National Inventory

Aging water infrastructure in the United States (U.S.) is a growing concern. In the U.S., over 90,000 dams were registered in the 2018 National Inventory of Dams (NID) database, and their average age was 57 years old. Here, we aim to assess spatiotemporal patterns of the growth of artificial water storage of the existing dams and their hazard potential and potential economic benefit. In this study, we use more than 70,000 NID-registered dams to assess the cumulative hazard potential of dam failure in terms of the total number and the cumulative maximum storage of dams over the 12 National Weather Service River Forecast Center (RFC) regions. In addition, we also estimate potential economic benefits of the existing dams based on their cumulative storage capacity. Results show that the ratios of the cumulative storage capacity to the long-term averaged precipitation range from 8% (Mid-Atlantic) to 50% (Colorado), indicating the significant anthropogenic contribution to the land surface water budget. We also find that the cumulative storage capacity of the dams with high (probable loss of human life is if the dam fails) and significant (potential economic loss and environmental damage with no probable casualty) hazard potential ranges from 50% (North Central) to 98% (Missouri and Colorado) of the total storage capacity within the corresponding region. Surprisingly, 43% of the dams with either high or significant potential hazards have no Emergency Action Plan. Potential economic benefits from the existing dams range from $0.7 billion (Mid Atlantic) to $15.4 billion (West Gulf). Spatiotemporal patterns of hazard potential and economic benefits from the NID-registered dams indicate a need for the development of region-specific preparation, emergency, and recovery plans for dam failure. This study provides an insight about how big data, such as the NID database, can provide actionable information for community resilience toward a safer and more sustainable environment.

The rapid spread of COVID-19 has damaged the economy in the United States. To understand the resilience capacities of local businesses, we visualized the spatiotemporal patterns of permanently closed Points of Interest (POIs) after the outbreak of the pandemic. The results show that the counties with more business closures are also the counties with a larger population. The permanent closures of most local businesses occurred immediately after the lift of stay-at-home order. We also found that those business owners, who permanently shut down their businesses, may not open new ones elsewhere. In addition, the permanent closures of entertainment and recreation businesses are significantly less than that of retail and trade businesses and food services.

A Current

In this chapter, the authors examine what they call “alma mater” school shootings - those in which a current or former student returns to attack people at the school. In this case, the focus is on K-12 school shootings in the United States between 1990 and 2018 where two or more individuals were killed. They argue that many shooters target their alma mater because it is the place where they have experienced “place trauma” - emotional pain that is intertwined with a location. After discerning common demographic, personal, and spatiotemporal patterns, they discuss how the shooters acquired the firearms used to carry out the attack. Finally, the authors outline policy and practice considerations focusing on education, school funding, and legislation.
