Abstract
Floods are known as one of the most common and destructive natural disasters due to widespread destruction and huge economic losses. Khorramabad city is one of the cities at risk of flooding due to the experiences of floods in recent years and the location of the city in a valley, heavy rains, the presence of rivers in the city(Khorramrod and Karganeh), manipulation of the boundaries and bed of rivers.Therefore, investigating flood vulnerability plays an important role in reducing the damages and risks caused by floods.One of the methods of investigating and analyzing flood vulnerability and urban facilities exposed to floods is the use of fuzzy hierarchical analysis process (Ahp Fuzzy) in order to identify flood-prone and flood-vulnerable areas.Therefore, in this research, the method of fuzzy hierarchical analysis process was used to prioritize the criteria. In this research, from 12 criteria (worn texture, population density, road network, land use, height, slope, direction of slope, geology, distance from the river, soil science, Land subsidence and rainfall) were used to prepare a map of flood-prone and vulnerable areas.The results of the analysis of this research showed that 38.17% of urban facilities are exposed to high and very high vulnerability, and administrative, commercial, and educational uses have the highest level of vulnerability compared to other uses to flooding.To reduce vulnerabilities, especially reducing the vulnerability of facilities to flooding, suggestions can be made such as: improving the physical quality of urban facilities and buildings, organizing and improving the quality of river beds and boundaries, and the condition of drainage, and finally using smart and advanced technologies to predict and warn of floods in order to reduce vulnerabilities
