Multiple debris slide along Pachi-Pakke road due to lose overburden material and weak slope forming material. Incessant rainfall caused the weak slope forming material unstable, leading to failure.

Construction of benched/stepped gabion walls from the down slope along the face of the slide for ready passage of water through the porous wall. In addition, it is recommended to provide lined hillside drainage system. Also the nala should be channelized
Reduction of strength on saturation by seepage from rainwater Also a nala flows along the left flank which also caused seepage inside. The material above and below the road is largely loose unconsolidated. Construction of road, anthropogenic activities a
