Description :
The aim of this paper is to describe annual changes of the sedimentary budget of 7 selected sites on the Ionian Islands and the western Peloponnese (Greece), which were determined by annual terrestrial laser scanning (TLS) during the years 2009 to 2011. A Riegl LMS-Z420 i laser scanner was used in combination with a DGPS. Moreover, TLS-based volume and mass data of dislocated boulders encountered at several sites were incorporated into tsunami wave transport equations and compared to buoy data. High-energy dislocated boulders showed no movement during the monitoring period. Thus, it is assumed that they were been transported inland by extreme events, which were stronger than the average coastal dynamics between 2009 and 2011. Both the orientation and the spatial distribution pattern of the dislocated boulders match with observations of boulders dislocated by tsunami impact.
