The slope material consist of thick section of loose in-situ soil and fragmented sandstone and due to incessant rainfall for about a week, overburden got over saturated and developed local hydrostatic pressure which diminished the available shear strengt

Slope is vulnerable to further degradation , hence early mitigation measures are to be implemented. Landslide occurrence on 22nd May, 2016
Haflong – Gunjung road section slide-08
Near  Gunjung village road section
1. Construction of retaining wall at the toe portion of the slope with sufficient weep holes founded on hard sub-stratum.
2. Construction of  hill side lined drains/ ditches along the road 
3.  Easing of the slope by benching.
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 reduced its shear st
