The shallow rotational debris slide has occurred due to slope modification. During rain fall, prolonged infiltration of water along the slope surface, developed a local hydrostatic pressure its leads to the reduction in shear strength.

1.Clearing of weathered and unstable material from the slope face. 2.Hillside lined ditches may be constructed and maintained regularly to prevent runoff infiltration. 3. Reducing the general slope angle by slope dressing may be considered.
The slope modification initiated by road construction and the prolonged percolation of water developed a local hydrostatic pressure on the overburden material and its leads to the reduction in shear strength.
