Slope excavation for road construction, thick overburden, dissection of hillslope by major drainages, absence of systematic drainage system for proper disposal of surface water runoff, oversaturation of thick in-situ soil cover and loss of cohesion durin
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
The cut slope along this stretch is vulnerable to landslides due to thick overburden cover and drainages dissecting the hillslope.

Seppa Road Section
1. Systematic channeling of drainages and disposal of surface water runoff. 2. Proper maintenance of lined hillside drain.
1. Slope forming material is predominantly composed of moderately weathered and fractured rock mass overlain by thick cover of in-situ soil.2. Dissection of hillslope by major drainages. 3. Oversaturation, loss of cohesion and failure of in-situ soil col
