These flows generally occur during periods of intense rainfall or rapid snow melt. They usually start on steep hillsides as shallow landslides that liquefy and accelerate to speeds that are typically about 10 miles per hour, but can exceed 35 miles per hour. The consistency of debris flows ranges from watery mud to thick, rocky mud that can carry large items such as boulders, trees, and cars.
Fluid movement of rock fragments supported by a muddy matrix- contains such material coarser than sand and tends to flow rapidly up to 100km/hr. Debris Avalanche. Fast downhill movement of soil and rock- speed results from high air or water contents and steep slopes- carries everything in its path. Slump. slow slide of unconsolidated material that travels as a unit. Slumps sit on basal surface that forms concave up shape- like spoon.
