15.3 What factors determine slope stability?

Fig 15.18

Cross sections to show types of slope stabiity.

Change of slope:

Both natural and artificial processes can alter slope. As streams (or construction) cut into a bank, slope is increased, thereby increasing the downslope forces.

Eventually the driving force becomes too great and failure occurs.
