Abstract

Landslides are the natural events that affect the various factors causing damage to nature, human and facilities. One of the susceptible areas of this natural process is VAZ watershed in North of Iran. For LANDSLIDE HAZARD ZONATION Certain Factor, INFORMATION VALUE and ANALYTICAL HIERARCHY PROCESS (AHP) Models were used by applying GIS software. First the landslide distribution map was prepared by field observation with the map of different factors in landslides. AHP method was used for determining factors priority. Lithology, distance from the road, slope, distance from waterways and land use were the most important factors in landslide occurrence. In the next step, CERTAINTY FACTOR, INFORMATION VALUE and AHP models used to preparing landslide hazard map in low, medium, high and very high classes. The validation of methods showed that certain factor, INFORMATION VALUE and AHP respectively have the highest precision in preparing the landslide hazard map.53.34% and 20.28% of the area located in high hazard and low hazard respectively, which indicate the high susceptibility of the area to landslide hazard.
