Document Summary
One of the biggest driving forces is the slope steeper the slope, the more likely there will be a landslide: depends on the types of materials on the slope and the climate. Many landslides happen especially in remote areas. When slopes are over steepened slopes are debuttressed for many landslides, it is the accumulation of water that creates water pressure which then can trigger the landslide. Classification of landslides regolith ( more common in usa) intensely weathered bedrock. We also classify landslides by the amount of water content whether it is dry or more wet. If completely loose and consolidated, it will not stand up steep. Great amount of water can decrease the cohesion. If there is clay, it will help hold the material together to stand up steeper. Debris flow is what often blocks highways. Earth flow, it flows like a decries flow but doesn"t flow as rapidly. Adding more water to material increase pore water pressure.
