By a process of elimination, the researchers concluded that only 26 percent of the oil had come ashore or was still in the water in a form that could, in principle, do additional shoreline damage.
This study evaluates the validity of these assumptions by merging results from 689 surveys of waterfront-property owners in NC with empirical shoreline damage data collected along estuarine shorelines after Hurricanes Irene (2011) and Arthur (2014).
"Its published oil spill response plan gives no guarantee that an oil spill in the Bight would not reach the shoreline and damage the environment," Hopkins said.
At Beaufort on the Outer Banks, several structures along the shoreline experienced damage, and several under construction ships were wrecked.
Within 500 m from the shoreline, wood structure damage shows significant sensitivity to the aleatory uncertainty of the tsunami generation from the CSZ event.
Studies carried out by the engineers AS Atkins, for Tidal Electric, have suggested that the lagoons could generate twice as much power, per square mile impounded, than the barrage, and therefore generate about 25-40% more energy without damaging the shoreline.
Since the flow of oil was stopped with a cap on July 15, people on the Gulf Coast have been wondering if another shoe was going to drop — a huge underwater glob of oil emerging to damage more shorelines, for instance.
In his gloomiest assessment so far, Adm. Thad Allen of the Coast Guard, who is leading the federal response, conceded on Monday that the breadth and complexity of the spill had defied all expectations and that years of work would be required to repair the damage to shorelines, marshes and wildlife.
Shore erosion is currently causing millions of dollars worth of damage to shorelines and public properties not only along the east coast of Korea but also around the world.
Flooding also damaged shorelines along New Zealand's North Island and on Chatham Island.
It was a measure of the storm's devastation in the region that in Connecticut, where officials on Tuesday reported almost 600,000 utility customers without power, and substantial damage to many shoreline communities, the general sense was that it could have been worse.
