Abstract :

Introduction: The study area (Tefli village) is located in Kurdistan, Iran. According to Iran’s tectonics classification it is part of the “Zagros Fold Belt”. The aim of this study is to prepare a relative risk zoning map of hill slide instability and landslide in “Tefli” village. Methods: Initially, nine factors were identified as effective parameters on landslides in the study area, therefore the Phasing method was used in order to prioritize these factors and to make the landslides risk zone of the area. Results: The study showing that 63\14, 10\48, 11\52, 9\60 & 5\24 percent of the area classified to “very low, low, moderate, high, very high” risk zone respectively and “Road” and “Fault” defined as the most effective factors for landslides events. Conclusions: According to the geographical position of the area, formations type and topographic situation, the study area is located in an unstable and high potential of landslide hazard zone. Consequently, slope sustainability methods in unstable hill slides can be used in order to increase the safety of the area.
