Testing LEGO Sea Defences!

Using LEGO and LEGO Technic I test various types of coastal sea defences to see how well they resist erosion!
I designed and built a LEGO wave pool generator to simulate the wave action hitting the shoreline where LEGO Batman is having a break on the beach!

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.

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

[@andrewjohnson5161]

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

[@jonathanwezgray1756]

the problem is that green infrastructure doesn’t always go where we want, after all we are in a randomly generated world

[@NotBadJefferBoat]

I imagine this is how coastal engineers test their ideas

[@_D.I.G_]

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.

[@_D.I.G_]

thank you

[@user-zz1vc6us3s]

It is a pleasure to observe the course of research thought! Try to develop the idea even more with the return of the wave.

[@PastraniO1ER]

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.

[@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.

[@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.

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

[@jacklav1]

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...

[@jpmartinez9165]

Hell yeah

[@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!"

[@Jay-ci7pt]

Mangroves are the best protectors

[@scootergrant8683]

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.

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.
