There are a lot of logistical problems that pop up when you build a 600-foot structure like the Three Gorges Dam in China’s Hubei province. For example, how do ships navigate the sudden extreme difference in water heights on either side of the dam? That’s an easy one. You just build the world’s largest elevator…
Iranian hackers gained access to the control system at the Bowman Avenue Dam in 2013. The dam is some twenty miles from New York City, according to The Wall Street Journal. Yikes.
Las Vegas gets 90 percent of its water from Lake Mead, the lake created by the Hoover Dam about 45 miles away. It’s also a lake that’s only half full—with water levels that are decreasing every year. Now the city must dig a massive tunnel that will dip deeper into the lake to ensure Las Vegas’s water supply doesn’t…
This week, for the first time in decades, the Colorado River flowed to its natural end in the Gulf of California. But it was the opposite of a natural event. The artificially engineered "pulse flow" that pushed the waters all the way to the Gulf required an unprecedented collaboration between the U.S. and Mexico,…
There's not much in rural Washington, but there are lot of dams. And dams mean hydroelectric power. Following the lure of cheap electricity, Bitcoin miners and their power-hungry server farms are making out for sleepy little towns in the Pacific Northwest.
Imagine you're a river herring, maybe about a foot long, swimming merrily upstream when you suddenly hit a giant concrete wall. How do you cross it? Engineers are now designing new fishways disguised as broad, rocky pools that help migrating fish make their way through dammed up rivers.
The floods in Colorado are being described as "Biblical," and for once that word seems to fit. Boulder, for example, usually gets around 15 inches of precipitation annually. This year, that amount has fallen in the ten days since September 9 alone. On September 12, they received nine inches in one day.
When Tsar Peter the Great founded the former Russian capital city of Saint Petersburg more than 300 years ago, he intended it to provide a "window on the Baltic." Turns out, that window was more of a screen door. To protect itself, the city built a dam that took almost 300 years and $3.85 billion to complete.
In an effort to return Washington's White Salmon River to local wildlife, engineers blew a hole in the long-standing Condit Dam. Explains photographer Andy Maser, who shot this dramatic detonation:
California's Matilija Dam is a huge mistake. Over 60 years after its construction, engineers and ecologists are realizing it does more harm than good—a feeling shared by the rogue artists who painted huge, easy instructions as a fix.
The Three Gorges dam on China's Yangtze River, pictured here, is one of the world's great engineering marvels. It's just one of many structures people have built to transform and contain China's massive rivers for the past 2,400 years.
The U.S. Bureau of Reclamation is shooting down a key legislative talking point: that the internet "kill-switch" legislation is needed to prevent cyberterrorists from opening the Hoover Dam's floodgates.
Canada's mighty beavers have been keeping busy. This newly discovered beaver dam, in Alberta's Wood Buffalo National Park, is so big it can be seen from space. Check out some more pics of the 2,788-foot marvel.
No, these aren't tunnels to alternate universes, or a path to your Sideways life: these are spillways, designed to prevent dam erosion.
