Which consequence results when reduced sediment supply from rivers impacts longshore drift along a coastline?

💡 Explanation

Barrier island breaching probability increases because a reduction in sediment supply reduces the islands' resilience against wave action, meaning the deposition of sediments cannot keep pace with erosional forces from storm surges and tides via longshore drift; therefore, collapse is more likely rather than resistance to erosion.
