← GeographyWhich outcome results from channel avulsion in braided streams?
A)Increased floodplain sediment redistribution✓
B)Reduced aquifer recharge rates
C)Promoted hyporheic zone connectivity
D)Stabilized riparian vegetation communities
💡 Explanation
Increased floodplain sediment redistribution occurs because channel avulsion involves abrupt stream course changes due to sediment deposition exceeding transport capacity during high water events, a process known as base level rise; therefore, sediment spreads across new floodplain areas, rather than remaining within stable banks.
