Which hazard increase results when levees constrict flow?

💡 Explanation

Lahar inundation severity escalates due to increased volume and velocity within the channel because levees prevent natural spreading and deposition; therefore lahar flows concentrate into more erosive and powerful currents rather than other types of flows.
