Coastal zones provide space for urban centers and a natural and cultural heritage that includes natural and human resources of ecological and strategic value. Like other seaside regions in the world, the coastal strip of Jeddah has been the scene of numerous urban and economic projects, where vast areas of marshes, shallows and coral reefs have been filled in, leading to radical changes at the land-water interface and at different depths. The aim of this research is to reveal the coastal changes in the study area and their impact on the environment (1965-2020). The methodology based on spatial analysis using Geographic Information Systems (GIS) of multi-source data, namely: Aerial photographs, 1951, 2009, satellite images Corona 1965, 1966, 1972, Landsat 1975, 2013, SPOT 1986, 2010, Sentinel 2018, 2020, maps of historic Jeddah in 1884 and field information. Digital Shoreline Analysis System (DSAS) software was used to estimate the rate of shoreline change, and vulnerability. The results of the research showed significant changes in the surface over the period adopted in the study, a change in the coastline by infilling in several places, and erosion in certain parts of the seafront. The study recommends the importance of giving priority to spatial planning and coastal development, and the integration between applied geomorphology and the components of environmental stability and balance, with the possibility of generalizing the study's methodology to other regions of Saudi Arabia.
