Which outcome increases with excessive levee construction along a fluvial system?

💡 Explanation

Increased levee height restricts the floodplain's water capacity, therefore increasing downstream flood intensity is guaranteed by channelization, rather than decreased intensity, because the water isn't able to undergo natural attenuation. This process occurs by increasing river channel conveyance.
