Which outcome occurs when vegetation loss weakens levees?

💡 Explanation

Increased lateral channel migration will occur as the lack of vegetation leads to reduced soil cohesion allowing the river move laterally; this is caused by channel avulsion. Therefore riverbanks collapse because channel avulsion happens rather than floodplain robustness which requires stabilization by robust plants.
