The study area comprises of thick overburden material. Cutting of slope for road construction activities on natural slopes and due over saturation of weak overburden material during incessant rainfall are the main causative factors for slope failure.

1. No heavy structures to be constructed near the crown area. 
2. Use of PVC pipes for drainage recommended for people living nearby.
3. 2-3 meter high retaining wall may be constructed with sufficient number of weep holes.
1. Extensive slope cut for road construction
2. Weak slope forming material
3. Saturation of weak overburden material due to continuous rainfall in the preceding days and development of local hydrostatic pressure in the weak slope forming material render
