Mass Movements Hazard Zonation with Fuzzy model (Case Study Shahrestanak Bsian)

P١r٣eparation of landslide susceptibility maps is important for engineering geologists andgeo m١٤orphologists. However, due to complex nature of landslides, producing a reliablesus c١e٥ptibility map is not easy.Amang various models , a research study with objective ofrec o١g٦nizing factor affecting landslide and determination of lands with hypothential to itsocc u١r٧rence was conducted to prepare landslide zonation map for the Shahrestanak watershedfuz z١y٨ method. In order to determine the most important factor affecting landsliding differentwe re١ ٩prepared digitally using aerial photos with scale of 1:50000 for the year of 1957 and20 03٢٠ respectively together with field checks using GPS.Then Preparation of landslidesus c٢e١ptibility map using Fuzzy logic method . Results of this study show that consideringnu m٢e٢rous factors for landslide evaluation at the same time in comparison to the otherpre v٢a٣lent method and investigation showed that most recorded landslides in the area haveocc u٢r٤red in zones marked as susceptible in the offered model.
