A detail geotechnical study of landslides in an area of 7.92 sqkm in an around around the approach road to Kalimpong town in Darjeeling district, West Bengal, has been done in order to assay the slope instability factors.
The study included the identification of landslides and their detailed morphogenetic study with background of lithologic and structural features, nature of surface drainage, slope morphometry, lineament control, effect of antecedent rainfall and landuse.
The cumulative effect of all these factors was studied in each specific landslide location and then the slides were categorized according to the classification framed by Varnes (1978).
On assertaining the nature of slides and their related causitive facotrs, suitable remedial measures to control these individual slides have been proposed. based on the practiced procedures of landslide control.
