← GeographyWhich risk increases along coastal barrier islands when inlets undergo rapid lateral migration?
A)Increased storm surge flood potential✓
B)Enhanced freshwater lens development
C)Reduced longshore sediment transport rate
D)Decreased marine biodiversity index
💡 Explanation
Increased storm surge flooding increases, because inlet migration widens breach areas, overcoming the protection provided by the pre-existing barrier. This is due to channel incision, therefore surge penetration increases, rather than a decrease caused by stabilized inlets.
