Testing LEGO Sea Defences!

[@OleDirtyMacSanchez]

What you displayed with each INDIVIDUAL SYSTEM is the reason why these Systems are usually used in conjunction with one another.

[@scootergrant8683]

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 😭

[@Karagianis]

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!"

[@jasonalbert6251]

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.

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

[@Kai...999]

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.

[@dactarik2615]

The main difference is that green solutions regens, while gray solutions does not Thats what make them ultimately cost efficient

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.

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

[@Diggywet]

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.

[@Memer9456]

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

[@marvinschiller7909]

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...
