← GeographyWhich risk increases within a levee-protected floodplain when upstream channel sinuosity creates frequent oxbow formations?
A)Increased groundwater recharge reduction
B)Levee overtopping at peak discharge✓
C)Accelerated floodplain soil salinization
D)Reduced sediment deposition on levees
💡 Explanation
Levee overtopping risk increases because increased sinuosity leads to higher peak discharge downstream due to lessened temporary storage by decreased stream length; increased flows overwhelm the limited levee capacity therefore threatening flooding rather than altered water movement.
