Abstract :

Flood is one of the important natural disasters that causes a lot of financial and human losses every year, and in order to reduce its losses and casualties, it has always been the attention of managers and planners. The purpose of this research is to prepare a flood risk zoning map in Nowshahr city. In this study, in order to achieve the goal of the research, first by studying and investigating the theoretical foundations of the subject, the effective factors in the occurrence of floods, including height, slope direction, slope, waterway density, distance From the river, soil, land use, geology, slope curvature, land type and precipitation were identified. Then, the maps of each of the mentioned criteria were prepared in Arc GIS 10.5. After preparing the layers of the effective factors in the occurrence of floods, using the opinion of 25 experts in this field, the layers and sub-criteria were weighted using the fuzzy hierarchical method. And in the last step, the obtained weight of each factor was applied to each of the layers in the ARC/MAP software environment, and the zoning map of flood risk was prepared using the fuzzy logic of the 0.9 gamma operator. According to the results of Vozandhi, the factors of rainfall, distance from the river, slope and land use are the most important factors of flood in the region. The zoning map shows the risk of flooding in Nowshahr city.
