Flood Resilience Assessment of Urban Drainage Systems: A Graph Theory Perspective University of Innsbruck, Department of Infrastructure, Unit of Environmental Engineering, Innsbruck, Austria In urban areas experiencing heavy rainfall, inadequate drainage system capacity can result in runoff overflowing from manholes, triggering urban flooding and disruptions to essential infrastructure, such as roadways. Developing a fast and robust model is crucial in addressing this functionality failure in urban drainage networks (UDNs) and enhancing resilience. This research introduces a novel method for calculating flood volume in UDNs and evaluating their resilience using graph theory. The proposed graph-based approach employs modified graph metrics to route runoff through conduits, accurately identifying overflow conditions for precise flood volume calculations. Applied to a real-world case study in an alpine region, the resilience values were calculated for rainfall durations of 10, 15, 20, and 30 minutes across return periods ranging from 1 to 100 years. The results demonstrate a strong consistency between the graph-based approach and the Storm Water Management Model (SWMM) utilizing dynamic wave methods for flow routing, highlighting the effectiveness and reliability of the proposed methodology. | |
