Which outcome results when levee erosion in an alluvial plain?

💡 Explanation

Avulsion happens because levees confine river flow; reduced confinement due to erosion results in a breakout. The river adopts a steeper path, therefore forming a new channel across the floodplain, rather than maintaining the original path.
