The origin of foredunes and sandy beach ridges

Authors(s) and Affiliation(s)

BIRD E. C. F. ;


Studies of prograded sectors of sandy coastline in Victoria have shown that some are initiated upon wave-built beach berms colonised by dune vegetation that begins to trap wind blown sand| others develop where backshore terraces built under dune vegetation spreading from pre-existing dunes are trimmed back by storm wave erosion, forming a dune cliff capped by spillover sand which becomes a foredune as further aeolian accretion proceeds. A berm is defined as an impersistant wave-built ridge or terrace on the beach face| a beach ridge is a more persistent wave-built ridge formed at or above high spring tide on a prograding sandy coast| a foredune is a ridge of aeolian sand running parallel to the coastline.
