LANDSLIDE HAZARD MAPPING AND ITS EVALUATION USING GIS: AN INVESTIGATION OF SAMPLING SCHEMES FOR A GRID-CELL BASED QUANTITATIVE METHOD

An application of GIS for landslide hazard assessment using multivariate statistical analysis, mapping, and the evaluation of the hazard maps is presented. The study area was the Kulekhani watershed located in the central region of Nepal. A distribution map of landslides was produced from aerial photo interpretation and field checking. To determine factors influencing landslides, layers of topographic factors derived from a digital elevation model, geology, and land use/land cover were analyzed by quantification scaling type II analysis, and the results were used for hazard mapping. Effects of different samples of landslide and non-landslide groups on the critical factors and classes and later on hazard maps were evaluated. Results and implications regarding the practical use of hazard maps are provided and discussed.
