Question

Quizplus · Accepted Answer

Debris flows are high-energy events that occur when sediment and debris mix with water and rapidly flow downhill. As they exit a narrow canyon, the debris flow loses velocity and deposition occurs, resulting in the creation of an alluvial fan. Alluvial fans are fan-shaped deposits of sediment that accumulate at the base of a mountain range or canyon.
