Which outcome results when channel avulsion breaches a levee?

💡 Explanation

Avulsion introduces a large sediment load onto the floodplain because the breach creates a new, often shorter, flow path with high sediment transport capacity causing rapid deposition, therefore sedimentation greatly increases rather than salinity or laminar flow due increased sediment load.
