Abstract
Today, the world is exposed to unprecedented natural hazards, and floods are one of the most important of them, which, given the spatial extent of their occurrence, have the potential to become hazards with a high level of vulnerability. Therefore, one of the significant issues with the risk assessment approach is urban floods, which needs to be examined from a systemic perspective in urban areas. Accordingly, the present study assessed and zoned flood risk in the urban area of Noorabad. In this regard, the research process was a combination of steps including determining the study area, identifying effective criteria in urban flooding including slope, slope direction, elevation, distance from the river, land use, lithology, precipitation, and slope curvature, weighting and prioritizing the floodplains based on their impact on the research problem, fuzzing the information layers based on fuzzy functions, and finally preparing a flood risk potential zoning map based on the FAHP model, and finally validating the model and field evidence. The results of the research showed that each criterion with its related sub-criteria played a role in the flood risk process in Noorabad to varying degrees, and among them, the criterion of distance from the river with a coefficient of 0.219 played the greatest role in flood risk. The final results from the zoning map showed that the majority of the study area, equivalent to 38%, is located in areas with high and very high potential for flood risk. Therefore, a significant part of the urban area of Noorabad has the potential for flood risk, and these flood zones are significant in the river areas and adjacent to rivers throughout the city. The more complementary results of this study showed that apart from the areas mentioned above, due to the cumulative role of effective parameters, especially topographic and physiographic conditions, a significant part of Noorabad city has medium to high flooding potential. Therefore, the present study serves as a database and in the process of completing data from previous studies regarding flood risk potential and identifying flood-prone areas in the urban area of Noorabad, and is useful for urban managers.
