Final cover is a multilayered system of various materials which are primarily used to reduce the amount of storm water that will enter a landfill after closing.
The magnitudes of the tensile stress can be viewed as a function of the dimensions of the subsidence zone and the properties of the cover soil.
[2] Cover slope stability analysis involves evaluation of the interface strengths under static and seismic conditions.
Steepening of a slope past the design inclination increases the driving forces thus decreasing the Factor of Safety.
Decreasing the Factor of Safety past 1.0 could possibly push the final cover system components beyond their limits of stability.
