The affected site is lithologically weak comprising of weathered sandstone, shale and carbonaceous shale of Renji Formation. The slope failure occurred on colluvial foot-slope. Colluvium materials are loosely packed and on saturation during heavy rainfal

New Haflong R. S slide(1)
West slope of New Haflong Railway Station.
1. Height of the retaining wall may be increased upto 5 m above the toe.
2. Moderation of upslope after the construction of retaining wall by two tier benching.
3. Training of surface drainage by proper drainage arrangements away from the displaced mass.
The slide occurred due to combination of several factors:
1. The major geological causes are presence of weathered rock and loose material, development of pore pressure and reduction of shear strength of the material due to saturation by water percolatio
