- •
The present study assesses slope stability in three different scenarios.
- •
Stream head areas were identified as unstable zones in SHALSTAB.
- •
Vegetation root cohesion plays a significant role in slope stability.
- •
Probability of slope failure is a function of topography, soil and land use properties.
- •
SHALSTAB could explain up to 64.50% spatial variability of slope stability.
