Abstract :

Landslide hazard is one of the major environmental hazards in geomorphic studies at mountainous areas. In order to help the planners in the selection of suitable locations to implement development projects, a landslide susceptibility map has been produced for the Golmakan-watershed as part of Binaloud northern hillsides (Northeast of Iran) using the Weighted Linear Combination (WLC) equation. For this purpose, after preparation of a landslide inventory of the study area some 15 major parameters were examined for integrated analyze of landslide hazard in the region. The analyses of parameters were done by Geo-reference and lateral model making and spatial analyses by using geographical information system (GIS). The produced factor maps weighted with analytic hierarchy process (AHP) method and then classified. The final produced map for susceptibility of landslide hazard in Golmakan-watershed revealed that: 1) the parameters of land slope and geologic formation have strong correlation (R2=0.79) and (R2=0.83) with dependent variable of landslide susceptibility respectively, (p<0.05). 2) About 18.8% of the study area has a minor and negligible susceptibility to future landslides, while 81.2% of the land area of Golmakan-watershed falls into the severe and moderate categories.
