The debris slide has occurred due to saturation of overburden (3.5 m) material by rainwater leading to increase in pore water pressure and reduction of shear strength causing failure

1. Trimming of crown scar. 2. Scaling of material at critical angle from slope surface. 3. Removal of loose unstable plants in crown portion. 4. Provision for hill side drainage.
1. Steep slope cut for road construction. 2. Saturation of thick overburden material (3.5 m) leading to the increase in pore water pressure and reduction of shear strength causing failure. 3.Rill erosion on the affected slope.
