The slide is a shallow translational debris slide caused due to extensive slope cut for rail line construction, triggered by incessant rainfall. The overburden material comprises of highly weathered ferruginous sandstone (W4) and insitu soil cover on top

1. Maintenance of existing toe wall by providing weep holes to allow passage of water. 2. Slope benching along the slope and construction of two tiers RCC retaining wall within clay beds with sufficient weep holes. 3. Use of geofibre with plantation of v
1. Slope cut 2. Poor slope forming material comprising of highly weathered ferruginous sandstone (W4) with thin clay beds. 3. During rainfall the weak material loses its cohesive strength leading to increase in pore water pressure causing slope failure.
