The head of a team of engineering experts told a US Senate committee on Wednesday that malfeasance during construction might have been one reason for the catastrophic failure of the levees that were supposed to protect New Orleans from hurricanes.
"These levees should have been expected to perform adequately at these levels if they had been designed and constructed properly," said Raymond Seed, a professor of civil engineering at the University of California, Berkeley.
"Not just human error was involved," Seed said. "There may have been malfeasance."
Seed, whose team was funded by the National Science Foundation, did not offer hard evidence to back up his accusation. But he said after the hearing that the team had been contacted by levee workers, contractors and, in some cases, widows of contractors who told stories of protective sheet pile being driven less deeply than plans called for and corners cut in choosing soils for construction, among other problems.
His group is trying to confirm the accounts, he said, and he cautioned that even if proved, they might not be a major contributing factor in the disaster, which killed 1,000 people and left 100,000 without homes.
As experts have noted, the levee specifications may not have been adequate in the first place. In particular, pilings may not have been driven deep enough to keep them from collapsing.
But the testimony raises new concerns in the aftermath of Hurricane Katrina about the protection that New Orleans received from the 40-year US$458 million flood-control system.
The current state of repair might not protect the city from another serious storm, the engineers warned.
"Short term, without a storm, they are probably adequately safe," said Peter Nicholson, a professor of civil engineering at the University of Hawaii, who led a team of levee investigators for the American Society of Civil Engineers. "Certainly with a large storm, as we are not yet out of hurricane season, and certainly for next hurricane season, there is significant risk," Nicholson said.
A fire caused by a burst gas pipe yesterday spread to several homes and sent a fireball soaring into the sky outside Malaysia’s largest city, injuring more than 100 people. The towering inferno near a gas station in Putra Heights outside Kuala Lumpur was visible for kilometers and lasted for several hours. It happened during a public holiday as Muslims, who are the majority in Malaysia, celebrate the second day of Eid al-Fitr. National oil company Petronas said the fire started at one of its gas pipelines at 8:10am and the affected pipeline was later isolated. Disaster management officials said shutting the
US Vice President J.D. Vance on Friday accused Denmark of not having done enough to protect Greenland, when he visited the strategically placed and resource-rich Danish territory coveted by US President Donald Trump. Vance made his comment during a trip to the Pituffik Space Base in northwestern Greenland, a visit viewed by Copenhagen and Nuuk as a provocation. “Our message to Denmark is very simple: You have not done a good job by the people of Greenland,” Vance told a news conference. “You have under-invested in the people of Greenland, and you have under-invested in the security architecture of this
UNREST: The authorities in Turkey arrested 13 Turkish journalists in five days, deported a BBC correspondent and on Thursday arrested a reporter from Sweden Waving flags and chanting slogans, many hundreds of thousands of anti-government demonstrators on Saturday rallied in Istanbul, Turkey, in defence of democracy after the arrest of Istanbul Mayor Ekrem Imamoglu which sparked Turkey’s worst street unrest in more than a decade. Under a cloudless blue sky, vast crowds gathered in Maltepe on the Asian side of Turkey’s biggest city on the eve of the Eid al-Fitr celebration which started yesterday, marking the end of Ramadan. Ozgur Ozel, chairman of the main opposition Republican People’s Party (CHP), which organized the rally, said there were 2.2 million people in the crowd, but
JOINT EFFORTS: The three countries have been strengthening an alliance and pressing efforts to bolster deterrence against Beijing’s assertiveness in the South China Sea The US, Japan and the Philippines on Friday staged joint naval drills to boost crisis readiness off a disputed South China Sea shoal as a Chinese military ship kept watch from a distance. The Chinese frigate attempted to get closer to the waters, where the warships and aircraft from the three allied countries were undertaking maneuvers off the Scarborough Shoal — also known as Huangyan Island (黃岩島) and claimed by Taiwan and China — in an unsettling moment but it was warned by a Philippine frigate by radio and kept away. “There was a time when they attempted to maneuver
