In urban areas experiencing intense rainfall, inadequate drainage network capacity can lead to runoff flooding from manholes, resulting in urban floods and disruptions to various infrastructure, including road networks. Developing a fast and robust model is essential for addressing this functionality failure in urban drainage networks (UDNs) and enhancing resilience. This research introduces a novel method for calculating flood volume in urban drainage networks using the graph theory method. The graph- based approach proposes modified graph metrics to rout the runoff in conduits, enabling the identification of overflow conditions for accurate flood calculations. This methodology is applied in a real case study in an alpine city area, and the resilience values calculated for rainfall durations of 10, 15, 20, and 30 minutes, along with return periods of 1 to 100 years, demonstrate a strong consistency with results obtained from a stormwater management model (SWMM) utilizing dynamic wave methods for flow routing.
