Which risk increases to barrier islands seaward when longshore sediment transport weakens?

💡 Explanation

Increased tidal inundation frequency rises because sediment starvation causes island narrowing via sediment transport. Without adequate sediment, overwash frequency accelerates because of the lack of a stable protective berm, therefore tidal inundation increases, rather than vegetation changes.
