Barreta Island
Description of Barreta Island
Barreta Island can be divided into two major sections: the western sector and the eastern sector. The western sector is dominated by the migration path of Ancão Inlet and frequently experiences overwash. The eastern sector has a recent history of shoreline progradation due to the construction of Faro–Olhão Inlet jetties (in 1929-1955) that interrupt longshore drift. The eastern sector of Barreta Island is one of EVREST project study sites as it presents a unique opportunity of studying beach ridge development, foredune development, dune vegetation evolution, amongst other processes.
