← GeographyWhich outcome accelerates coastal dune migration during storm surges?
A)Increased aeolian sediment transport✓
B)Decreased vegetation stabilization
C)Enhanced swash zone deposition
D)Reduced groundwater table height
💡 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.
