Summary: This study establishes a theoretical framework and proposes an integrated methodology to evaluate the societal impact of disrupted infrastructure in disaster events. The societal impact is based on a water analysis, defined as the percentage of the population in different levels of need satisfaction depending on the amount of water people can obtain. The proposed engineering model combines water supply resilience analysis to estimate water quantity during a disaster event.

Summary: This study proposes a novel mathematical model to estimate the societal impact of water disruption quantitatively, focusing on tolerance level and activity choices. By prioritizing activities with the maximum suffering level, the model predicts individual's activity choices when water is limited. Monte Carlo simulation is used to generate simulated residents with randomly sampled tolerance levels, allowing for calculation of societal impacts.

Summary: This study investigates the societal impacts of infrastructure system disruptions on households. The results show that the impact on households increases nonlinearly with the duration of the disruption, and electric power disruptions have a greater impact than water supply disruptions. Unhappiness is better able to distinguish the effects of shorter-duration disruptions compared to willingness to pay. Additionally, factors such as the use of medical devices, worry about emergencies, and lower level of preparation are associated with increased household impact. Financial, time/effort, health, and stress concerns significantly influence the level of unhappiness.

Summary: With the increasing use of electric vehicles and the development of EV charging stations, it is crucial to assess the potential impact of intensive EV charging on power distribution systems. This research focuses on a rural area in west Kentucky and uses software tools to investigate the impact of EV charging on distribution system operation and the lifetime of power transformers. The findings help identify risks of system overload and propose mitigation solutions for future EV charging needs. Overloading and undervoltage violations in the distribution systems are examined, and a reliability analysis is conducted to study the overload impact on transformers.

Summary: This study quantified the societal impacts of infrastructure disruptions by considering people's achievement/intolerance of survival-related activities and proposed an agent-based societal impact simulation model (ABSISM) for quantitative estimation of the impact. The ABSISM incorporated dynamic interactions between households' emergency behaviors, infrastructure disruption, and government countermeasures in typhoon disaster scenarios and designed decision rules for three types of agents: household, store, and shelter agents.

Summary: This paper analyzes the degree of centralization of generators in the contiguous U.S. between 2001 and 2018 and identifies the state level policies that may drive differences in the degree of centralization. The results show that some state policies have driven greater decentralization of generation while others have not. The degree of centralization of generation assets has implications for sociotechnical systems, communities, energy security, and resiliency against manmade and natural disasters.

Summary: The widespread use of electric bidets in Japan and other regions has implications for water infrastructure, and this study evaluates the impact and predicts future scenarios. The survey findings reveal that a significant number of respondents express concerns about sanitation, despite the prevalence of electric bidets in Japan. However, when taking into account actual usage, the environmental impact of current electric bidet models is shown to be minimal.

Summary: The focus of building functionality design should be on meeting the safety and well-being needs of occupants, guided by research conducted by social scientists. Architects should work collaboratively with engineers to ensure the services provided do not exceed acceptable levels for different weather conditions, with onsite power generation and storage being a critical aspect of the formulation. The proposed approach aims to transform the existing multidisciplinary approach into an interdisciplinary one through interactions among architects, social scientists, and engineering disciplines.

Summary: This paper proposes a coordinated restoration framework for a coupled power and water system, considering physical networks and mechanisms. The framework minimizes the aggregate service loss with respect to different consumer loads and time periods by network reconfiguration, energy/water dispatching, load curtailment, and operation management of components. A two-stage risk-averse stochastic programming is applied for reliable restoration and manage risks.

Summary: The developed computational framework supports government decision-making in hurricane risk management by modeling regional natural catastrophe losses dynamically and stochastically. It includes various interacting models to simulate hazard events, estimate losses, capture homeowners' behaviors, and represent an insurance market. The framework can optimize decision-making to minimize hurricane losses by coordinating insurance, retrofit, and acquisition policies effectively.

Summary: Disaster events can expose the vulnerability of telecommunications infrastructure, leading to prolonged service disruptions. Understanding how people adapt to these disruptions can provide valuable insights for disaster preparation and response. In this research, the authors used Twitter data to examine how people in Puerto Rico adapted to extended telecommunications disruptions after Hurricane Maria in September 2017. They applied machine learning techniques to detect adaptations to telecommunication disruptions in the Twitter dataset, and used qualitative coding to analyze the different ways people adapted to disruptions in cell service, Wi-Fi access, and electricity for communication devices. The findings highlight the willingness of affected individuals to go to great lengths to access telecommunication services, as well as shifts in reliance on existing infrastructure.

Summary: Wind fragility curves were developed to investigate the effects of roof shape and pitch on roof sheathing performance. It was found that complex roof shapes are more susceptible to damage for gable roofs, while roof shape has minimal effect on hip roofs. Additionally, roof pitch has a greater impact on gable roofs than on hip roofs, with higher pitch angles leading to lower probability of roof sheathing failure.

Summary: Today's regional natural hazards loss models seldom consider changes in the built environment over time, leading to underestimated natural hazard risk assessments. Available models that account for changes in the built environment lack a sufficiently granular spatiotemporal scale for regional natural hazards loss modeling. This study introduces the Housing Inventory Projection (HIP) method, which includes modules for estimating the annual housing units per county and the likely location of future single-family housing units. A case study in North Carolina estimates the number of single-family houses per 1 km(2) grid cell from 2020 to 2049, revealing increased construction in flood-prone areas.

Summary: This paper investigates the household adaptations and reactions to the power and water supply interruptions caused by a winter storm in Texas. The study finds that almost everyone implemented at least one adaptation and the most common adaptations included using candles, flashlights, and/or lanterns, charging cell phones in the car, purchasing bottled water, and delaying or reducing consumption. The level of unhappiness varied with the duration of the outages and household characteristics, and financial, time/effort, health, and stress concerns influenced the extent of unhappiness.

Summary: Evacuation destination choice modeling is crucial for evacuation planning, but it has not received enough attention. This study presents a new approach using smartphone location data to identify evacuees and determine their destinations and timing, and develops a machine learning model that predicts the number of evacuees between different areas. The model outperforms traditional gravity models, and hurricane characteristics are found to be important in evacuee destination choices.

Summary: The study found that coastal populations are more likely to evacuate during hurricanes compared to inland populations. The difference in evacuation rates cannot be fully explained by geographic factors and receipt of evacuation orders. Risk perception may also contribute to the difference in evacuation behavior between inland and coastal populations.
