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 and proper maintenance of lined hillside drain.
1. SFM: thick in-situ soil intermixed with fragments of rock underlain by weathered gneiss. 2. Regolith/ overburden thickness of 2-5 m. 3. Overburden failure along the rock and overburden interface. 4. Hillslope dissected by drainages. 5. Active rill ero
