Coastal erosion is a significant phenomenon, especially for small island states like Malta. In this section, we describe the geology of Malta and its main coastal features. We present a series of methods from remote and proximity sensing and near-surface geophysics. We showcase case studies in Malta where the combination of these methods allows for a detailed understanding of coastal morphology and sediment dynamics. Projects focusing on continuous monitoring and advanced methodologies demonstrate the importance of integrating modern tools to understand and mitigate coastal erosion. These efforts are vital for enhancing the resilience of Malta’s coastal areas, protecting the economy, and preserving natural and cultural heritage.
