Which erosional consequence results when fan sediment supply diminishes?

💡 Explanation

Incised channels strengthen when less sediment is deposited because fluvial systems begin to downcut through the existing deposits to maintain equilibrium by a process called base-level adjustment; therefore incised stream formation strengthens, rather than braiding, stabilized bank erosion or wide flooding events.
