Which topographical feature forms down-slope following sediment deposition during episodic flooding cycles?

💡 Explanation

When fast flowing sediment-laden shifts from channelized transport, sediment gravity flow deceleration deposition occurs because confinement decreases, leading to build-up in layered distributions. Therefore alluvial fans are create, rather than other features which require different formation mechanisms.
