Which outcome occurs with increased land subsidence near a barrier island?

💡 Explanation

Land subsidence lowers the overall elevation making the barrier island more vulnerable; increased wave overtopping therefore occurs because the crest elevations are lessened allowing more wave energy to pass over the island, rather than being blocked as during normal conditions.
