Which outcome is directly mitigated by building levees along alluvial plains?

💡 Explanation

Levees increase the channel's water capacity, therefore reducing flow onto the alluvial plain; this is because the mechanism is channel confinement. Levees primarily affect flow frequency rather than infiltration or sediment concentration changes.
