The study area is lithologically weak which 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 f

1. Moderation of upslope by construction of intermittent benches.
2. Construction of retaining wall at the toe portion of the slope with sufficient weep holes may be considered.
3. Construction of drainage ditches along the road.
Excavation or cutting of toe for road construction activities on natural slopes disturbed the angle of repose of the material, and heavy downpour resulted in over-saturation of slope forming material which in turn increased pore water pressure and reduce
