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.
1 Landslides occur when masses of rock, earth, or debris move down a slope. 2  They may be very small or very large, and can move at slow to very high speeds. 3  However slow movement is also seen in the gradual downhill creep of soil on gently sloping land.actors that affect mass movements are the steepness and instability of slopes, the nature of the slope materials, and the amount of water in material. Types of mass wasting: 1  Rate of Movement-rapid or slow. 2  Type of Movement-falling, sliding or flowing.
