Inventory of Active Landslides and Landslide Hazard Assessment Using Field Techniques and Remotely Sensed Data: A Case Study from Balkhila Sub-Watershed (Uttarakhand, Himalaya)

This paper presents landslide hazard assessment in and around Balkhila sub-watershed of Uttarakhand, Himalaya using remote sensing data and Geographical Information System. IRS-IC LISS III, RESOURCESAT LISS-IV remote sensing data products along with Survey of India (SOI) topographical sheets accompanied by field investigations were used to generate a landslide inventory map of the study area. Such type of information on slope stability of the area could be useful for explaining the known existing landslide, helping to make emergency decisions and relieving the efforts on the avoidance and mitigation of future landslide hazards in the area.
