Document Summary

The classification system is based on the type of material, type of movement and amount of speed involved(to a lesser degree) Earth is wet and saturated common in b. c with silt and lake sediment: debris flow(referred to as mudflow by the media) is much more common mix of boulders sand silt and clay. Debris avalanche not as fluid as a debris flow: these are common in alpine areas. Much of vancouver is affected by permafrost (occurs in alpine areas : this is how you get solifluction. Complex-- meaning several different types of movement associated with the landslide: falling, avalanche and debris flow all happening in one landslide. Bedrock where there are fractures and inclined up into the slope (daylighting) If driving forces are greater than the resistance forces this can cause a landslide: resistance forces: cohesion. **slopes have a strong influence on whether or not we get landslides.
