← GeographyWhich outcome occurs when deforestation removes vegetation alongside levees?
A)Increased rates of levee undercutting✓
B)Decreased sediment deposition on levees
C)Enhanced levee soil permeability
D)Reduced risk of levee collapse
💡 Explanation
Deforestation near levees accelerates erosion initiating levee undercutting because removal of root systems exposes soil to direct fluvial action. Streambed incision occurs therefore basal erosion increases, rather than protection against it from vegetation.
