Abstract :
Siah khor basin locating on the outskirts of Western Islam Abad enjoys a wide variety oflandslides which have posed a threat to pasturelands and implementing watershedmanagement plans in the area. Studying the landslide condition in the region, its zonation aswell as identifying the areas which are more sensitive to landslides and also specifying themount of relocation and the its relevant mechanisms will enable us to control andpredict preventive action in response to the possible dangers in the future. landslides andstudying the factors and elements causing them can result in rapid and better control ofthem.In this research we have tried using AHP application model based on the optimalexpertise in the area of Seahkhor Basin landslide zonation map extracted. For this purpose, aDelphi consensus techniques, GIS and multi-criteria decision making is used. Analysis resultsshow that factor analysis, hierarchical in Seahkhor Basin, geology, land use, and precipitation,the most important parameters influencing landslides in the area are the Seahkhor Basin.Seahkhor Basin landslide zonation map of the area shows a total of more than 70% of criticaland semi-critical status and potential of the landslide. The landslide distribution in North,North East, Central and South West areas of special geological and topographical conditionsas well as changes in land use is indiscriminate. The management of mass movements in theseareas should be considered further.
