Think about being a child on the beach, I build walls around your sandals. When you make these houses right, the waves come in and surround your kingdom, before the walls fall. By sending the rising water, you would have saved your palace – for a short time.
Now think of the big things. Imagine that you are preparing for a city in an area where you are threatened by rising sea levels and you have spent a lot of money to build a decent ocean. The waves come and the wall saves, saving billions of dollars of property damage. Comma: whipping. Like the waves that you toss around your sand, the rising water seeps into the wall and sinks to the sides. You have saved your inhabitants, but you have destroyed others.
New examples show how these catastrophic water hazards can affect the San Francisco Bay Area, where water levels rise 7 feet in the next 80 years. “This rise in water levels puts millions and billions of dollars in households at risk,” said Anne Guerry, senior vice president and senior scientist at Stanford University’s Natural Capital Project, who co-sponsored it. paper explain the research. It was published this week in a newspaper Growth of the National Academy of Science. “One of the new features of the project is that people have not yet considered how communities, such as the Bay Area, communicate with each other through these waters,” he continued.
Guerry and his colleagues adapted to break the coast into sections, mimicking the shape as geology. They then use hydrological models to show where the rising water goes if a portion of the coast is reinforced by the sea wall. In fact, they wonder what would happen if the citizens of another region could protect themselves without having to worry about the coming hydrology. “That water has to flow somewhere, ”Says Guerry. “And what we have found is that it only goes to other areas, which makes their flooding even bigger.”
He also included financial systems to calculate how much would hurt this. For example, it is thought that if the government were to cast a wall around the city of San Jose, located in South Bay, it would fill some 14,400 Olympic water reserves. San Jose would have been saved, but near Redwood City and other areas would have been fooled. “This is equivalent to $ 723 million in flood relief after the floods only in spring, when the water level is naturally high,” says Guerry. “And just starting to build one great wall of the ocean.” And the $ 700 million total does not necessarily mean harm to the environment and the fish, so the figure is stable.
Extra water pushed behind the wall of the San Jose can also be reached as far as the crossing, at Napa and Sonoma, 50 miles north. The damage would have been four ways: If the Napa and Sonoma beaches were protected, South Bay would see tens of millions of dollars in revenue.
That is not good news, considering the tendency of people to build large coastal cities, which township makers now have to deal with strengthen, and the lake is often the best protection. By 2100, the U.S. alone is expected to spend $ 300 billion on bombs to prevent rising sea levels and tidal waves, says the paper very powerful and climate change. Legislators should immediately consider whether to implement it $ 26 billion on a wall near the city of Houston. Jakarta, too, is supposed to make a huge seawall, but it can’t get to the bottom of it stop drowning.
To date, policymakers have done so he thinks The area could be detrimental to neighboring areas, but this new study shows the potential for it, says Laura Feinstein, director and resilience at SPUR, a Bay Area-based community-based for-profit organization. (He did not participate in the study.) “It is a more and more difficult demonstration of something that people have been saying about rising water, which means that parts of the world are sinking or swimming together,” he says. “If another area supports the use of the coast, this will contribute to sea level rise for its neighbors.”
