Which effect on polar rivers results from increasing near-shore permafrost thaw?

💡 Explanation

Increased thaw causes more surface runoff and erosion, therefore leading to increased stream discharge and sediment load because the active layer is not frozen. Mass wasting of banks rather than sediment trapping characterizes thermal erosion, rather than stabilization or reduced meandering.
