Abstract

The results of a study aimed at evaluating sedimentary and morphodynamic processes, induced by mainly marine weather events, on three gravelly-sand mainly siliciclastic beaches in Northeastern Sardinia are presented. Attention has focused on evaluating trends (progression, stability and retreat). In the last decade the Cala di Trana and La Sciumara beaches have shown a significative advance trend (between 3 and 8 m). The study was conducted testing and using the methodological standard of the European Project Interreg IIIA GERER, which allowed for the first time in Sardinia to employ high precision survey technologies and acquire seasonally data. This study, have enabled to understand the responses of the beaches in relation to different marine weather events occurring in the four seasons of repeated surveys and to define the dynamic of bars-troughs system by linking winds, waves, induced currents and sedimentology of the beach (dry beach and shoreface).
