Shoreline Rotation Analysis of Embayed Beaches by Means of In Situ and Remote Surveys
The objective of the present study is to achieve a better understanding of the possible rotation of embayed beaches using shoreline position data from two beaches on the central Tyrrhenian Sea (Italy) during a 64-year period. With this aim, this study tests the utility of Differential Global Positio...
