Which risk increases when deforestation significantly reduces levees' vegetation cover?

💡 Explanation

When deforestation reduces vegetation cover, soil destabilization from root loss leads to increased erosion and reduced levee structural integrity because the root systems that bind the sediment weaken. Therefore levee failure during floods becomes more likely, rather than deposition increases, enhanced recharge, or reduced migration, which contradict the effect of destabilization.
