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.
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.
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.
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 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
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.
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.
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.
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.
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.
Probably would've been better to limit the interaction between the wavemaker and protector by placing them further apart (much greater than the wavelength)
one this it doesn't cover is that the waves are typically hitting the beach at an offset angle. hence the perpendicular jetties for sand retention that are currently in use. personally I feel like either the mesh or stepped baffles should be buried a bit up the beach in order to prevent erosion after a certain point but also allow a degree of natural erosion/deposition while still retaining natural beauty
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.
you say the least erosion but most of that was caused by water getting past either side where it didn't fill the entire width without that gap there would have been no erosion. a more curved version of that last wall a bit like a snow plow should be installed along all coastlines prone to severe flooding and tsunami.
What you displayed with each INDIVIDUAL SYSTEM is the reason why these Systems are usually used in conjunction with one another.

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

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

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

The beach when the erosion wins: BUT IN THE END, IT DOESN’T EVEN MATTER
As a sea coast protection engineer, I approve so much
I never even _thought_ about undercut. This taught me a lot more than I'd thought it would!
For once GCSE geography came in clutch with the knowledge
i walked in on my dad watching this and thought it was weird but i get it now
Merci pour ton travail Seb, genre vraiment
In conclusion build big wall
That baffle dissipator was awesome to watch. Awesome video!
Wonderful! Thank you for your work!
Thanks, I appreciate the support!
This is a great lesson in shore erosion and the methods of preventing it.
Excellent engineering being demonstrated, simple and fun with lego❤
So what I've learned is to put a halfpipe inbetween a beach and ocean

Really have to appreciate what coral reefs did for islands.

All on scale
so cool! I did a test on tsunamis once where I tested different levees and the return the wave worked best for me too.

Imagine going to the beach and seeing a “wave return wall” on the shore.
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.
Who'd have thought that a solid wall that was built taller would protect the beach from erosion 🤯
As a Dutch person I can kind of approve of this video

you say the least erosion but most of that was caused by water getting past either side where it didn't fill the entire width without that gap there would have been no erosion. a more curved version of that last wall a bit like a snow plow should be installed along all coastlines prone to severe flooding and tsunami.
