Formula & Methodology
The calculation uses the following formula:
F = c * H + (γ * H² * sin(α) * cos(α)) / (2 * cos³(α))
Where:
- F = Factor of Safety
- c = Cohesion
- H = Height
- γ = Soil Density
- α = Slope Angle

What is the Factor of Safety?
The Factor of Safety (FOS) is a measure of the stability of a slope. A FOS of 1 indicates marginal stability, while a higher FOS indicates greater stability.
