Which outcome is most likely when artificial levees collapse along a major river?

💡 Explanation

Widespread floodplain inundation occurs because the levee no longer prevents floodwaters from spreading onto the adjacent land; this is due to Hydraulic breach exceeding capacity, therefore water flow overwhelms the original designed protection capability rather than sediment changes elsewhere.
