Landsliding

Force balance at failure

Failure Conditions – The Effect of Water

Slope Failure – The Effect of Cohesion

What Processes Oversteepen Slopes?

Tectonic or Volcanic Tilting Downcutting (fluvial, glacial, etc.)

Slope Oversteepening Experiment: A Hill of Beans

Red Beans Experiments: Bean shape is more anisotropic (1.9cm x 0.8cm x 0.6cm)

White Beans Experiments: Bean shape is less anisotropic (1.0cm x 0.6cm x 0.5cm)
