Abstract

Coastal erosion and sea level rise are pressing issues affecting coastal regions worldwide, posing significant risks to ecosystems, infrastructure, and human settlements. Traditional ground-based monitoring methods are often limited in scope and efficiency. Satellite remote sensing provides a robust alternative, offering comprehensive and high-resolution data on coastal changes. This article explores the application of satellite remote sensing technologies in monitoring coastal erosion and sea level rise. It highlights key satellites and methods used for shoreline mapping, change detection, sediment dynamics assessment, altimetry, gravimetry, and thermal infrared sensing. Case studies from the Mississippi Delta and the Maldives illustrate the practical benefits and critical insights gained from satellite data. Future directions point towards advancements in satellite technology and the integration of artificial intelligence, enhancing the predictive capabilities and accuracy of remote sensing for coastal management.
