Landslide hazard zoning in Kaleh Shoor mountainous area, Neyshabour, Iran

A major part of Iran is mountanious and mass movements and landslides are one of the environmental hazards in mountains. Southern slopes of central Binaloud are more susceptible to landslides, and every year there are damages to farms and rural settelments due to landslides. These factors include: Geological formation, intensive landuse and humidity of area. This paper has paid attention to the effects of landslides using Anbalagan method and specified unit sub-basin element weights and ranks of landslide hazards. According to the maps and field study with GPS landslide hazard maps were drawn and results showed that about 64% of the area was located in intensive landslide hazard zone. A knowledge on the landslide hazard potentials might be of great importance for regional decision makers.
