Due to the effect of toe erosion of a Nala that is flowing along the downslope of the road side and highly weathered overburden material, there is continued slope failure. Also reduced the cover leading to higher degree of percolation of rain water there

1. Crown portion should be eased and all hanging trees should be removed 2.Construction of toe supporting RCC wall with sufficient weep holes 3. Proper maintenance of hill side drains along road.
1. Unscientific hill slope modification for construction of road 2. Toe erosion by river 3.Highly weathered and jointed overburden material 4. Incessant rainfall resulted in reduction of strength on saturation and increase in pore water pressure
