Seagrass’ strong potential for curbing erosion
A new study shows how seagrass can help to protect shorelines against erosion and help to mitigate damage from rising sea level, potentially providing useful guidance for seagrass restoration efforts.
Strong winds are supersizing the ocean’s biggest waves
Strong winds are driving the ocean’s biggest waves to dizzying new heights. The University of Melbourne researchers behind the work, published April 25 in the journal Science, say the supersized waves could compound the effects of rising sea levels, leading to more frequent flooding and accelerated coastal erosion.
El Niño and our beaches; By Gary Griggs
Our beaches come and go seasonally in response to changing wave conditions. The larger and more energetic winter waves stir up the beach sand and carry it offshore, eroding the shoreline back. Six months or so later, the smaller and less energetic spring and summer waves gradually move that sand back onshore, building the beach just in time for all the summer visitors.
Can 475 ‘sand cubes’ protect Capo Beach, CA from further erosion?
An estimated 475 sand cubes — 3-by-3-foot white plastic bags filled with sand — were being stacked next to one another along the eroding Capo Beach, CA where strong waves, high tides and a rising sea level have battered the area for years.
Shore fix in Cane unlikely to last, experts say, BVI
About a month ago, excavations began along the beach in the north end of Cane Garden Bay as part of a government project designed to protect a shoreline that slips further into the sea with each heavy swell. But two United States experts said that the method being used — stone-filled wire cages known as gabion baskets — probably won’t last long.
Argentina: The Atlantic Coast loses two meters of beach per year
It happens in the main beaches of Buenos Aires, due to the erosion, generated by the loss of dunes, urban intervention, with walls of cement, coastal roads, the afforestation of the dunes and the theft of sand for constructions.
Tree recycling program to help Island beaches
Recycling doesn’t have to be a beach, but in this case, it’s going to protect one. The City of Harlingen is requesting residents dispose of their Christmas trees, where they will be deployed along the dunes to prevent erosion of beach sand.
After a Long Boom, an Uncertain Future for Big Dam Projects
The rise of wind and solar power, coupled with the increasing social, environmental and financial costs of hydropower projects, could spell the end of an era of big dams. But even anti-dam activists say it’s too early to declare the demise of large-scale hydro.
‘Washaway Beach,’ fastest-eroding place on the West Coast, cobbles together a solution
There’s a reason a quiet and desolate strip of sand here is nicknamed Washaway Beach. Coastal erosion has claimed an average of 100 feet of this shoreline every year for the last century. That makes North Cove the fastest-eroding place on the West Coast.
