Resilience enhancement of water distribution networks under pipe failures: a hydraulically inspired complex network approach J. Water Supply Res. Technol (IF 4.3) Pub Date : 2023-12-01 Mohsen Hajibabaei, Azadeh Yousefi, Sina Hesarkazzazi, Amin Minaei, Oswald Jenewein, Mohsen Shahandashti, Robert Sitzenfrei
View largeDownload slide View largeDownload slide Close modal The resilience of water distribution networks (WDNs) should be proactively evaluated to reduce the potential impacts of disruptive events. This study proposes a novel hydraulically-inspired complex network approach (HCNA) to assess and enhance WDN resilience in the case of single-pipe failure. Unlike conventional hydraulic-based models,
