The debris slide triggered due to adverse condition of slope forming during heavy rainfall slope forming material gets oversaturated leading to increase in pore water pressure and loss of cohesion.

1. Removal of slided material along with plants from road and retaining wall. 2. Trimming of crown scar. 3. Repairing of collapsed and damaged retaining wall. 4. Construction of lined drainage along the toe of the slide.
1. SFM is composed of loose unconsolidated rock fragments intermixed with soil. 2. Toe cutting of hill slope for road construction. 3. Saturation of SMF during rainfall leading to pore pressure and loss of cohesion.
