GIS Approach To Landslide Hazard Mapping: A Case Study Of Syangja District In Western Nepal

Landslides are one of the main natural disasters in Nepal. The annual loss of lives and property due to landslides and floods is significantly high in Nepal. The landslide hazard mapping is essential for delineating hazard-prone areas. The landslide hazard maps are very useful for planning, development, and disaster management. For mitigation and management of landslide disaster, hazard maps provide important information on landslide susceptibility condition of certain region. On the other hand, the landslide hazard maps are prepared using different methods. This paper discusses some of the hazard mapping used in Nepal. It also attempts to present the GIS approaches for hazard mapping using statistical method and describes in brief a case study from Syangja District located in western Nepal.
