Tide-Dominated Estuary

A tide-dominated estuary consists of elongate sand bars and broad sand flats that pass headward into low-sinuosity channels; net sand transport is headward in these areas. The equivalent of the central basin consists of a zone of tight meanders where bedload transport by flood-tidal and river currents is equal in the long term, while the inner, river-dominated zone has a single, low-sinuosity (straight) channel.
