1. Removal of loose slided material and rock fragments at critical angle from the crown and slope surface. 2. Provision of hill side drainage. 3. Construction of retaining wall for toe support with sufficient weep holes.
1. SFM comprising of highly weathered, friable and fractured chlorite schist intermixed with soil. 2. Rill erosion on the slope face. 3. Oversaturation of SFM during rainfall leading to increase of pore water pressure and loss of cohesion.
