Which consequence results when migrating barrier islands breach?

💡 Explanation

Barrier island breaches cause rapid increases in tidal prism because scouring occurs. Tidal prism increase arises due to the newly created pathway between the ocean and the back-barrier lagoon, therefore increased prism volume, rather than wave behaviors or sediment dynamics, is the immediate effect.
