Development of coastal Holocene transgressive dunefields: Examples from South Australia

Research output: Contribution to conferencePaperpeer-review


The development of coastal transgressive dunefields has been the subject of numerous studies internationally. The extent and volume of dunefield development has been frequently attributed to sediment supply and exposure to onshore/alongshore winds above the threshold to initiate sediment transport. In South Australia, where terrigenous sediment supply is very limited, the nearshore is an important source of carbonate sediments to Holocene barriers to a degree proportional to the wave energy. Here we test the wind and wave control in dunefield development in a variety of environmental settings across South Australia. Wind data (observed and from reanalysis products) and dunefield dimensions have been analyzed along the South Australian coast, and demonstrate that aeolian drift potential is an important control in areas where wave-driven sediment delivery is limited; however, it does not fully explain dunefield development in wave-exposed areas.
