Which long-term outcome results from sediment disruption of tidal inlet hydrodynamics?

💡 Explanation

Barrier island migration toward the mainland occurs because increased sediment accumulation reduces tidal prism, reducing the cross-sectional area. Tidal asymmetry develops through Sediment Deposition. Therefore, islands migrate, rather than forming static sea stacks or involving plate tectonics.
