This paper presents a semi-empirical model for describing sediment dispersal on the central New South Wales (N.S.W.) continental shelf. Results from a program of field experiments identify wind speed and direction, wave height and frequency distribution of near-bottom currents as being the dominant factors influencing near-bottom current asymmetry on this shelf. A combination of theoretical prediction and field experiment has been used to define the seaward limits for onshore/offshore sediment exchange and the modes of sediment transport operating within this active zone.
