1. Systematic diversion of surface water runoff away from the depleted slope. 2. Construction of concrete lined hillside drains. 3. Construction of gabion wall at the toe of affected slope.

1. Hillslope highly dissected by drainages.2. SFM is predominantly composed of loose unconsolidated fragments of rocks (quartzite and mica chlorite schist) intermixed with soil. 3. Regolith thickness of >5 m. 4. Wet hydrological condition of the slope. 5
