Using one of the world’s most powerful supercomputers—Titan, the 27-petaflop Cray XK7 at the Oak Ridge Leadership Computing Facility (OLCF)—a University of Iowa team performed one of the first highly resolved, 3-D, volume-of-fluid Reynolds-averaged Navier–Stokes (RANS) simulations of a dam break in a natural environment. The simulation allowed the team to map precise water levels for actual flood events over time.
DHS S&T has a solution for stopping flooding in subway tunnels in the form of a giant inflatable plug that will seal them off and stop water from flowing throughout the subway system into stations and other subway lines.
By improving visualization of weather data and information, an Emergency Manager can review the various data sources more efficiently, and HV-X gives emergency managers more tools and capabilities to support their recommendations and decision making.
Research out of the University of New Hampshire has found that some roads, as far as two miles from the shore, are facing a new hazard that currently cannot be seen by drivers - rising groundwater caused by increasing ocean water levels.
The roundtable gathered information from a diverse group of flood experts and practitioners to identify decision support tools, research and development investments and data solutions that would help meet the Flood Apex’s program objective of reducing uninsured losses.
Social media can warn us about extreme weather events before they happen – such as hurricanes, storms and floods – according to new research by the University of Warwick.
Better storm surge prediction capabilities could help reduce the impacts of extreme weather events, such as hurricanes.
Much of the flood-inducing rainfall that has pummeled California over the last month flowed into the region via a river in the sky. But these so-called atmospheric rivers, which transport large quantities of water vapor poleward from the tropics, can wreak havoc in the Southeast as well.
Irvine, Calif., Feb. 21, 2017 – Global climate change is being felt in many coastal communities of the United States, not always in the form of big weather disasters but as a steady drip, drip, drip of nuisance flooding.According to researchers at the University of California, Irvine, rising sea levels will cause these smaller events to become increasingly frequent in the future, and the cumulative effect will be comparable to extreme events such as Hurricane Katrina or Superstorm Sandy.
Virginia Tech expert says the danger at Oroville Dam in California is confined to the spillway. While forecasters expect additional storms into next week, damage to the dam itself is highly unlikely.
Sea level in the Northeast and in some other U.S. regions will rise significantly faster than the global average, according to a report released by the National Oceanic and Atmospheric Administration (NOAA). Moreover, in a worst-case scenario, global sea level could rise by about 8 feet by 2100. Robert E. Kopp, an associate professor in the Department of Earth and Planetary Sciences at Rutgers University, coauthored the report, which lays out six scenarios intended to inform national and regional planning.
A University of Iowa study finds the threat of flooding is growing in the northern half of the United States and declining in the South. The findings are based on water-height measurements at 2,042 stream and rivers, compared to NASA data showing the amount of water stored in the ground.
Intense storms have become more frequent and longer-lasting in the Great Plains and Midwest in the last 35 years. What has fueled these storms? The temperature difference between the Southern Great Plains and the Atlantic Ocean produces winds that carry moisture from the Gulf of Mexico to the Great Plains, according to a new study in Nature Communications.
Gonzaga-in-Florence, Gonzaga University’s flagship study abroad program begun here in 1963, will mark the 50th anniversary of the devastating flooding of the Arno River on Nov. 4, 1966, one of the worst in Florence history, with a special exhibition opening at 6 p.m., Wednesday, Nov. 16 in the Mozilo Center
The nation is poised to make major advances in "water intelligence" with more detailed forecasts of floods, streamflow, and potential drought conditions, a panel of experts said at a congressional briefing today.
A Southeastern Louisiana University wetlands expert and graduate student are implementing a pilot project in an eight-acre pond to determine the feasibility of floating marshlands serving as a filter to clean ponds and other small bodies of water.
"Taking Chances: The Coast After Hurricane Sandy" investigates whether Sandy was “a transformational event, just another storm or something in between.” Topics include the meteorology and climatology of Sandy, efforts to “Restore the Shore,” and impacts on water, wastewater and electrical utilities.
Texas legislators are investigating the benefits of RAPIDO, a pilot program developed with recommendations from Texas A&M University’s Hazard Reduction and Recovery Center (HRRC), that dramatically reduces the time it takes to rebuild homes destroyed by natural disasters.
NDSU faculty and students conduct world-class research, searching for answers to important questions. In a recent study, NDSU researchers explored how major floods affect the growth and development of unborn children.
Coastal Risk Consulting, a new start-up company formed by an FAU professor, has developed novel technology to assist coastal homeowners, businesses, and government to evaluate and mitigate risks from encroaching seas along Florida’s southeast coast as well as other vulnerable areas in the United States and overseas.
Effective warnings are a growing need as expanding global populations confront a wide range of hazards, such as a hurricane, wildfire, toxic chemical spill or any other environmental hazard threatens safety.
Deliberately flooding riverbeds left parched by dams has great potential to restore wetlands, but may also have a significant unintended consequence: the release of greenhouse gases.
Just how global warming is making storms more destructive has been established by Australian researchers.
The contents of historic coastal landfill sites could pose a significant environmental threat if they erode, according to a new study from Queen Mary University of London (QMUL).
Just as parts of South Florida are bracing for potential risks of flooding in low-lying areas due to the close proximity of the moon, high tides, sea-level rise and inclement weather, FAU is bringing together professionals from the private and public sectors to help identify solutions and develop adaptation pathways.
While Florida and Alaska are on the opposite ends of the spectrum, they share mutual concerns of the imminent challenges presented by environmental changes. The rapid melting of the Arctic ice is threatening coastal locations globally, and impacts include increased flooding from sea-level rise in Florida to infrastructure instability from permafrost melting in Alaska.
A study has shown that strategic planting of trees on floodplains, could reduce the height of flooding in towns downstream by up to 20 per cent.
The Earth Scan Lab has developed the most complete and cloud-free time sequence collected during a major flood event of the Mississippi River.
Flood risk can be higher with levees than without them.
Why was the New Year's flood in Missouri so bad? Most news reports blamed it on the heavy rain, but Robert Criss, PhD, professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis says analysis of the flood data shows much of the damage was due to recent modifications to the river.
