"Cities must be resilient to maintain their essential functions and have the ability to return to their original state after severe events. Physical structures and foundational networks, commonly referred to as 'infrastructure,' play a critical role in the functioning of any society. Infrastructures are interdependent systems with various types of dependencies, and their mutual dependency can affect their resilience against extreme events. Water and transportation infrastructures in the metropolitan area of Tehran are densely located alongside each other from a geographic dependency perspective, which could lead to the propagation of failure from one infrastructure to another. Despite Tehran's high seismic activity, the city has continued to expand and is now one of the most vulnerable urban areas to earthquakes. The combination of high seismic risk, dense population distribution, concentration of services, and the emergence of social vulnerabilities makes Tehran one of the most significant metropolitan areas in the world at risk of earthquakes. Therefore, by reviewing previous studies on infrastructure dependency and adopting a socio-technical approach within an algorithmic framework, three objectives were outlined: Identifying vulnerable points at risk of earthquakes within the interdependent water and transportation infrastructure network in the metropolitan area of Tehran; Assessing the resilience of the metropolitan area of Tehran against earthquakes, considering the perspective of social vulnerability within the water and transportation infrastructure network; Providing practical solutions related to the resilience of the metropolitan area of Tehran, focusing on the resilience of critical interdependent water and transportation infrastructures. The research data were collected through the Statistical Center of Iran, the Statistics and Information Office of Tehran Province, and the open-source platform OSM. In the first phase, the algorithmic framework utilized the PCA model to identify rivers, canals, and roads with the highest scores and geographical proximity as vulnerable points. Then, based on the number of rivers, reservoirs, intersections, and roads that failed, the extent of failure in the water and transportation infrastructure network was determined. Subsequently, using the BART model and social vulnerability indices, land use data, and the extent of failure in each infrastructure network, the resilience level of each region was assessed. Firuzkuh, Varamin, Rey, and Shemiranat counties exhibited the lowest resilience levels compared to other areas in the metropolitan region of Tehran. After identifying the vulnerable points and assessing the resilience of the regions, solutions were provided to improve the resilience level of the metropolitan area of Tehran at three levels: individual, collective, and systemic, by adopting the theory of transformational resilience. In conclusion, the contribution of this research can be viewed as an attempt to formulate a specialized planning approach to address infrastructure dependency issues."
