Locating suitablesites for relief camps during severe floods using GIS (Case study: Chaharmahal and Bakhtiari province)

Abstract Natural crises are unavoidable, but the damage to the financial and human sectors can be greatly reduced by relying on engineering techniques and scientific innovations. Many parts of Iran are among the accident-prone areas in the world that need special attention before crises. Chaharmahal Bakhtiari province is one of these areas due to its geographical location and special climatic conditions, which makes the location of emergency accommodation for floods in this province important. In the present study, a method based on compiling a researcher-made questionnaire and reviewing library documents and statistical models has been used. Therefore, using Analytic Hierarchy Process (AHP) method, identify safe places during floods and prepare the existing criteria and sub-criteria, and then using the fuzzy-hierarchical statistical information (FAHP), the value values of each criterion and sub-criteria The final weight was calculated, and the relevant drawings were prepared and compiled in the GIS environment to display them as best as possible. The results showed that Shahrekord has the lowest level of risk among the cities of the province and the north and northeast of Borujen, Ardal and the central and southern parts of Koohrang and the northern parts of Lordegan have more safety than the northern parts of the city, respectively.
