Rainfall along with continuous freezing and throwing by snow, widens the joints and weakening of slope mas. and saturation by water causes increase in pore water pressure and reduction of shear strength causing failure

1. Trimming and removal of unstable plants in crown scar. 2. Scaling of protruding rock mass occurring at critical angle from slope surface. 3. Construction of retaining wall with sufficient weep holes for toe support.
1. Toe cut of slope for road construction. 2. SFM is composed of highly weathered and jointed peridotite intermixed with soil. 3. Rainwater, freezing and thawing by snow causes saturation of overburden leading to the increase in pore water pressure.
