Oversaturation of slope forming material and increase in local pore water pressure during heavy rainfall results in failure of the slope forming material along weak plane (Bedding plane).

The NH54 in this hill section passes through highly dissected hill slope and escarpment. It is observed that the road side drains are poorly maintained and no slope protection measures such retaining wall, slope easing have been applied. It is pertinent

Toe support for the affected slope through construction of strong RCC retaining wall with sufficient weep holes founded on sound substratum. Construction and proper maintenance of concrete road side drain.
Oversaturation of slope forming material and increase in local pore water pressure. Loose of toe support due to extensive slope cut along NH4. Weak lithology
