Not many people will find the beauty in how the different ways a bridge is constructed, or a breakwall is designed and placed, or how air is able to be conditioned and pushed through your vents at home to keep you comfortable. The level of detail and effort we put into constructing the things we see and use everyday is quite staggering.

The part of Japan I lived in must have been a test bed for wave suppression, because you could see examples of each one of these defenses. Every few km was a different strategy. My home was about 200 meters from the "beach." As you came to it there was a ~3 meter tall wall that has a cool mural of the town's local legends. Beyond it was a wide trench, followed by another wall, beyond which were hundreds of these gigantic concrete "jacks" which acted as a rock armor. They moved a lot more though. It really felt like we were at war with the Pacific.

You seem to have missed the point of the video entirely. The best option is never to build the most overbuilt possible waste of taxpayer dollars, it's to build the solution that's _good enough_ to offer the needed level of protection while costing as little as possible. Some coasts, for instance parts that are already partially protected by coastal geometry, won't need anything more than a 2-foot high straight concrete wall. At another coast, the buildings might be far enough back from the water that minimal over-topping _might be acceptable,_ making a cheaper option viable. Civil engineering problems like almost never have a single best one-size-fits-all answer, every single option shown here _is_ the best option for certain situations.

That actually explains a lot! My grandparents used to have a house in a really nice neighborhood right on the ocean, but instead of having a sandy beach, there were a bunch of rocks and a concrete wall. I always wondered why, but now I know! It probably protected the houses in that neighborhood!

I would still pick the recurve wall because it preforms well, the rock armour as u said completely decimates the practicality of the beach as they had done at my beach ( hawker beach in Mt Martha ), also if u did the under water arc it would stop surf at certain beaches. Just my thought

I think that's the point, and the point of the video. Every situation is different, so the goals are different. Some beaches are nowhere near homes so there's zero chance of flooding. Some are great for surfing so you wouldn't want to obstruct the waves coming in. Some are more popular for swimming, so breaking up the waves further out is ideal. Some are popular for the beach, so you don't want to cover it up or make it inaccessible. Some are not popular at all, and so putting up a rocky barrier to protect a local community wouldn't be a problem. Watching this I was thinking a lot about California where I live. Because California has a subduction zone along the beach between the Pacific continental plate and the North American plate, most of California's coastline is cliffs and rocky. Many of the places with sandy beaches already have natural protection like cliffs, or huge beaches that extend inland. Also because California is stupid and they hate happiness they don't allow any private property on beaches, and they stuck a highway along the entire coast so there's usually like a quarter to half mile of undeveloped land across the entire coastline, making flooding virtually never occur. That's one alternative, don't let anyone live near the beach, no homes will be threatened.

Great video with best analysis

As 17yr geology student 20+ yrs ago, I designed and ran this very experiment but with the aim of designing coastal protection in tsunami prone areas. Using a tank does help illustrate the impacts but reflected energy has to go somewhere. On the NE coast of the UK, most types of sea defence have been used and what has happened is that the reflected energy has simply made erosion worse elsewhere. From a tsunami perspective, disturbing the amplitude is the most effective method of dissipation. But the energy has to go somewhere. And it has to be far enough out to sea to avoid the wave rebuilding. I filmed at right angles, with a grid behind the tank. This allowed me to assess wave energy under the different scenarios.

Don't mind me just ruining my sleep squedule watching waves at 4 am

This is so fascinating.

Thank you. It was very interesting!
