← GeographyWhat height reduction occurs behind newly constructed artificial levees?
A)Enhanced overbank sedimentation✓
B)Decreased channel sinuosity
C)Increased sediment transport capacity
D)Diminished floodplain inundation
💡 Explanation
Enhanced overbank sedimentation occurs because channel confinement from the artificial levees reduces flow velocity at the levee's edge, causing increased sediment deposition closest to the water, therefore increasing deposit heights beyond the levee rather than more minor deposition farther away.
