Which outcome develops when longshore drift overwhelms dune stabilization on a barrier island?

💡 Explanation

Island overwash occurs because sediment supply overwhelms the island's capacity to absorb it via aeolian transport and vegetation; therefore, the island migrates landward rather than remaining stable like atolls with balanced sediment budgets.
