Not all of them. Some do more damage than harm when you consider the whole coastline. Some just shunt the erosion down the coast while others make the erosion worse where they are.
the cool thing i find about thia video is that you can clearly see how the coastal defences work and how effective they are, but in class, you learn about WHY even the most effective defences arent always used. despite that i remember hating when i had to write 8 markers about the social, cultural and economical(?) impacts 😭
The problem is beaches EXIST because of erosion. A sea wall may have stopped the beach eroding, but now you've essentially just turned it into reclaimed land. Given time plants would start to colonise the sand, forming first dunes, and eventually a meadow. That is if some developer didn't see it first and go "What a great site to build sea front property on!"
Well, that’s sort of the point. It isn’t a problem, it’s by design (not that Batman seems to know it). What’s really interesting is that you can actually see a sandy beach form during the first and second tests.
I prefer glass, concrete, and refined metals over plants and dunes. Gross, when I look at nature, I see an opportunity to remove those pesky things like wildlife, plants, and natural landscapes to build a nice Walmart, fast food chains, and weed shops. As well as casinos and brothels. All on top a think layer of asphalt, not a blade of grass in sight.
Would love to see these "gray infrastructure" solutions compared with green infrastructure - salt marshes, mangroves, oyster reefs - the natural systems that are actually cost-effective for long-term coastal resilience, especially facing sea-level rise.
for the hollow break water, you need to alternate the beams. like for the gap in the front there needs to be no gap in the back or at least no gap directly behind, breakwaters are cheaper to make if hollow so i hope you implement this change in the future. . this way you can dissipate the energy better.
Although this seems very straightforward watching it here, I can't help but wonder the bright mind that come up with these ideas and implement them in real life. Engineering is amazing.
Thanks for this! I am going to do this with my students as our end of year project give the kids a bag of LEGOs and/or other building materials if I don't have enough for 35 groups.
This sea wall design ive seen is very different to ones ive come across. They normally combine the last two to create a wall that has the shape of a curve, and it looks like a crashing wave. Its strong, secure, and the curve stops water going over. Although its considered by many pretty ugly
I actually did this experiment myself with my own lego technics pieces. However mine was done in a 120 gallon tank and included a very intricate lego avatar build (which I had made custom). Good to know that great builders think alike. Brick on, my lego friend.
i feel like the ones that left holes in the bottom were a huge risk of sinkhole if the sand decides it isn’t feeling very gravitationally stable that day
Nice video, just wild im writing my bachelor exam in civil engineering on this topic and the algorithm shows me this. We did physical model tests in a 3d wave basin to test the effect of different tipes on wave overtopping. To predict overtopping for föhr a small island in the North sea. We used a vertical wall behind a promenade, and a vertical wall with a wave return wall. The wave return wall (/bulnose) did reduce the average overtopping rate at least 70% along the shoreline.
I'd also like to see how a non-sand-only beach would work. Most natural beaches aren't just sand or rock, but also quite a lot of beach grass that reinforces the sediment and reduces erosion overall. I wonder how you'd reproduce that with lego pieces...
Thanks for the last statement because I was continuously thinking that erosion will win in the end it always wins because it has time, and time is supreme.
That’s beautiful. Can I suggest you make a wide wave tank with multiple paddles. Then you can make curved wave fronts and freak monster waves and realistic sea states.
Depends on the environment because mangroves work best when they have the advantage of lots of shallow water. Some coastlines just don't have that option.
I have been unexpectedly educated on the science of waves and erosion... I feel more intelligent now and will find ways to work this into polite conversation. Thank you.
Best defense at all: Don't live on or near a beach. I can't say I've ever had to worry about waves where I live, because the nearest sea is the whole way across the state from me lol.
should have been better with a longer flume, higher water level and less steep beach imo but still great video and good luck to get the sand out of these bricks
Probably would've been better to limit the interaction between the wavemaker and protector by placing them further apart (much greater than the wavelength)
I would love to see if at the end of the video you just end ot with oysters or coral...comparing manmade structures to natural ones bc that's the whole point. The ecosystem is much better
What you displayed with each INDIVIDUAL SYSTEM is the reason why these Systems are usually used in conjunction with one another.
Not all of them. Some do more damage than harm when you consider the whole coastline. Some just shunt the erosion down the coast while others make the erosion worse where they are.

