← GeographyWhich risk increases for settlements immediately behind artificial levees?
A)Increased localized flooding during levee breach✓
B)Diminished alluvial soil deposition rates
C)Higher frequency of channel avulsion events
D)More frequent coastal saltwater intrusion
💡 Explanation
The chance of localized flooding rises; because levees concentrate flow, a levee breach results in high water velocity and volume entering a focused area, therefore rapidly inundating the adjacent settlement rather than spreading as broadly across a floodplain.
