ABSTRACT
Coastal areas, vital for local communities, are subject to significant changes requiring rigorous management. This study focuses on assessing the evolution of the Atlantic coastline between Larache and Moulay Bousselham over a period of 60 years, with an emphasis on erosion and accretion risks. The main objective is to understand coastal change trends and identify the most vulnerable areas. Using advanced techniques such as multi-temporal photo interpretation, Geographic Information System (GIS), and the Digital Shoreline Analysis System (DSAS), we analyzed aerial and satellite images from 1963, 1991, 2014, and 2023. The results reveal that zones A (Msitro Beach) and B (Lhayayda Beach) are primarily affected by erosion, with minimal accretion, while zones C (Mersat lghnem beach) and D (Moulay Bousselham Beach) exhibit more intense erosion. This study provides an original contribution by combining advanced analytical methods to inform the sustainable management of coastal resources. Keywords: Atlantic coastline, erosion, accretion, DSAS, GIS.
