Comprising of weathered sandstone, shale and carbonaceous shale, the study area is lithologically weak. Due to incessant rainfall for more than a week the pore water pressure increased and diminished the available shear strength of the thick overburden m

The weak lithology comprising of carbonaceous shale and sandstone of is causing a persistent problem to rail network along this section during monsoon period. The displaced mass was already cleared from the affected area during the time of investigation.

96 km, Migrendisa – Haflong rail section, near Diyung bridge.
1. Diversion of surface and sub-surface water away from the crown
2. Construction of lined drainage along the road 
3. Construction of retaining wall on sound sub-stratum at the toe of the slope 
4. Plantation of fibrous plants/grass on the affected slop
The affected area comprises of intercalation of carbonaceous shale and sandstone of Renji Formation. Cutting of toe of the slope for rail track construction in natural slopes constituting thick overburden destabilized the slope which on heavy precipitati
