Abstract

Summary

Landslide processes in the Himalayas represent a major hazard threatening both human lives and the socio-economic development of the region. The purpose of the present studies is to demonstrate the potential of the integrated technique for the assessment of the landslide hazards at the regional scale within the mountain areas (Central Nepal). An analysis of the factors favoring the occurrence of landslides is performed on the base of existing geological and remote sensing data. The Landslide susceptibility map of Central Nepal was created using the Weighted Overlay method. This method allows to take into account simultaneously the different factors to be considered (slope, distance to lineaments, geology, lithology, elevation) in order to obtain spatial information and to implement a multi-factor model for a comprehensive landslide hazard assessment. The developed prognosis models could be applied for better understanding of vulnerability of areas, and to apply the methods of local predictions of landslides within areas with the highest hazards. It enables to develop the appropriate protective measures to withstand the impact of potential landslides in Central Nepal.
