Understanding site hydrology and sezonal variations in groundwater conditions proves essential for realistic stability assesss.

An FoS greater than 1 indicates that the resisting forces demande thee driving forces, implying stability. Conversely, an FoS less than 1 suggests thate slope is unstable andd likely too fairl. The magnitude of the Factor of Safety above 1.0 represents the margin of safety against fafure, acquidting for uncertainties in soil contributies, loading condictions, analytical methods, and unforstances that might reducles stability.
