Abstract The resilience of water distribution networks (WDNs) should be proactively evaluated to reduce the potential impacts disruptive events. This study proposes a novel hydraulically-inspired complex network approach (HCNA) assess and enhance WDN in case single-pipe failure. Unlike conventional hydraulic-based models, HCNA requires no hydraulic simulations for analysis. Instead, it quantifies failure consequences edges (pipes) on graph by incorporating topological attributes with flow redistribution triggered failures. procedure leads identification critical (pipes), as well impacted ones, representing more susceptible others. are then systematically resized integrating graph-based design approach, obtaining wide range enhancement solutions. A comparative between model three WDNs confirms HCNA's effectiveness identifying most pipes various sizes. Furthermore, provides comparable solutions evolutionary optimization but significantly lower computational effort (1,400 times faster). Thus, can efficiently used large-scale WDNs, where application optimizations is limited due intensive workload.

Evaluating the seismic resilience (SR) of water distribution systems (WDSs) can support decision-making in optimizing design, enhancing reinforcement, retrofitting efforts, and accumulating resources for earthquake emergencies. Owing to complex geological environment, buried supply pipelines exhibit varying degrees corrosion, which worsens as age, leading a continuous degradation their mechanical performance, thereby impacting SR WDSs. Consequently, this study proposes an evaluation method WDSs that takes into account corrosive environment service age pipelines. Utilizing analytical fragility analysis method, research establishes curves various ages diameters diverse environments, combination with Monte Carlo simulation generate damage scenarios Furthermore, post-earthquake satisfaction is utilized characterize system performance (SP) Two repair strategies are employed damaged pipes: assigning single crew address damages sequentially deploying each location simultaneously, assess minimum maximum values The application results indicated decrease SP across 36 conditions was 32%, lowest value being 0.838. Under identical intensities, varied by much 16.2% different soil conditions. rare conditions, effect significantly outweighs impact on Post-disaster restoration minimize

ABSTRACT Water distribution networks (WDNs) are critical infrastructures prone to vulnerabilities which lead failures. Identifying vulnerable components, especially multiple pipe failure combinations, is crucial for effective management and ensuring high reliability. Hydraulic simulations commonly used analysing the criticality of WDN, but time-consuming highly data-reliant, limiting number testable combinations. To address these limitations constraints, a graph-based method proposed quantify impact magnitude scenarios on performance, enabling identification The approach utilizes structural topological characteristics WDNs as well spatial demand replicate hydraulic behaviour. accuracy assessed by testing it three case studies with various results compared analyses. demonstrate strong correlation (Spearman coefficient > 0.75) between ranking state-of-the-art hydraulic-based ranking. Additionally, exhibits significant computational gain factor greater than 30 method, rendering valuable actively exploring wide range combinations devising countermeasures. Furthermore, hybrid-based that integrates both graph methods enhanced robust assessments.

Large earthquakes often damage water pipelines and disrupt the functionality of distribution systems (WDS). This paper investigates hydraulic performance WDS following an earthquake, taking into account postearthquake firefighting capacity system corrosion deterioration pipelines. The seismic failure probability for corroded pipes is calculated using a modified American Lifeline Alliance fragility function, simulations are performed network tool resilience. Water serviceability generalized resilience index used as measures to determine WDS, which evaluated under various conditions ages intensities. framework developed in this study exemplified Zhi Jiang (ZJ) WDS. results indicate that, although does not significantly reduce measures, it necessary consider recovery plans since more customers likely lose supply due fires. behavior worst older or those subjected higher magnitudes. Due scenario earthquake event, reduces ages, networks require longer times. Therefore, has significant influence on system-level performance.
