← GeographyWhich outcome occurs when a hydraulic structure alters sediment transportation near barrier islands?
A)Increased sediment deposition downdrift ensues
B)Landward island migration would be prevented✓
C)Longshore drift pattern remains constant
D)Overall marshland is permanently expanded
💡 Explanation
Interruption of sediment supply restricts island rollover; this stabilization occurs because construction blocks the natural *sediment budget* from overwash. Therefore, the island's landward migration is often prevented rather than allowing natural adjustment based on sea level changes.
