UCL Engineering - Tsunami defence

- The large waves created by earthquakes under the sea floor destroy thousands of lives and livelihoods each year, but we know very little about how these massive walls of water behave. Dr Tiziana Rosetto (UCL Civil, Environmental and Geomatic Engineering) and colleagues studying fluid dynamics have created a completely new way of generating models of these waves. The information they gain allows them to predict the damage exacted by tsunami on buildings and infrastructure, helping communities worldwide defend against these potential disasters.

I've got a design I've been trying to show the UCL, but they have not replied to my emails. Its a cracking design aswell.
You should build 3 walls with pumps inbetween them. The small wall will overflow. After this happening, pumps are activated with the seawater. It pumps the water 5 cm above the normal sea level back to the sea in many pipes about 10 cm average capacity. The second wall is higher than the first wall. If the speed of the water with a bigger tsunami tops the second wall even with the first battery pumps are working and overflows it, another battery of pumps is activated to pump the water back into the sea with a sewer type pipes average 1 meter. When the system is built in Japan it could be accompanied with a fourth wall with a 3rd generation battery even larger pumps. Then you are talking about large sewerpipes about 5 meter in diameter where the water is sent back to the sea to neutralize the large wave. I guess this system could prevent damage on coast line from tsunami waves approx 40 m high. You need to build 4 walls 1 Very Large wall, 1 smaller, 1 even smaller and for a small tsunami the smallest wall. This system should be tested in a small environment. Its wise to construct the walls with armoured concrete connecting the wals to eachother. This will make the tsunami defence system even stronger..
no because the price to construct this and maintain the pumps yearly will deffinantly cost more than the damage the tsunami causes. meaning you will crash your economic value of your ocean side tourism..... good idea but not plausable
Kristopher Prevo yeah put it would save lives at a higher cost
It lasts about 5 minutes to get the water level rise. If it's protected with multiple walls and alarm switches that goes off when the water goes over the first wall it would buy time to evacuate this coastline more efficiently. It would take another 5 minutes to overcome the second wall. it would buy another 10 minutes to overcome the third wall. But with pumps , activated by the same sensors, inbetween it would last even longer. It would absolutely buy more time to evacuate all residents on this coastline. Yes at a higher cost, but more human lifes saved. And human lives are worth more than all gold in the whole world.
Wim Hamhuis lol humans can be bought for less. No this still would not be enough time studies have been done it would take hours to evacuate everyone with congestion and traffic. Not to mention trillions would be spent over the course of years just for maintenance of the pumps and walls for a hypothetical tsunami to hit. This would completely drain the economy not to mention might not even work does nobody remember Katrina.... Now if for some reason they could hold the water back for a course of time now you have a greater risk on your hands if said walls were to fail the result of the already built up pressure would all at once suddenly be released causing even greater damage. You people act as if you know what would happen like you have degrees in architecture and urban planning. This has for years been a study that has constantly fail that's why most islands now have barrier island built to lessen the blow not pumps and walls and levies. Just getting the pumps would use so much energy most couldn't be powered by most powerplants as they cannot support that much current. Then you have failures and trillions lost in maintance washed away in a sweep devastating the economy and rebuild would never start again remember Katrina that was a structure failure that whipped away a city never to bounce back. Now that was just a wall.... Now add million dollar pumps and secondary walls. It would be even more lives lost in months to come due to relocation and economic rebuild. These things that you think are an easy solution would bankrupt and fail most of the time for an event that happens once in a lifetime. We have early notice and alarms to evacuate days before this would break land the ones we loose would be those who chose to stay. Darwin will take over.
Wim Hamhuis it sounds great but they would spend millions or even billions for it and a Tsunami might not even hit just saying but good idea
Instead of blocking, re-direct it
It would be good to build kind of infrastructure that prevent from the devastating effects of the waves and just arise the water like a slow river flooding, it would reduce the damages costs considerably and the lives too.
The energy of the tsunami in Japan had the equivalent to 36 times the nukes that destroyed Hiroshima and Nagasaki combined.
You would need pretty high and strong walls for that
Not necessarily, my idea is brilliant yet the UCL have not replied to my emails regarding if they'd like to see it.
All you need to do is watch all the videos of the Japan Tsunami of 3/11/2011 to see that the force of a Tsunami cannot be tamed in a one size fits all solution. Alot of Coastal Residences are too close to build a wall sufficient enough to hold back destructive waters. A 10-20ft concrete wall is unattractive for a beach front property.
I want to work for you
Yay !
These fkn things terrify me
Trump's said, WE NEED TO BUILD A WALLLLLL
...what about underground safe bunkers for civilians to run into, making them water proof. Or what if they built a massive boat facing the ocean close to the shores as high as the biggest tsunami ever recorded rather than civilians trying to out run the tsunami which they won't be able to.
Chevere4U Why does that sound extremely similar to an ark? O_o
GP9Xtreme good point. An ark. They should build an ark by the beaches. Nothing can stop water.
Chevere4U And exactly how do you plan on getting thousands of people onto these boat, in a matter of hours?
Heuu Arnesen sound the ALARM!!
Chevere4U Yeah, but what about getting the people from the shore to the boat? It would take hundreds of small boats, and all those boats has to be at the ready in a really short timespan
A massive shield should do the trick like a bubble
Spelled defense wrong
Nemo Sniper They didn’t. Their British like me so they spell it “defence” but you are American likely so you spell it “defense”
