Why are “ghost forests” filled with dead trees expanding along the mid-Atlantic and southern New England coast? Higher groundwater levels linked to sea-level rise and increased flooding from storm surges and very high tides are likely the most important factors, according to a Rutgers study on the impacts of climate change that suggests how to enhance land-use planning.
When people think of sea level rise, they usually think of coastal erosion. However, recent computer modeling studies indicate that coastal wastewater infrastructure, which includes sewer lines and cesspools, is likely to flood with groundwater as sea-level rises.
Insurance policy premiums from the National Flood Insurance Program (NFIP) allow policyholders to maintain a lower, grandfathered rate even when the risk escalates. But as coastal flooding increases due to rising sea level and more intense storms, new research published in the journal Risk Analysis suggests this grandfathered policy could lead to big losses for the NFIP. A team of experts led by Carolyn Kousky, executive director of the University of Pennsylvania’s Wharton Risk Management and Decision Processes Center, studied the effect of sea level rise on a New York City neighborhood to illustrate how grandfathered rates could impact both policyholder premiums and program revenue for the NFIP over the next 30 years. Their results project losses to the NFIP as flood risk grows in the coming decades.

Phosphorous, calcium and charcoal in spotty patches of fertile soil in the Amazon rainforest suggest that natural processes such as fires and river flooding, not the ingenuity of indigenous populations, created rare sites suitable for agriculture, according to new research.
Research co-authored by University of California scientists has found that by 2050, as many as 24,500 affordable housing units in the United States are projected to be exposed to coastal flooding.
Superstorm Sandy brought flood-levels to the New York region that had not been seen in generations.
Thunderstorms are weather disturbances characterized by concentrations of thunder, lightning and fierce winds.
DHS S&T released “Low Cost Flood Sensors: Urban Installation Guidebook” to do just that—help communities deploy and operate low cost sensors for flood monitoring and management.
The Department of Homeland Security (DHS) Science and Technology Directorate (S&T) has awarded $950,000 to develop a community-oriented, flood hazard modeling process.
Earth's tropics are expanding poleward and that expansion is driven by human-caused changes to the ocean, according to new research.
In flood-prone areas of the Hudson River valley in New York state, census areas with more white and affluent home owners tend to file a higher percentage of flood insurance claims than lower-income, minority residents, according to a new study.
When a hurricane approaches, providing a few extra hours’ notice can be the difference between life and death. Now, Penn State researchers report that applying a machine learning technique to a group of possible storm paths could help meteorologists provide more accurate medium-term forecasts and issue timely warnings to communities in the path of these potentially deadly storms.
