Abstract Benthic nearshore currents were measured continuously for a week over the subtidal zone fronting an open coast, macrotidal beach (spring tide range 9.5 meters) in Northwestern Australia. The shore-parallel currents were dominated by the semidiurnal tide; however pronounced asymmetries expressed the contributions of higher harmonics. Northerly flows at high tide were considerably stronger and of longer duration than southerly flows at low tide. Considering the combined effects of sediment agitation by waves and net transport by the tidal currents, it is shown that a mechanism may exist which could produce net northerly transport of “bed load” and southerly transport of suspended load.
