Document Summary

Describe how the impact of landslides depends on: population density, economic infrastructure, & population preparedness. We want to own property that doesn"t get destroyed (26609$ economy & rebuilding) Explain why bc has the highest frequency of landslides in canada & what we should expect as our population expands into the mountains. Bc has more mountains than the other provinces. As our population expands into the mountains, we should expect more landslides. In the southern canadian cordillera (southern bc): return period = 25-70 yrs. Seasonal heavy rains fall on steep slopes covered by loose sediments. Distinguish between the 3 main failure models (falls, flows, & slides) and how they are influenced by geology. Material moves as a coherent mass along a surface of failure (either curved/straight) Cohesive motion of material along a flat surface. Categorize, identify, & name a variety of landslides. Cohesive block moves on a failure surface.
