15.3 What factors determine slope stability?

Figure 15.20 shows debris flows on a burned hillside.

Fig 15.20

Vegetation:

Roots penetrate regolith and tend to bind particles together as well as absorb water. They are a stabilizing force on slopes.

Here we see the result of vegetative loss due to fire and the resultant mass movement.
