This project demonstrates how an integrated ontological and parametric modeling framework can be used to evaluate resilience in an urban emergency water distribution system under varying demand and disruption scenarios. By organizing five civil engineering subsystems, building demand, water supply, elevated storage, pipe networks, and road-based emergency trucking, around a shared, demand-driven backbone, the model enables consistent assessment of service availability, redundancy, and system interactions within a single coherent logic.<\/p>\n\n\n\n

A key contribution of the project is the explicit identification and resolution of integration challenges arising from differences in subsystem scale, assumptions, and performance measures. These challenges were addressed by anchoring all systems to a common demand variable and consolidating performance evaluation through a central integrator node. This approach ensures that each subsystem contributes transparently to total service delivery and allows their limitations to be directly compared, consistent with system-of-systems resilience frameworks where overall performance emerges from interaction rather than isolated optimization (Bruneau et al., 2003).<\/p>\n\n\n\n

System behavior was evaluated using clearly defined high performance criteria<\/strong>, including total water supply capacity, service ratio, and days of autonomy. These metrics allowed resilience to be assessed not only in terms of whether demand is met, but also how reliably and efficiently it is met under normal, disrupted, and extreme operating conditions. The parametric evaluation of low, medium, and high population growth alternatives revealed that resilience outcomes depend on balanced infrastructure scaling rather than maximizing individual component capacity.<\/p>\n\n\n\n

Results show that elevated water storage provides the greatest resilience benefit, as increased storage volume directly translates into longer autonomy periods and more stable service during disruption. While primary supply and pipe conveyance were sufficient to meet demand under normal conditions across all growth scenarios, disruption scenarios exposed the limits of road-based emergency trucking. Although trucking provides essential redundancy when pipe-based systems fail, its performance is constrained by operational and capacity limitations, leading to diminishing returns as demand increases. These findings reinforce established guidance that emergency delivery should function as a short-term contingency rather than a primary resilience strategy (American Water Works Association [AWWA], 2019; World Health Organization [WHO], 2017).<\/p>\n\n\n\n

An important outcome of the integrated model is the ability to compare systems using performance relative to material investment. By expressing buildings, tanks, and roads through service delivered per unit of material, the framework distinguishes resilience achieved through effective system configuration from resilience achieved through overdesign. This supports transparent decision-making when resilience, cost, and constructability are simultaneous design constraints and aligns with contemporary infrastructure resilience and sustainability objectives (Reed et al., 2009).<\/p>\n\n\n\n

Overall, the project confirms that resilient emergency water systems emerge from integrated, demand-responsive investments rather than isolated subsystem optimization. By combining ontological clarity with parametric flexibility, the proposed framework provides a robust and adaptable method for evaluating emergency water distribution strategies and supports the design of materially efficient, high-performing, and resilient urban infrastructure systems.<\/p>\n\n\n\n
