Abstract:This paper reviews the wave-beach-dune model of beach and dune interactions formulated by Hesp [1982] for micro-tidal beaches in eastern and southern Australia, and examines additions to, and more recent research principally on that model, but also briefly examines other models based on sediment supply variations. The model contends that dissipative beaches are characterized by high wave driven sediment supply, wide, low gradient beaches, maximum fetch, maximum aeolian sediment transport, largest foredunes and largest dunefields or dune systems, while reflective beaches are the opposite (minimal wave and wind driven sediment transport, narrow steep beaches, small foredunes and limited dunefield /dune system development. Intermediate beaches display a trend from high to low transport conditions, foredune size and dunefield development with a trend from dissipative to reflective. Future research ideas are also presented.
