چکیده

Resilience of urban systems against floods means the stability and resistance of these systems against damage caused by floods and their ability to recover and quickly return to normal conditions after occurrence of a natural disaster, i.e. floods. One of the important issues faced by settlements, especially metropolises, in recent decades, despite the large population and physical density, is natural hazards, including urban floods. Resilience against urban floods is one of the important and complex issues in Studies of water and hydraulic structures have recently attracted the attention of many researchers, because by examining this concept, resilient and non-resilient points can be determined and efforts can be made to maintain and increase its resilience. Since the increasing population in Tehran city has created problems and challenges in terms of urban flood management, the researchers of this study tried to measure and interpret the important and influential components of resilience in the hydraulic index. The purpose of this research is to evaluate urban resilience against natural hazards with an emphasis on urban flood management in Tehran city. The research results show that Tehran's districts 22, 20 and 5 have the most resilience and districts 9, 10, 11 and 17 have the least resilience in terms of the hydraulic component among the regions
