Which outcome occurs when rapid sediment deposition obstructs alluvial channel flow?

💡 Explanation

Avulsion occurs because rapid sediment deposition overwhelms the channel capacity, invoking channel abandonment in favor of steeper pathways; therefore sediment redirects the water flow, rather than increasing capacity or decelerating oxbow formation.
