VIDEO : "Delta Flume" world's biggest tsunami machine

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.

1. I really want to bring a dinghy or kayak on that
2. Looks so satisfying.
3. The start should me in a "most satysfying videos"
4. C'est pas un tsunami c'est une vague scélérate.
5. this is not a tsunami tester
6. Wow Im living in the netherlands lol, I didnt know this machine was made by us xD.
7. This is in the netherlands
8. When your so high and have nothing to do in your life you buy tickets to go watch water
9. I don't know that woman's screams can make a tsunami..
10. I want to get one to destroy my mini city
11. Satisfying!
12. Hm, at least this wave looks smaller than 5m. If you regard the people it is not much higher than one of them. so it´s maybe 2m to 2,50m.
13. Ok so here is a question, who gets the bigger wave?
    The shoreline closest to the earthquake or one further away?
    Or does it all depend on which coastline has deeper water?
    scenario;
    
    One of the canary islands suffers a massive landslide into the Atlantic,
    Who would get hit with a bigger wave?
    East coast America?(if the landslide was on the west side of the island)
    Or west Africa(if the landslide happened on the east coast of the island)
    
    Seeing as there is more water between America and the Canary islands than on the African side, would distance make much difference?
    
    Also, would africa be shielded from the wave if the landslide was in the direction of the states and vice versa?
14. I would love to see that
15. It's a beautiful project... ought to make great Random, Rogue and Regular waves .. but... It can't make a Tsunami. The wave generator (hydraulic cylinders) isn't long enough. Well, It might be long enough for a very "small" tsunami where the 10 meter depth simulates the deep ocean, and the wave encounters a shore model with a very long beach using much of the length of the Delta Flume, and the resulting wave inundating the coast is about 25 cm. Tsunamis have wave lengths, when they reach the coast, of nearly 3000 meters, and a wave period measured in minutes not seconds. If you were trying to simulate a 5 meter high tsunami inundating the coast, and you wanted it to be at least 50 cm high against the coastal model. That would be a scale of 1:10. The Tsunami would have to have a wave length of 300 meters. Fortunately the Delta Flume is 300 meters long, but it's only 10 meters deep .. so, it's sallow water all the way. (1:10) is 100 meters deep. Which is sorta OK, as Tsunamis travel as "shallow water" waves. So, If you wanted to generate a tsunami using the moving wall, which is limited in stroke to 7 meters, and you wanted a 1/10 model tsunami wave period of just five minutes (real world time) you would have to make a single cycle of the wall in 95 seconds, which is a wave about 40 times longer than the Delta Flume. While the wall probably can move very slowly, a 20 second stroke cycle might make a nice one minute tsunami .. but, they don’t come that short in the real world. Sooo… please don’t refer to the Delta Flume as a tsunami machine … unless I’m missing something here … :-)
16. so proud of my country
17. That was insanely satisfying to watch for some reason.
18. It is not the biggest by a long way
19. it's wonderful
20. it's wonderful
