On the Great Barrier Reef shelf, terrigenous sediments adjacent to the Herbert River delta are strongly partitioned within the coastal zone, in common with the regional presence of a terrigenous innershelf sediment wedge. Partitioning is primarily controlled by wind-driven currents and waves associated with persistent southeast trade winds. Bottom-return currents provide the likely mechanism for episodic transport of fine-grained sediment in an offshore direction, although modelled bottom-return currents appear incapable of transporting much sediment seawards beyond the 20 m isobath. This depth corresponds to the observed outer limit of the nearshore sediment wedge.
