The barren (snow covered) terrain comprises boulders of quartzite resting on slope predominantly composed of highly weathered rock mass, in-situ soil and rock fragments. Excavated slope for road construction, moderate steep slope, drainages on the hillsl
Kikon, A., and Jamir, I., 2021: Remote sensing based macro-scale (1:50,000) landslide susceptibility mapping in Toposheets 78M/9, M/10, M/11, M/13, M/14, M/15, 83A/2, A/3, A/4, A/7, A/8, A/11, A/12, 83B/1, B/5 & B/9 covering  parts of Tawang, West Kameng
Slope failure of the same nature as AR/WKG/83A03/2021/029 & 030. Adequate mitigative measures must be planned and implemented on similar slopes and geological condition.

1. Removal of unstable boulders from the affected slope. 2. Existing stone retaining wall may be upgraded to RCC retaining wall of adequate dimension. 3. Systematic channeling of surface water runoff away from the affected slope.

1. SFM: large boulders of quartzite resting on slope predominantly composed of highly weathered muscovite schist and quartzite, in-situ soil and fragments of rock. 2. Hillslope is moderately dissected by drainages.
3. Oversaturation of slope material and
