Landslide Hazard Zonation with Frequency Ratio Method (Case Study: Forest of Mazandaran Wood and Paper Industry)
The Landslide is one of the natural hazards that causes a lot of mortal and financial losses in high-altitude and seismic mountainous areas annually. Considering the importance of roads as a pillar of sustainable forest management in this study, we have tried to estimate the sensitivity of landslide occurrence in 8 forestry series with using frequency ratio approach. Initially, the slip positio...
متن کاملLandslide Susceptibility Mapping for Subalpine Grassland Using Frequency Ratio and Landslide Index Model (Case Study: Masoleh Watershed, Iran)
Subalpine ecosystems are highly fragile as compared to biological andenvironmental factors. Landslide is one of the ruinous upshots of this ecosystem. One of theimpressionable areas in the cause of natural factor is Masoleh watershed in western AlborzMt, (Iran). In order to landslide hazard zonation, landslide index and frequency ratio methodbased on twelve causative factors such as slope, slop...
متن کاملLandslide hazard zonation using of model Shannon entropy(case study: Taleghan watershed)
Reviewing the damage caused by landslide proves the need to examine the factors influencing the occurrence of this phenomenon and the prediction of its occurrence. Therefore, the purpose of this study was to improve the prediction of landslide occurrence in the Taleghan watershed using Shannon Entropy Theory. Among the factors influencing the occurrence of landslide, ten factors of elevation, s...
متن کاملthe comparison of the frequency ratio model and fuzzy membership functions in landslide hazard zonation (case study:marivan - sanandaj road)
introduction the natural phenomenon events are involved with several natural and unnatural factors that play a specific role in it event. landslides, is example of such natural phenomena that resulted from interaction of various factors. understanding the impact and weight of each factor by mathematical models can be solution for landslide study in term of zonation and extraction. landslides ar...
متن کاملFuzzy Approach to Landslide Susceptibility Zonation
The paper addresses a landslide-prone area on Fruška Gora Mt. in NW Serbia. It proposes a model of relative landslide susceptibility based on fuzzy sets. Having a variety of spatial attributes (proven statistically significant) at disposal, as well as present landslide inventory map, we conducted systematic analysis through (i) assigning fuzzy memberships to attribute categories, and (ii) combi...
