New Orleans As the season of the Atlantic Ocean It has startedA new study published by researchers at the University of Toulin reveals the hot points in the walls of the concrete floods of the New Orleans, which were reinforced in the aftermath of this Hurricane Katrina.
The study found that the walls of concrete floods in the city are sinking faster than high levels of sea surface, which reduces the ability to prevent storm storms in some neighborhoods.
“There is certainly a possibility in the future, if these rates continue, to reduce the level of protection of the flood protection system,” Professor Tolin Mid Alison, a study author, told CBS News.
This summer represents 20 years since Katrina fell on the Gulf coast, leaving more than 1300 dead people And the displacement of more than a million people throughout the region.
After the destroyed storm, $ 15 billion was spent to strengthen the water -designed tax system. New Orleans, many of which lies below sea level, depends on this elaborate system of dams, pumps and drainage channels.
The study, published in the Journal of Science Advances, used satellite radar data to track transformations in the ground height across the Greater New Orleans between 2002 and 2020.
“In a city like New Orleans, where many land are already near sea level, it can increase the risk of simple floods,” said Simon Fexi – the author of the study and former researcher in Tolins. Department of Science and Coastal Engineering RiverIt works now in Tre-ALTAMIRA- in a statement.
“These results are an invitation to wake up,” Alison said. “We need continuous monitoring and maintenance to ensure that our flood defenses do not lose their level of protection under it.”
If trends persist, and the infrastructure is left without deterrence, the study found that wetlands east of the city can convert the swamps into open water during the next ten years if the trends continue – which leads to the disposal of temporary stores of the high critical storms to the Louisiana coast.
The study also identified some of the possible causes of sunken hot points. It found that the pockets of land drowned around industrial sites, Luis Armstrong New Orleans International Airport, and the latest residential developments – areas that are likely to be soil pressure and underground water.
The researchers said the results also emphasize some possible solutions to protect New Orleans and other coastal societies around the world, including repeated promotions of the flood protection and satellite control system.
Some residents who live in the Mishoud neighborhood on the eastern side of the city – one of the areas that have been identified in the study as drowning more quickly than others – are concerned that priority is not given to maintenance. SYNTHIA Viltus, residing in Michood, indicated that drilling and other smaller infrastructure issues in its neighborhood have been unlawful for months.
“I have any belief in the state’s federal leaders to maintain the update of the fees,” said Feltos.
The study found positive – some areas where industrial activities stopped have already caused the lifting of the land.
The authors of the study also hope that their work will help direct other coastal cities that may face similar challenges for New Orleans.
“This research indicates that the movement of land is not uniform, and understanding these patterns is crucial to protecting lives and property in a really important inch city,” Festy said in the statement. “However, it is important to remember that our results still require a precise filtration. This is especially true for critical areas such as flood walls, as checking on the site was not possible during this project.”
When CBS News reached it, the US Army Engineers Corps said the fees were designed to last for at least 25 years. Usace added that he is already in the process of upgrading the fees so that they can continue for another 50 years.
