Which outcome accelerates coastal dune migration during storm surges?

💡 Explanation

Increased hydraulic flow at the base destabilize the lower dune surfaces because hydraulic sorting decreases grain sizes, causing increased aeolian sediment transport; therefore, dunes migrate faster inland rather than experiencing reduced sediment available with vegetation stabilization present alone.
