Description :
A fifteen year history of coastal dune recession at Magillan, has revealed both time and space contrasts in processes and morphology. Since 1968 storm frequency has increased, while dune retreat reached a peak in 1978-1979. Three types of dune eroding events are noted, resulting from particular wave, wind, tide combinations. The spatial variability in dune scarping is associated with vegetation and soil development, and slope failures range from granular avalanches to retrogressive rotational slumps.
