coupled with long-term considerations is required when developing coastal engineering structures to ensure the sustainability of available natural resources.
