Simulation Dataset for Evaluating Evacuation Shelter Location Impacts on Water Access During Seismic Events

This contains the data and code used in a paper with the following abstract: "Supplying potable water and other services to critical facilities such as hospitals and evacuation shelters is crucial following disasters. Identifying areas at high risk for service loss and optimal shelter locations is challenging due to complex infrastructure networks, uncertain damage, and dynamic populations. This study presents a framework for analyzing the resilience of water infrastructure networks while considering the interdependencies between human behavior, evacuation shelter location, and infrastructure service availability. The framework provides opportunities to determine the likelihood of water service availability at shelter sites, how shelter location impacts services at other critical locations, and how evacuation patterns change which infrastructure components are most critical. The value of the framework is demonstrated with an analysis of probabilistic damage scenarios from a 250-year seismic event on a water distribution network for a small coastal town. Hydraulic performance is measured over 72 hours assuming 10 different possible shelter sites. Results show that water availability varied widely among evacuation sites, where average availability differed by as much as a factor of 2.6 between sites. Sites not reliant on pumps, along larger diameter pipes in looped sections, and closer to the water sources had more consistent water availability. Evacuation location can influence water availability at other critical locations, particularly when evacuation-driven demand is concentrated upstream of critical facilities in capacity- or redundancy-limited portions of the network. This research highlights the advantages of detailed evacuation scenario analysis as a decision-support tool and offers valuable insights into enhancing infrastructure network resilience through both network design and evacuation strategy."
