GG231 Lecture Notes - Lecture 5: Tiltmeter, Debris Flow, Slope Stability
Document Summary
Moves through air and lands at base of slope. Dry process triggered by vibration, human/natural wedging (ice or vegetation) Rapid process hazard for those underneath: slide. Movement in contact with underlying surface - along a plane surface. Identified by: character of surface of plane, type of material (rock, sediment), water content, speed of movement i. e. rockslide, translational slide slump, slip: flow. Plastic or liquid movement, in water or air. Mass breaks up and flows during movement. Forces on slope: 6 factors that impact the ratio of driving and resisting forces: Human processes: urbanization, transportation corridors, and natural resource use, timber harvesting, urbanization i. e. rio, mining, aberfan wales 1966, utah, us. It triggered a quake rather than the other way around. No one was hurt or killed, lower than. Natural processes landslides: new surface for plant growth, new habitat for plans and animals, regional biodiversity, create minerals.
