Which flooding consequence occurs when an alluvial fan's sediment transport pathway becomes overloaded?

💡 Explanation

When an alluvial fan is overloaded, aggradation causes the slope to become unstable and increases channel sinuosity because increasing bedload prompts channel instability. Therefore, avulsion results which causes a relocation of the flow path, rather than oxbow formation, enhanced infiltration or downcutting, which are related to different fluvial processes.
