The debris slide has occurred due to toe cutting of hill slope cut for road construction. Rainwater causes saturation of overburden (2.5 m) material leading to the increase in pore water pressure and reduction of shear strength causing failure.

1. Repairing of retaining wall and removal of slided material to avoid blockage of weep holes. 2. Removal of slided material from road and slope surface. 3. Plantation of bamboo, vetiver on slope surface to prevent erosion.
1. Toe cutting of hill slope.  3. Minor drainage dissection on the affected slope. 3. Oversaturation of thick overburden material (2.5 m), causes saturation of overburden leading to the increase in pore water pressure.
