Debris slide documented along Pakke-Bameng road caused due to overburden (2m), rainfall. Aggravated by steep slope cutting and toe removal and predominance of thick insitu material on the upslope.
Mohanty, A., and Joshi, K., 2021: Remote sensing based macro scale (1:50,000) landslide susceptibility mapping in toposheets 82D/12, D/15, D/16, 82H/3, H/4, H/6, H/7, H/10, 83A/1, A/5, A/6, A/9, A/10, A/13, A/14 and 83E/1 covering parts of Tawang, West K

Pakke-Bameng Road
Hill side drainage, removal of debris. Construction of breast wall with adequate number of weep holes and lined hill side drainage to prevent toe erosion.
Loose un-compacted/less compacted OB, weathered rock mass, steep slope, saturation of the SFM due to rainfall, disturbance of natural equilibrium due to road cutting, are the causes of sliding. Aggravated by steep slope cutting and toe removal.
