ABSTRACT : Remote sensing technologies have revolutionized the way coastal erosion and sediment transport are monitored, providing spatially extensive, temporally frequent, and cost-effective data. Coastal zones are dynamic interfaces where land, ocean, and atmosphere interact, leading to complex processes of erosion and sediment deposition. Traditional in-situ monitoring methods, though accurate, often lack the temporal and spatial coverage required for comprehensive coastal management. The integration of multispectral, hyperspectral, LiDAR, and Synthetic Aperture Radar (SAR) techniques, coupled with Geographic Information Systems (GIS), enables the generation of accurate shoreline change maps, sediment transport models, and erosion susceptibility assessments. This paper presents an in-depth review of remote sensing methodologies for coastal monitoring, their applications, limitations, and future prospects.
