Excerpts;

Coastal erosion may release waste from ten per cent of England’s historic coastal landfills in the next forty years, according to research from Queen Mary University of London and the Environment Agency.

There are at least 1,215 historic coastal landfill sites in England, mostly clustered around estuaries with major cities, including Liverpool, London, and Newcastle on Tyne. An investigation by researchers finds that 122 sites are at risk of starting to erode into coastal waters by 2055 if not adequately protected…

While a new island grew, southern Hatteras was shrinking, NC


The waters off of North Carolina’s barrier islands have been called a “graveyard of the Atlantic.” Countless ships have wrecked here, due to the area’s treacherous weather and currents and its expansive shoals. These shoals are, by definition, usually submerged. But occasionally parts of them can rise above sea level.
These natural-color images, acquired by the Operational Land Imager (OLI) on the Landsat 8 satellite, show the shoal area off of Cape Point at Cape Hatteras National Seashore—the site of a newly exposed shoal nicknamed “Shelly Island.” The first image was captured in November 2016. When the second image was acquired in January 2017, waves were clearly breaking on the shallow region off the cape’s tip. The site of those breakers is where the island eventually formed, visible in the third image captured in July 2017. The new island measures about a mile long.

The largest dam-removal project in U.S. history—the Elwha River Restoration Project—commenced during the second week of September 2011, when National Park Service contractors began to dismantle two dams on the Elwha River in Washington State. The 32-m-tall Elwha Dam and the 64-m-tall Glines Canyon Dam, completed in 1913 and 1927, respectively, have been blocking the natural supply of sediment to the lower river and coast and severely limiting salmon and steelhead spawning for nearly a century.

Surfers’ Point appears to be a rare natural California oceanfront. But looks deceive.

The beach is man-made. It was built the length of five football fields with an 8-foot-thick layer of cobblestones topped with enough imported sand to fill nearly 2,000 dump trucks.

The city of Ventura and environmental groups like the Surfrider Foundation launched the $4 million beach-building project when the coastline eroded in the early 1990s because the Ventura River was no longer bringing enough sand and sediment to nourish the beach.

Many Texas Beaches Likely to Erode, Be Overwashed, or Inundated by Hurricane Harvey


This is a screenshot of the USGS Coastal Change Hazards Portal, which shows current coastal impact projections for Hurricane Harvey.

By USGS;

New projections from the U.S. Geological Survey indicate Hurricane Harvey is likely to cause significant beach erosion along the Texas coastline, with water overtopping dunes and in some cases inundating areas.

As of Friday morning, the USGS Coastal Change Forecast model is predicting that 94 percent of Texas’s 367 miles of coastline will undergo some level of beach erosion from the storm surge and large waves Hurricane Harvey will produce.

“Significant coastal erosion along the coastline of Texas is expected due to the rapid strengthening of Hurricane Harvey,” said Joseph Long, USGS Research Oceanographer. “While the forecasts are subject to change as Harvey approaches land, we are making these forecasts to help inform emergency managers and communities on the potential coastal erosion hazards to be prepared for during the storm.”

There are many factors and variables to consider when trying to determine what a large storm like Harvey might do to the coast. The USGS Coastal Change Forecast model uses the National Hurricane Center’s storm surge predictions and National Oceanic and Atmospheric Administration wave forecast models as key inputs, and adds information about the beach slope and dune height to predict how high waves and surge will move up the beach and whether the protective dunes will be overtopped.

Results of the modeling indicate Hurricane Harvey could have a significant impact on the beaches and dunes coastal Texas.

The Coastal Change Forecast model is also projecting that 47 percent of Texas’s coastline will experience a more severe level of erosion hazard, known as dune overwash, particularly north of Corpus Christi up to the Galveston area. As waves and surge reach higher than the top of a dune, overwash occurs, often transporting large amounts of sand across coastal environments and roadways, depositing sand inland and causing significant changes to the landscape and possibly impeding transportation routes.

Inundation is the most severe level of coastal damage from a storm and occurs when beaches and dunes are completely and continuously submerged by surge. Currently, 14 percent of Texas’s coastline is projected to experience inundation in areas north of Corpus Christi to the Galveston area.

“The public should understand that whenever we have almost 100 percent of a coastline expected to experience erosion and a large portion of it projected to have dune overwash and inundation, that it is a very hazardous condition and that the beaches will look dramatically different after the storm passes,” Long said.

A map of these estimates can be viewed on the USGS’ Coastal Change Hazards Portal, which is easily accessible to the public. The coastal change forecast can be used by emergency managers to help identify locations where coastal impacts might be the most severe, such as where roads may be damaged or covered by sand and impassable even after the storm is over.

While the final projections for Hurricane Harvey will continue to change, Harvey is forecasted to remain a powerful storm for several days and to bring damaging conditions to Texas and possibly other gulf coast states beaches as well.

Zeebrugge, Belgium


Astronaut photograph ISS051-E-13055 was acquired on April 13, 2017.

By Justin Wilkinson, Texas State University, JETS Contract at NASA-JSC;

Looking down on the narrow seas between Europe and England, an astronaut took this photograph of the small town of Zeebrugge, one of Europe’s most important modern ports. This Belgian town has just 4,000 inhabitants, but it takes 11,000 people to operate the port, so workers stream in from neighboring coastal towns such as Knokke-Heist, Heist-aan-Zee, and Blankenberge.

Zeebrugge is a town of superlatives. It is the world’s largest port for the import and export of new vehicles, with more than 1.6 million handled in 2010. Zeebrugge is also the site of Europe’s largest liquid natural gas (LNG) terminal, receiving the gas via an undersea pipeline from the North Sea.

The port at Zeebrugge accommodates “ultra-large” container ships, so it is one of the most important European hubs for containerized cargo. The most important function of the port is intense “RoRo traffic” (roll-on roll-off) between cities on the Continent, Great Britain, Scandinavia, and Southern Europe. The port handles more than 2.5 million standard containers (TEUs) and 50 million tonnes of cargo each year.

Being close to the United Kingdom, the coastal town also functions as a passenger ferry terminal. It attracts tourists to its cruise ships as well as its beaches, which are well developed north of the harbor in Albertstrand. Zeebrugge is also Belgium’s most important fishing port, and its wholesale fish market is one of the largest in Europe.

Hundreds of years ago, an arm of the sea extended well inland as far as the village of Damme, which acted as a port for centuries. When this inlet silted up, Zeebrugge became the port for the famous historical inland city of Bruges (just outside the lower right of the photo) with which it is still connected by a straight canal. Zeebrugge means Bruges by the sea.
