Some 11,000 acres of intertidal land, up to half the tidal range including important feeding areas, may be lost.

The alternative, a tidal lagoon, would need an artificial lake in an area of shallow water with a high tidal range.

The morphology of the various types and sizes of barrier islands depend on the wave energy, tidal range, basement controls, and sea level trends.

Half tide docks are particularly useful in areas with a large tidal range.

As a result, extensive mud flats are deposited throughout the tidal range of the rivers.
