Which shoreline outcome increases when sediment supply decreases?

💡 Explanation

Barrier island migration inland increases because washover processes dominate land-building; therefore, decreased sediment supply leads to this outcome, rather than the other options which require a surplus of materials for creation and stability. The primary mechanism is sediment transport.
