The shallow rotational debris slide occurred due increase pore water pressure in slope forming material during heavy rainfall. This reduced the shear strength of SFM and thus initiated slope failure.

1. Construction of toe support retaining wall with sufficient weep holes 2.  Construction of lined hill side drainage with proper gradient along the affected road section.
Developed pore water pressure in the slope forming material due to oversaturation during heavy rainfall thereby, reduces the shear strength of SFM.
