摘要

Coastal boulder deposits (CBD) found on rocky coasts are considered as the result of erosional and depositional processes by waves. These features are often attributed to extreme wave events such as major storms or tsunamis. Interest in their origin has increased considerably in the past 2 decades, especially after the 2004 and 2011 tsunamigenic events. This study attempts to review the literature available on this topic so far within the context of the Mediterranean region. This study shows how the main aims of research evolved from early descriptive works that tried to identify the causative source or event of boulder transport: storm or tsunami, to more specific evaluation of storm-induced transportation events and testing numerical models. Different methodologies used, as well as technological advances that facilitated data collection and observations, are also discussed. Finally, the study proposes future research directions to address gaps in knowledge relative to coastal erosion and identification of coastal hazards from flooding and inundation.
