Analysis of the Rockfall Phenomena Contributing to the Evolution of a Pocket Beach Area Using Traditional and Remotely Acquired Data (Lo Zingaro Nature Reserve, Southern Italy)

The coastal domain of central western Sicily is characterized by the presence rocky coasts, which mainly consist pocket beaches situated between bedrock headlands that constitute ecological niches great touristic and economic value. In this peculiar morphodynamic system, sedimentary contributions are derived from rockfall affects back nearby cliffs or sediment supply small streams flow into it. study, we investigated geomorphological processes related landforms contribute to evolution a beach area located in sector NW Island. affected several rockfalls, deposits these rockfalls also add rate contribution. analysis was conducted through application traditional approaches contemporary methods have previously been used forecast collection input data field, often under difficult conditions due accessibility sites, supported UAV surveys. Through digital models terrain orthophotos, geometrical multitemporal analyses were carried out. A dedicated software utilized for detection runout zones block trajectories defining automatic extraction rock mass discontinuities. compared with those geomechanical availability existing acquired remote sensing proved essential study both reference geological model performing site-specific rockfall.
