Abstract

Haraz watershed located in the north of Iran has high LANDSLIDE capacity. However, the available information on LANDSLIDEs in this watershed is still limited. The purpose of this research is LANDSLIDE hazard mapping using CERTAINTY FACTOR, INFORMATION VALUE and AHP models in GIS environment in a part of HARAZ watershed. For LANDSLIDE susceptibility mapping, at first, LANDSLIDEs distribution map and effective factors map were supplied by field study, and then prioritization of effective factors was carried out using AHP. The investigation indicates that lithology, distance from road, slope, distance from drainage network, land use, elevation and aspect are the main LANDSLIDE controlling factors in the area. In the next stage, LANDSLIDE hazard map was provided using these factors as well as CERTAINTY FACTOR, AHP and INFORMATION VALUE models. Evaluation of these models showed that CERTAINTY FACTOR, AHP and INFORMATION VALUE models have the highest accuracy for LANDSLIDE hazard mapping, respectively.
