Debris flow means a rapidly moving slurry of rock, soil, wood, and water, which is most often initiated by a landslide that delivers to and travels through steep, confined stream channels.
Debris flow means a slurry of rock, soil, organic material, and water transported in an extremely fast and destructive flow down channels and ontoand across alluvial fans; including a continuum of sedimentation events and processes such as debris flows, debris floods, mudflows, clear-water floods, and alluvial-fan flooding.
Debris flow means a stream-like flow of muddy water filled with mixed sizes of sediment and rock. Debris flows are generated by sporadic heavy rains on steep slopes.

I recommend that NSSL try to bring more focus to this area, rather than spreading its resources too thin by trying to do too many things (such as hydrologic modeling, Debris flow etc).

More Definitions of Debris flow
Debris flow means the rapidly downslope-moving mass of a viscous water- saturated mixture of rock fragments, soil, vegetation, and mud.
Debris flow means a moving mass of rock fragments, soil, and mud; more than half of the particles being larger than sand size; a general term that describes a mass movement of sediment mixed with water and air that flows readily on low slopes.
Debris flow means the rapid downslope movement descending steep pre-existing drainage channels of water-saturated soil and debris;
Debris flow means a moving mass of rock fragments, soil and mud, more than half of the particles being larger than sand size. Rapid debris flows can move up to 160 kilometers per hour.
Debris flow. OAR 629-600-0100 means a rapidly moving slurry of rock, soil, wood, and water, which is most often initiated by a landslide that delivers to and travels through steep, confined stream channels.
Debris flow means a moving mass of rock fragments, soil, and mud, more than half of the particles
Debris flow means levees consisting of coarse sediment up to large boulders in size with large accumulations of sediment and debris. They are the most powerful and destructive fan forming process, removing or altering entire stands or portions thereof. They are characterized by multiple active and inactive channels and gradients near the apex greater than 7% on average. Mature forest and deadfall within fans plays an important role in energy dissipation. Removal of mature forest from fans where this process dominates can result in events travelling farther downstream or beyond the feature where non-forest values can be affected, such as fish;