Bro there is a Batman Figure at the Beach maybe y take a bit To serious
Solution: mangroves will act as a buffer for tsunamis and large waves but does not completely stop them the off shore breaker is one manmade example

Build a wall, but for waves, not Mexicans

Stops erosion, but Batmans leisurely day at the beach is now ruined by a massive wall. Holy crap view, Batman!
Batman is a man who appreciates the view of a great work of engineering, his hideout is inside of a cave that was painstakingly over-engineered
Can you imagine that a thief breaks into your house and finds that it is full of comically complex traps made with Lego?

I got work tomorrow and I am watching this at 2 am
Or consider the Dutch solution: simply get rid of the water and turn everything into more land.

It’ll still erode tho, you should probably put something to defend those lands; litteraly from the water

Not if you turn the water into land, duh… you don’t need to protect something from something that doesn’t exist anymore
Would love to see these "gray infrastructure" solutions compared with green infrastructure - salt marshes, mangroves, oyster reefs - the natural systems that are actually cost-effective for long-term coastal resilience, especially facing sea-level rise.
The main difference is that green solutions regens, while gray solutions does not
Thats what make them ultimately cost efficient
the problem is that green infrastructure doesn’t always go where we want, after all we are in a randomly generated world

I've never seen Batman so relaxed at the beach...

i walked in on my dad watching this and thought it was weird but i get it now

The beach when the erosion wins: BUT IN THE END, IT DOESN’T EVEN MATTER
Every other design is elaborate, then the most effective ones were walls.

How to turn a nice beach into a lifeless fortress)) Cool
2:41 breakers are solid with none of those big gaps
Thank you for using real LEGO bricks!
You're welcome!
Who would've thought the one without holes to let the force of the waves through would be the best
Excellent engineering being demonstrated, simple and fun with lego❤
That baffle dissipator was awesome to watch. Awesome video!
Me thinking I’m smart this guy pulls up.
Really have to appreciate what coral reefs did for islands.
no idea how i ended up here but i was watching lego for 8 mins
I think the Dark Lord would be really pleased with all of these technical solutions. Well done sir.
This is the perfect lego channel
Thanks! I appreciate it!
Wish you had made a riprap with some wave dissipating blocks, like tetrapods
4:58 the waves getting baffled with this one
Mangroves are the best protectors
Depends on the environment because mangroves work best when they have the advantage of lots of shallow water. Some coastlines just don't have that option.
Thank you! And salt marshes! Need more green infrastructure, less gray infrastructure for long-term coastal resilience!
Funfact: this is how we dutch actually make waterdefences (not lego but the idea is the same)
All on scale

omg! the waves looks so realistic! and how it make the beach! very cool
Bro is underrated

Imagine going to the beach and seeing a “wave return wall” on the shore.
Who'd have thought that a solid wall that was built taller would protect the beach from erosion 🤯
best idea
As a Dutch person I can kind of approve of this video
should have been better with a longer flume, higher water level and less steep beach imo
but still great video and good luck to get the sand out of these bricks
"That wall just got 10 feet higher"
This really is an amazing video, bravo.
Thanks for the comment! I appreciate it!
The seawall is pretty cool defense. I just hope Batman is vigilant for peculiar vehicles.
Better teacher than my science class lol
Glad you enjoyed the video!
Achievement made: "return to sender"
Probably would've been better to limit the interaction between the wavemaker and protector by placing them further apart (much greater than the wavelength)
Bigger tank needed
Wow, who would have thought that the thing without holes in it would let the least amount of water through.
Yeahhh!!!! Recurved seawall
Wave return wall be like an uno reverse card
Hilarious just a straight up wall is the best solution
I would love to see if at the end of the video you just end ot with oysters or coral...comparing manmade structures to natural ones bc that's the whole point. The ecosystem is much better
This is very cool 🎉
You should try building the beach outside of the tank.
