Скачать или смотреть The $240M Race to Save A 130-Year-Old Wall in The Ocean

At the mouth of the Columbia River, where the powerful Pacific Ocean meets one of North America’s mightiest waterways, stands a 130-year-old engineering marvel—the Columbia River Jetty system. This 9.7-mile-long stone barrier has protected ships from treacherous waves, ensuring that nearly $20 billion worth of trade flows through each year. Without it, navigating this passage would be nearly impossible for 7 to 8 months annually!

But now, the wall is breaking down—and if a single section collapses, it could choke one of the busiest trade routes in the U.S. The stakes couldn’t be higher. In this video, we dive into the mind-blowing engineering challenges behind the jetty’s construction, the massive repair efforts currently underway, and the cutting-edge technology used to reinforce this critical structure.

From 40-foot-tall deadly waves to custom-built excavators and GPS-guided boulder placements, this is a story of resilience, human ingenuity, and a race against time. But with storms intensifying and sea levels rising, is traditional jetty repair enough? We explore alternative solutions from around the world, including London’s Thames Barrier and Venice’s Mose Project—could these innovations offer a better way to protect this vital gateway?
