Coastal erosion is a significant environmental and socio-economic issue that has affected shorelines globally since the mid-19th century. Shoreline degradation and instability threaten property, businesses, and human life, requiring effective marine governance and engineering interventions. Understanding coastal change is essential for the efficient monitoring and management of the coastal areas, mitigating the impacts related to the shoreline retreat. This thesis focuses on the coastline of Follonica, located in the Gulf of Follonica (Tuscany, Italy), following its evolution from 1973 to 2023 and predicting the future scenario up to 2040. Aerial images provided by Regione Toscana and from Google Earth Pro have been analysed to evaluate historical erosive and sedimentation trends, considering the different anthropic structures built along the coast over time.
