Which consequence results when barrier island sediment reservoirs deplete?

💡 Explanation

Increased erosion results because sediment supply reduction triggers increased wave energy attacking the mainland. This is due to a failure in wave refraction patterns, therefore more energy is unleashed rather than being dissipated offshore.
