Construction of retaining wall with weep holes and lined toe drainage, easing of the slope, removal of unstable debris material from slide zone
Increase in the pore water pressure and decrease in shear strength of the overburden material due to heavy rainfall. Removal of lateral support of the slope due to steep cutting for construction of road has reduced the stability of the slope, making it m
