Slip phenomena zoning with using lnrf in Haraz Road (from emamzadeh hashem until larijan)

Landslide always as one of the environmental hazards to human activities is considered. Hence the study and understanding of the causative factors, and control any practical purpose is considered. Landslide zoning is one of the ways it can help identify critical areas and zoning maps obtained can be used in planning. In this study, target, investigate the causes of landslide events and evaluate the occurrence of this phenomenon through mathematical models and a road lie to the emamzadeh Hashem until larijan. Because of the large landslides occur in this area, the lands, residential areas and communication routes, such losses can be entered. Therefore, the aim of identifying the causative factors and landslide zoning resonator and finally through a model has been. To achieve this goal, first and most important factors affecting the slip phenomena such as slope, aspect, lithology, fault distance from the road, and inherited land. Have been studied and have been in digital ILWIS software. Then, using aerial photos and field visits, and GPS all existing landslides in the basin have been identified on the map. The landslide area and percentage in different classes and determine the model parameters obtained LNRF as little weight factors of maps has been prepared based on weighted values. Finally, the weight of the maps made in the model based on the weight of cumulative chart data breakpoints, the final zoning map landslide is obtained.
