Dutch scientists have created the world’s biggest human-made wave generator. The Delta Flume can send waves 5 meters high, crashing down a 300-meter long, 9.5-meter deep channel. The monster machine wasn't designed to help surfers catch bigger waves, but to enhance safety against floods in the Netherlands, where half of the country’s population lives below sea level on reclaimed land.
It took Dutch engineers three years to build the Delta Flume. Waves this big haven’t been generated anywhere else in the world, researchers said.
This is how it works: Four powerful pistons behind a seven-meter high metal shield push 9 million liters of freshwater down the channel at a speed of 1,000 liters a second. The challenge is to simulate the power of the oceans. It's possible not only to generate high waves, but to simulate variations in the water level of the kind caused by storm surges and tides. According to researchers, it's important for studies of dike revetments.
