Determining the optimal directions for the physical growth of Kermanshah according to the risk of landslides

Abstract

Kermanshah is one of the most populous cities in the country which has experienced rapid physical development over the years, therefore, paying attention to the issue of risks in planning its future expansion can be a vital issue. In this study it was tried considering the effective factors in landslides including lithology, soil science, Precipitation, distance from fault, altitude and slope, also use from the method of hierarchical analysis to determine the appropriate aspects of future physical development. First, the data used were prepared, after performing the method steps Hierarchical analysis of the weight of each criterion was identified. Finally, the layers used with the weights obtained from the hierarchical analysis method Finally, the layers used with the weights obtained from the hierarchical analysis method According to the results, the lithological criterion with a value of 0.445 was the most important criterion, According to the zoning map, the most suitable direction for The physical development of Kermanshah is east and northwest of the city. The results also showed that the core of the city was formed in a safe place, but over time has shifted to risky areas.
