Which risk increases for settlements immediately behind artificial levees?

💡 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.
