Which hazard increases near the down-sloping head of an alluvial fan?

💡 Explanation

Increased slope from topography steepness commonly triggers 'channel avulsion,' because sediment accumulates unevenly, therefore causing the channel to seek a steeper path rather than maintaining its current flow, rather than changing weathering or deposition alone.
