Which consequence results when a barrier island's overwash threshold is exceeded?

💡 Explanation

Increased estuarine salinity intrusion occurs because overwash transports seawater into normally freshwater areas; this process introduces excess NaCl via the mechanism of tidal forcing. Therefore, salinity increases, rather than decreased eutrophication, because nutrient deposition isn't necessarily reduced by the event.
