Which outcome results when barrier islands subside relative to sea level?

💡 Explanation

Submergence causes landward roll-over via marine transgression; Sediment Transport then moves sediments landward because coastal erosion removes the seaward sand face. Therefore barrier island segments shift back rather than increasing river sediment or altering incoming wave patterns.
