INTRODUCTION: Flood is a natural hazard with the highest frequency and the widest geographic distribution around the world. Indiscriminate exploitation of forests and pastures, changing the land use and turning them into unsuitable agricultural lands, along with the indiscriminate construction of residential areas, have caused an increase in floods. This article is done with the aim of prioritizing flood vulnerability criteria in Qirokarzin city in Fars province.
METHODS: In this descriptive-analytical research, priorities and effective criteria were selected through library studies, examining various sources, as well as the Delphi technique, then, the opinion of experts and specialists was asked and prioritization was done using a questionnaire.
FINDINGS: The findings of the research indicated that 12 effective criteria in the occurrence of floods in the study area are: land use, streets and public roads, distance to the river, soil texture, amount of precipitation, not respecting the boundaries and development of urban areas towards the rivers, high runoff coefficient in the areas residential, low width of the communication network, population density, type of building materials, slope of the land and overall capacity of flood control. In the following, for each criterion, the graph of importance percentage and degree of importance was drawn, and finally, based on that, the priority of the effective criteria in the study area was determined.
CONCLUSION: According to the results obtained, appropriate structural and non-structural measures should be taken to minimize flood damage as much as possible. Therefore, managers and executives should consider appropriate management plans to reduce flood damage and include its results in regional development planning programs.
