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.

• Following a river avulsion event, which process promotes oxbow lake formation when the river establishes a straighter course?
• Which outcome occurs when vegetation removal precedes loess deposition?
• Which mechanism initiates desert pavement formation within an alluvial fan environment?
• Which outcome commonly results where oceanic transform faults terminate near subduction zones?
• Which mechanism causes increased anchovy populations following strong coastal upwelling events?
• Which risk increases when upstream river engineering projects disrupt sediment deposition in floodplains adjacent to engineered levees?
