A graph-based approach for structural resilience assessment in urban drainage networks University of Innsbruck, Department of Infrastructure, Unit of Environmental Engineering, Innsbruck, Austria This study addresses the significant challenge of pipe blockage in Urban Drainage Networks (UDNs), commonly caused by sediment transfer during runoff. Such blockages can lead to flooding, even during low-intensity rainfall, thereby disrupting life in urban areas. To tackle this issue, a novel graph-based approach is proposed that converts the UDN into a graph network, enabling the identification of critical pipes for strategic interventions. By implementing modified graph theory metrics, flood volume and total runoff were calculated for single-pipe failure scenarios, facilitating the assessment of UDN resilience. The methodology is validated through a real-case study, analysing return periods of one and two years under varying durations of 10, 30, and 60 minutes. Results demonstrate that the graph-based method exhibits a high degree of consistency with the established stormwater management model (SWMM), highlighting its potential as an effective tool for improving UDN resilience. | |
