Although along road level insitu rock is present, the road will not directly affect but the material from the higher level may slide down and block the road for that some gabion walls 1-2 rows can be given above the road which will arrest the sliding deb
Toe erosion by first order stream, improper drainage system and highly weathered rock. The highly jointed and weathered rock mass got saturated during heavy rain, resulted into decreasing shear strength and increasing pore water pressure.
