A debris flow (sometimes called mudflow) is a flowing mixture of water-saturated debris that moves downslope under the force of gravity. Debris flows consists of material varying in size from clay to blocks several tens of meters in maximum dimension.

This computer simulation depicts the Sourgrass debris flow (Sierra Nevada, North Fork of the Stanislaus River), of January 1, 1997. The flow was 2.4 miles long, with a vertical drop of 2,000 feet. The first half moved 2 to 3 miles per hour, which is roughly the speed of a fast walk.

Wildfire-related Debris Flows USGS research on debris flows in burned areas focuses on determining the conditions and processes that cause debris flows and rapidly assessing the potential for debris flow in specific burned areas.

Wildfires can also lead to destructive debris-flow activity. In July 1994, a severe wildfire swept Storm King Mountain, west of Glenwood Springs, Colorado, denuding the slopes of vegetation. Discuss landslides and debris flow with your family. Everyone should know what to do in case all family members are not...
