Which risk increases when extensive vegetation removal occurs on river levees?

💡 Explanation

When vegetation is removed, the mechanical stabilization provided by root systems is eliminated, increasing soil erosion because soil is no longer bound, reducing slope stability. Therefore localized levee collapse risk increases, rather than overtopping, migration, or sediment deposition which require specific hydraulic conditions and basin morphology.
