The debris slide occurred due to planer failure. overburden soil is unstable along the extensive slope cut in steep sloping topography during rainfall

1. Removal of slided debris material on the road side. 2. Trimming of crown scar along its length 3. Providing hill side lined drain.
Pore pressure developed in the unconsolidated slope forming material during heavy rainfall reduces its shear strength and leading to slope failure on gravity.
