Which outcome occurs when a barrier island's sediment budget shrinks?

💡 Explanation

Accelerated mainland erosion rates increase because reduced sediment supply weakens the island's capacity; therefore storm surge increases inland, rather than marine changes occurring due to sediment transport decline, via overwash.
