• SECURITY OFFICERSSecurity Officers: Occupational Employment and Wages

    There are more than 1.1 million security officers in the United States, and they form an essential part of the U.S. economy, playing an important role in maintaining safety and security across various sectors. The wages of security officers in the United States vary depending on several factors such as location, experience, and the specific industry they are employed in.

  • DAMSUsing AI to Help Dams Run Smarter

    Korea faces a precipitation peak during the summer, relying on dams and associated infrastructure for water management. However, the escalating global climate crisis has led to the emergence of unforeseen typhoons and droughts, complicating dam operations. In response, a new study has emerged, aiming to surpass conventional physical models by harnessing the potential of an artificial intelligence (AI) model trained on extensive big data.

  • ENERGY SECURITYNon-powered Dams Offer Opportunity for Clean Energy

    The era of building big dams may be over in the United States, but hydroelectricity still has a significant and untapped role to play in the nation’s energy future. Trouble is, 97 percent of U.S. dams don’t make electricity. A new tool could help tap that resource.

  • DAMSDeadly Dam Failures: Cause, Effect, and Prevention

    By Zulfikar Abbany

    No dam is flood-proof. Thousands are at alert level. But dam failure needn’t be deadly the way it was in Libya’s devastating floods. Here’s what you need to know.

  • FLOODSHow Well-Managed Dams and Smart Forecasting Can Limit Flooding as Extreme Storms Become More Common in a Warming World

    By Riley Post

    The United States is home to over 50,000 operable reservoirs that are overseen by dozens of state and federal agencies. As rising global temperatures make extreme storms more common, the nation’s dams and reservoirs – crucial to keeping communities dry – are being tested.

  • DAMSClimate Change Is Increasing Stress on Thousands of Aging Dams Across the U.S.

    By Hiba Baroud

    There are more than 91,000 dams across the U.S., in all 50 states, with diverse designs and purposes. The average dam age is 60 years, and more than 8,000 dams are over 90 years old. The American Society of Civil Engineers’ report card for the nation’s infrastructure gave U.S. dams a “D” grade.

  • DAMSSupporting Dams with Innovative Materials

    There are about 91,000 dams in the United States. About half the dams built in the past century and a half are starting to show their age, with resulting wear and tear. Severe weather events, extreme temperatures, erosion and rising water levels are all straining the infrastructure and exacerbating the impacts of deterioration and aging processes. In many cases, simply replacing the dams and levees is not a viable option due to high costs.

  • DAM SAFETYProbable Maximum Flood Events Will Significantly Increase Over Next Decades

    The flood capacity of dams could be at greater risk of being exceeded due to out-of-date modelling for potential maximum rainfall. A new study concludes that the rainfall model that engineers use to help design critical infrastructure such as large dams and nuclear power plants need to be updated to account for climate change.

  • DAM EMERGENCIESPreparing Communities for Dam-Related Emergencies

    There are more than 90,000 dams registered in the U.S. National Inventory of Dams across the country. But we rarely hear about them until the worst happens: one of them fails. Extreme weather events and the aging dam infrastructure are making dam-related emergency action plans more critical than ever.

  • WATER SECURITYDoes Drought-Prone California Need Another Reservoir?

    By Felicity Barringer

    For a century, California and the West have grappled with the job of storing water. The first half of the 20th century was the heyday of western dams; now many of them are aging; they were designed for the needs and values of another era. Is California “dammed out?” Or could increasing reservoir capacity help the state ride out the new era of aridification?

  • DAMSFEMA Funding Opportunities for Dam Safety

    There are 90,000 dams in the United States, many of them old and poorly maintained. FEMA will commit $33 million for two funding opportunities to enhance dam safety efforts across the United States.

  • DAMSClimate Change Contributor to 2017 Oroville Dam Spillway Incident

    A one-two punch of precipitation resulted in damage to Oroville Dam’s main and emergency spillways pushing the second largest dam in California into a crisis in February 2017. Researchers say that they have identified the fingerprint of climate change in the events that triggered the incident. Issues with the dam’s spillways led to the evacuation of 188,000 people.

  • DamsBipartisan Legislation Addresses Dams’ Safety, Hydropower

    There are more than 90,000 dams in the U.S., including 6,000 “high-hazard” dams with poor, unsatisfactory, or unknown safety ratings, posing threats to life and property. Hydropower is responsible for 6 percent of electricity production in the U.S.— and more than 90 percent of the U.S. current electricity storage capacity — but the dams which generate this power are aging and need upgrades.

  • DamsWater Dispute on the Nile River Could Destabilize the Region

    By Gary Polakovic

    The rapid filling of a giant dam at the source of the world’s longest river could reduce the water supplies going to Egypt and increase tensions with Ethiopia, a new study finds.

  • DamsRole of Dams in Reducing Global Flood Risks under Climate Change

    Flood is amongst the costliest natural disasters. Globally, flood risk is projected to increase in the future, driven by climate change and population growth. The role of dams in flood mitigation, previously unaccounted for, was found to decrease by approximately 15 percent the number of people globally exposed to historical once-in-100-year floods, downstream of dams during the twenty-first century.
