Nowadays, the occurrence of extreme events and climate change, together with the expansion of human activities and encroachment on natural areas, have led to increased flood-related damages. Rural settlements, in particular, due to factors such as geographical location, environmental characteristics, physical-spatial structure, and level of development, often suffer the greatest losses when hazards occur. Therefore, in this study, based on an analysis of field visits to 1,418 villages across Iran, the vulnerability of rural areas to flood hazards was assessed. After identifying the most frequent solutions proposed for improving flood safety in these villages, one village was selected for detailed analysis, including a comprehensive safety plan and hydrological and hydraulic modeling. The results showed that 1,169 of the surveyed villages face flood risks, and the need for river and channel management was the most commonly recommended safety measure. Considering the widespread problems of inappropriate site selection and the expansion of construction along riverbanks, non-compliance with riverbed and floodplain boundaries, and especially the high costs of reconstruction and rehabilitation after floods, planning and action aimed at flood prevention and risk reduction—aligned with the National Disaster Risk Reduction Program—strengthening the integration of risk reduction measures into development plans, implementing river and channel management and safety projects in populated areas, and removing obstructive encroachments within riverbeds and floodplain boundaries are among the key priorities for effective flood risk management.
