Abstract
Flood is one of the most common natural hazards that causes many human and financial losses all over the world every year. In order to reduce the damages caused by floods and flood management, it is necessary to assess the possibility of danger and prepare maps of possible danger areas. Flood-flooding potential zoning is one of the methods that can be adopted to reduce the risks caused by floods. In recent years, many destructive floods have occurred in Garami county. For this reason, in order to manage floods, reduce damages and use water resources correctly, the flood potential of Germi county has been studied. In this study, 9 factors of slope, slope direction, height, precipitation, distance from the river, density of the river, lithology, distance from the city and village and land use were identified as effective factors for causing floods in the region. Standardization of maps was done using fuzzy method and zoning of prone areas was done with Aras multi-criteria algorithm in Edrisi software environment and according to the results of flood risk zoning; The criteria of lithology, land use, slope, distance from the river are the most important factors involved in creating the risk of subsidence of the study area with the weight coefficient of 0.853, 0.808, 0.674 and 0.4867 respectively, and 189.70 and 189.70 respectively. 20/388 square kilometers of the area has a very high probability of danger.
