Which risk elevates erosion behind barrier islands after storms?

💡 Explanation

Overwash transports sand across barrier islands, forming inlets and tidal channels; this results in intensified currents behind the island to erode those backshore areas because it increases tidal prism rather than reduces it, therefore tidal channel migration strengthens, rather than weakens stabilizing influences post-storm.
