The National Science Foundation is funding a $13.9 million program led by the University of Alaska Fairbanks to help multiple communities respond to coastal erosion, flooding, permafrost thaw and other hazards attributed to climate change.

A renowned oceanographer who has studied the California coast for decades says new research challenges a well-established notion about how sand flows within the surf and long-shore currents that constantly shape the state's beaches.

Louisiana has been allowed by the Army Corps of Engineers to count $110 million spent on two major coastal restoration projects in recent years as credits towards the state’s $1.12 billion share of the cost of the $14.6 billion post-Katrina New Orleans area hurricane levee system.

UNION BEACH, N.J. -- There's a race against time and rising sea levels in Union Beach, New Jersey. Typically, water wins.

BREVARD COUNTY, Fla. — Nearly $50 million of federal funding will go into replacing sand on the beaches of Brevard County after being hit by Hurricane Ian, then Nicole.

The legislation offers a roadmap for working with, rather than against, Mother Nature when it comes to protecting the NY coastline.

Enter Erosion Mitigation Units, or EMUs, a cutting-edge approach to coastal defence that offers both protection and environmental benefits.

The bayside town that became the poster child for some of the most severe devastation wrought by Hurricane Sandy in 2012 is making progress on a $395 million federal project that’s been in the works even longer than that.

Additional sand nourishment and the utilization of artificial retention devices highlighted some of the solutions suggested to rescue critically vulnerable San Clemente beaches at a community meeting on Sept. 27.

Jordan Kelly, Brand manager at Oceans, says: “Ocean warming might sound distant to many of us, but the effects this can have on locations much closer to home can be detrimental.

The federal agency that will oversee a major beach replenishment project this fall or winter for Ocean City, Sea Isle City and Strathmere is considering its options after bids for the contract came in significantly higher than the government’s estimate.

"Installation of the future" includes strengthened envelope and elevation requirements, coastal resilience

JINHUA, China — In the shade of a willow tree, Li Tao and his buddy dabble lines in a slow-moving river channel and occasionally pull out a tiny fish. "It's good to have a place like this for people to relax," says Li, his shirt off in the midday heat. This place — called Baisha Creek — has come full circle.

White blankets of sand, bright blue water and palm trees swaying with the breeze – it’s the picturesque landscape that comes to mind when you think of Florida’s beaches. But this stunning scenery comes at a cost with the need to regularly artificially replenish eroding shorelines, a process also known as beach nourishment.

The river model was instrumental in charting the potential impacts of the Mid-Barataria Sediment Diversion Project, which broke ground in August.

(CNN) — Hurricanes, heat and humidity have always been looming threats on the Gulf Coast. But as drought grows in the Central US and sea level rises, residents in southern Louisiana are finding a formerly unusual emergency is becoming more frequent: saltwater is infecting drinking water city by city up the Mississippi River.

Inflation could push the cost of Texas' coastal barrier project — already expected to be the largest civil engineering project in U.S. history — to $57 billion, the U.S. Army Corps of Engineers said.

A little-known climate threat lurks under our feet: rising groundwater that could release toxic chemicals from more than 132,000 contaminated sites in coastal areas of the US. In a first of its kind study, researchers estimated the number of polluted industrial sites and mapped them to areas likely to experience groundwater inundation due to rising seas.

County officials estimate they've lost almost 50,000 cubic yards worth of sand in places like Coquina Beach.

Sea-level rise is often pointed to as the unbeatable culprit chomping away at Southern California's most popular asset. But rising seas aren't the only reason the coastline is disappearing. Decades of development along the coast blocked sand flow to beaches.

Pinellas County officials are taking emergency measures to shore up some beaches that were slammed by Hurricane Idalia. It will be paid for with money from county tourist development taxes.

Thomas K. Ruppert, a coastal planning specialist with Florida Sea Grant and thought leader on legal policy around sea-level rise adaptation and other areas of environmental law, has been selected as the assistant provost for coastal resilience and director of the new Virginia Coastal Resilience Collaborative (VCRC) at William & Mary.

Potential health risks of high salt concentrations for those who rely on Mississippi River lead mayor to sign declaration

Coastlines – the interface between land and sea – lie at the frontline in the battle against climate change impacts.

STATEN ISLAND, N.Y. — Staten Island’s “Living Breakwaters” project received international acclaim this month as the winner of the 2023 Obel award, which recognizes outstanding architectural contributions in service of both people and the planet.
