Which risk increases when reduced sediment supply hinders sand deposition behind a developing coastal barrier island?

💡 Explanation

Increased storm surge overwash occurs due to barrier island degradation. Sea level rise causes shoreline retreat through marine transgression, rather than isostatic rebound. Storm surge overwash results because impeded sediment transport hinders natural island building processes.
