Fig.1. Location of the study area- Kolli hills. the foothills of Karavallikkombai to Sholaikkadu at the top is selected for the present study as shown in Figs.1 and 2. The Ghat road was constructed along cut slopes by modifying the original natural slope. Hence, most of the hairpin bends are associated with vertical rock cut slope and soil profiles. The vertical profiles exposed to weathering and soil erosion (Ramesh and Anbazhagan, 2014) over the period, ed to slope instability. The Ghat road fall in between 11°18'29.72"N and 11°19'50.38"N latitudes and 78°19'30.99" E and 78°21'6.49"E ongitudes. The Survey of India (SOI) topographical map 58 I/7 cover the study area. This region has experienced several major and minor landslides. The available data indicated that the frequency of andslide occurrences was noticed once in 8 years. In Kolli hills, major landslides occurred in the year 1992, 2000, and 2008. It is
