Which condition causes accelerated barrier island erosion via overwash?

💡 Explanation

Reduced river sediment increases island erosion; wave OVERWASH transports sediment landward to the lagoon because there is less beach available to dissipate wave energy. This accelerates erosion rather than stabilizing the barrier; increased biodiversity or decreased land subsidence reduce relative coastal erosion.
