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 more weep holes to allow passage of water and avoid clogging. 2. Slope benching along the slope and construction of two tiers RCC retaining wall with sufficient weep holes within sound bedrock or on the mo
1. Slope cut. 2. Poor slope forming material comprising of highly weathered ferruginous sandstone (W4). 3. During rainfall the weak material loses its cohesive strength leading to increase in pore water pressure causing slope failure. 4. Poor maintenance
