← GeographyWhich flooding outcome occurs when frequent deposition overloads fans at mountain fronts?
A)Increased avulsion channel migration✓
B)Stabilized floodplain soil cohesiveness
C)Decreased groundwater table recharge
D)Diminished levee construction effectiveness
💡 Explanation
Increased avulsion and channel migration happen because of aggradation via the channel overloading mechanism at the apex, therefore channels seek steeper pathways, rather than floodplain stabilization which would require decreased sediment load.
