← GeographyWhich process increases flood severity downstream during levee construction?
A)Accelerated channel sediment carrying capacity efficiency
B)Reduced floodplain water storage capacity✓
C)Decreased regional groundwater recharge potential
D)Increased evapotranspiration rates locally inland
💡 Explanation
Restricting a river by levees prevents natural floodplain inundation; this increases water volume downstream because floodplain storage vanishes, therefore boosting flood peaks rather than mitigating discharge in a widespread fashion.
