Which outcome occurs when sediment supply fluctuates heavily in an alluvial fan system fed by glaciofluvial till?

💡 Explanation

Increased sediment fluctuations will overload transport capacity. This increases the frequency of avulsion (channel jumping) by Stream Piracy because channels seek steeper, more efficient routes. Therefore, avulsion rates increase downstream, rather than stability or simple migration under steady flows.
