Which process determines the rate of sediment deposition in an oxbow lake following channel avulsion?

💡 Explanation

When meander migration is cut off from the active channel, flow velocity decreases greatly in the oxbow lake because turbulence reduces and energy dissipation reduces, preventing coarser sediment to stay in solution. Therefore reduction of flow turbulence leads to rapid settling results, rather than alternatives which rely on compositional or biological mediation to form significant deposition.
