Inlets with large tidal prisms can erode sand and deposit it in ebb-tidal deltas in deeper waters (National Research Council). The size of ebb tidal deltas is proportional to tidal prism. If tidal prism increases, there is an increase in deltas and shoals formed by sand transport during ebb tide. There are assumptions that go along with tidal prism models. The first is that they are applied to smaller estuaries (less than a few
