The prolonged infiltration of rainwater along the unconsolidated overburden material leads to the increased pore water pressure and resulted in failure along the slope.

1. Provision of hill side road drainage. 2. Removal of loose material occurring at critical angle and unstable uprooted plantation from slope surface. 3. Construction of retaining wall for toe support.
1. Weak overburden material comprises of rock fragments of parent rock intermixed with soil. 2. Loss of cohesion and saturation of overburden resulting in increase of pore pressure during rainfall. 3. Rill erosion on the affected slope.
