The slope forming material is predominantly composed of thick overburden material comprising in-situ soil intermixed with rock fragments. Rainfall resulted in oversaturation of fragile overburden material, increase of pore water pressure and loss of cohe

1. Systematic channeling of drainages and disposal of surface water runoff. 2. Construction of gabion wall for toe support. 3. Proper maintenance of lined hillside drain.

1. SFM: thick in-situ soil with fragments of highly weathered rock mass (biotite gneiss). 2. Regolith/ overburden thickness of 2-5 m. 3. Hillslope dissected by drainages. 4. Active rill erosion on the affected slope. 5. Oversaturation of weak slope mater
