Steel Rebar. Reinforcing bar, or rebar, is a common steel bar that is hot rolled and is used widely in the construction industry, especially for concrete reinforcement.
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.
Director of the Forest Service Utah Avalanche Center (Much of this material is reprinted from the Book Staying Alive in Avalanche Terrain by Bruce Tremper and published by Mountaineers Books, 2001.) How fast do avalanches go? Dry slab avalanches typically travel 60-80 miles per hour. They reach these speeds within about 5 seconds after they fracture. Wet avalanches usually travel much slower, around 20 miles per hour. What kind of avalanche is most dangerous? Dry slab avalanches account for almost all avalanche fatalities. A slab avalanche is like a dinner plate sliding off the table. A cohesive plate of snow slides as a unit on top of weaker snow. The slab shatters like a pane of glass with the victim in the middle of the slab and usually there's no escape.
