Arretramento della linea di riva e rimozione della banquette di posidonia oceanica nella spiaggia di Peragan (Corsica meridionale)

The relationships between the removal of Posidonia oceanica ban­quette and shoreline retreat was analysed in the bay of Paragan, a pocket beach located in south Corsica. The morphological and sedi­mentological features of the beach have been compared with another pocket beach, the Pisciucani beach, located in the same sector, with similar characteristics. The results of the study showed that banquette removal in the beach of Paragan caused a retreat of the shoreline eval­uated in I 0-15 m, probably due to the variation of cross-shore beach profile toward more dissipative conditions
