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

1. Scaling of material occurring at critical angle from slope surface. 2. Construction of retaining wall along the affected slope for toe support. 3. Provision for hill side drainage.
1. Toe cut of slope 2. SFM is composed of highly weathered and jointed country rock 3. Rainwater and freezing and thawing by snow causes saturation of overburden
