Characteristics of morphodynamically reflective, intermediate, and dissipative beach systems, from the data of Short (1984), are used with an iterative aeolian sediment transport model to predict beach-state controls on transport rates. The predictions are based on the transport model of White (1979), the moisture effect model of Belly (1964), and the slope-effect model of Hardisty and Whitehouse (1988). The model adjusts profile geometry continuously as sand is preferentially eroded and deposited across the model beaches. For an assumed shear velocity of 0.50 ms-1, sediment transport rates were about 20% larger for the dissipative system compared to the reflective beach. For a shear velocity of 0.75 ms-1, about 80% more sand is removed from the dissipative beach. These results suggest that the Short and Hesp (1982) conceptual model of beach state-dune form relationships is valid and can be quantified.
