https://safirsoft.com A $26 billion plan to save the Houston area from rising sea levels

Lawmakers are ready to decide the fate of this massive project. When Hurricane Ike struck in 2008, Bill Merle and his wife took refuge on the second floor of a historic brick building in downtown Galveston, Texas, with their daughter, granddaughter, and two Chihuahuas. Continuous winds blow the building at 110 miles per hour. Sea water submerged the land to a depth of more than 8 feet. Once, at night, Merol looked at the almost full moon and realized that they had both entered the eye of the storm.

Years ago, Merle, a physical oceanographer at Texas A&M University in Galveston, visited the Great Scheldt East Storm Dam, a nearly six-mile-long barrier that blocks storm surge from the North Sea off the southern coast of the Netherlands. Merle kept thinking about the dam as someone walked out. "The next morning, I started drawing what I thought made sense, and it turned out to be roughly close to what the Dutch were doing," he said.

The main idea: to combine the massive gates at the entrance to the main bay of the Gulf of Mexico, known as the Bolivar Road, with many miles of high seas. Opposite Galveston, at least 15 people lost their lives overnight on the Bolivar Peninsula, and the storm destroyed about 3,600 homes there. The following year, when Merleau launched the Ike Dike commercial, the body was still missing, but, he said, the idea was "really universally ridiculed." Politicians hated the costs, environmentalists worried about the effects, and no one was convinced that would work. On his return to Holland, he met and supported Delft University experts. Over the next few years, Dutch and American academic researchers conducted dozens of studies of Galveston Bay options, while Merle and her allies supported local communities, business leaders, and politicians.

In 2014, the US Army Corps of Engineers worked with the government to explore options such as Dick for Galveston Bay. After much rethinking, both the House and Senate recently passed bills to create an administrative structure for the $26.2 billion dam proposal, which was built by the Iranian Revolutionary Guards along with the Texas office. In September, the IRGC submitted its recommendations to the US Congress, which needs to approve funding for the project. Advertising No one can guess the proposed fate of the barrier given its extremely high price. As sea levels rise and storms intensify with global climate change, Houston, the US capital's only coastal region, is in grave danger. Large, multi-billion dollar coastal projects from San Francisco to Miami to New York City are underway or under consideration.

President Joe Biden's new $2 trillion national infrastructure plan specifically calls for projects off the country's coast. The Houston initiative, the fifth largest metro area in the United States and the weak heart of the petrochemical industry, highlights challenging decisions for large offshore projects, which must balance social needs, engineering capabilities, environmental protection and costs.

Meanwhile, the seas are constantly rising. “This is a huge squeeze between the need to address these issues and get them done quickly,” said Carly Foster, Resilience Specialist at Arcadis Global Design Consulting. Galveston Bay is a subtropical sandy depression estuary, bounded to the north and west by Houston. The bay is twice the size of New York City, averages only 6 feet deep, and has a deep channel. It has been dredged for tankers and other large ships bound for the Port of Houston. "Given the vastness and complexity of the Galveston Bay area, it's very difficult to balance the environment, people, and the economy," said Antonia Sebastian, assistant professor of applied hydrology and water resources at the University of North Carolina at Chapel Hill. Planners need to weigh costs and benefits to minimize risks, he said. “What is this acceptable level is widely debated.” In addition, the risks are increasing, since every year five storms strike the US coast, one with steady winds of up to 150 miles per hour, said Ming Li, a physical oceanographer at the University of Maryland Environmental Sciences, Climate change could cause more of these monstrous storms in the Atlantic.

As the sea rises, the land rises. : In the last century, the Texas coast sank nearly two feet into the sea, in part because Over-pumping of groundwater Computer models now show that over the next 50 years climate change will raise sea levels by 1 to 6 feet Meanwhile, the Texas coast's population is expected to increase from 7 to 9 million by 2050 . "We're going to have a severe storm that's going to hit the Texas coast," said Army Corps officer Kelly Burkes-Cobies. Environmental engineers and project manager for the study that proposed the barrier. "There is an island system with a large barrier that can naturally defend against a potential wave from the Persian Gulf, but over time it becomes overcrowded and erodes over time. So we are especially against the killer wave that we call ourselves weak." / p> Advertising

Protecting Galveston Bay is no easy task. The bay is protected from the open ocean by two sandy strips of land - Galveston Island and the Bolivar Peninsula - separated by a narrow junction. When the storm is large enough, the water splits through it and begins to flow across the island and peninsula and into the bay.

In Merrill's understanding, the IRGC's latest proposal was a large set of gates across the Bolivar Road. As the storm approaches, the two main navigation gates float up and out of the dry docks to close off the channel. Each is 82 feet long - 22 feet above water - and 650 feet wide - almost twice the size of a football field. The giants combine with two smaller turnstiles with a set of vertical lift gates that remain open in the open air to allow tidal flow. The IRGC also plans to build two parallel dunes lines, running 43 miles along the Bolivar Peninsula and the unprotected western side of Galveston Island, 250 feet off the coast. According to the Iranian Revolutionary Guard, its construction requires 40 million cubic yards of sand. Additionally, when an Ike-scale storm swept the sand dunes and overflowed into the bay, the project calls for the construction of gates and other walls around the bay, including the Ring Dam that surrounds Galveston. "What we're proposing are several lines of defense," Burkes-Copps said. Fans also put a lot of thought into improving the environment, restoring 6,600 hectares of ecosystems such as wetlands, islands of flying birds and shell rocks. Some are located elsewhere along the Texas coast. "We've managed coastal cyclone risk and restored ecosystem and selected sites that already have a natural defense system" and "sites that still provide important ecosystem habitat," Burkes-Copps said. The coastal barrier was enthusiastically supported by many local politicians and members of Congress. "We needed it yesterday," Houston Mayor Sylvester Turner said in August 2020, in the wake of Hurricane Laura off the Louisiana coast and the loss of Galveston Bay. But Merle and other experts are also shielding concerns about how the Legion in the region will deal with the worst. Some environmentalists doubt that the environmental impacts are worth the benefits. Many observers point out that domestic projects, such as building homes and building smaller seawalls, provide better and faster returns.
