- Coastal cities around the world are grappling with sea level rise. And building a seawall? Not so fast. While a sea wall can be effective in certain scenarios, it can make the effects of sea level rise worse. That’s why municipalities are looking into creative alternatives.

As a dutch civil engineer i can say there are many other solutions to these problems look up the delta works and the afsluit dijk
Unfortunately, the underlying Miami rock is pretty porous (as mentioned in the video). So there's limits to how much that will work.
How about with mangrove?
@@joshuazelinsky5213 As a dutchie, we are pretty lucky that early on it was understood that we CANNOT build on thee beaches and dunes. This has saved us so much money and lives. If we had built on that sandy ground, we would be in the same situation (we actually did in some places and it is a pain in the butt to deal with now.)
@@Azivegu Yeah, no question that a lot of the issues for Miami are very much self-inflicted.
Civil engineers from Dutchland? What kinda s-hole country is that? Dude real engineers use capital letters and know how to end sentences.
Restoring barrier islands (no living on those!) and salt marshes is better than “hard” flood controls.
they should just make the ground deeper so the water goes down duh 🙄
@@lostpockets2227 no...that's not how it works bud, there are such things named continental shelves, which is just a rapid cliff that goes down deep and is almost leads to a trench, and if they made it deeper, the sand would eventually fill it back up...
@Viracocha the entire state of Florida needs a great sea wall
yes and no --- the way (and speed) the climate is changing/has changed means traditional environmental means won't really be sufficient. The best option is to relocate people and give the land back to nature and convert quickly quickly quickly to clean energy on all levels from the car you drive to the food you eat.
"We're a coastal barrier island"
Me: ...that cut down all the trees, ripped up and paved over all the marsh grass, dredged swampland, and dug holes in the ground for plumbing, and built tall heavy buildings on top of it all...
My family is from MD and coastal NC. We're all trying to rebuild oyster beds, re-establish marshland, and build up new sand bars.
Result: Kaboomsh! People should talk about relocating cities along with changing to EVs
@@teemum.9023 as a mechanic EVs are the biggest pieces of shit in the world. just pray that you never get into anything more than a fenderbender, because if a battery cell is damaged, theres no way to fix it as they are chassis mounted. youre just gonna have to buy a new car
@@monkey.moments8272 if a battery inside the cell is damaged… let’s just say lithium-ion isn’t the best choice for your car not catching fire, repeatedly as thermal runaway cascades from section to sections of the battery. (Lithium-polymer is better, but it’s not being used in cars yet. There’s new work on algae based batteries that are much safer, and charge time to 100% is much faster.)
@@joermnyc i honestly think a carbon neutral synthetic gasoline is probably the best solution in our current environment. the infrastructure just isn't there for ev's yet (at least in the us anyways with our third world infrastructure ratings)
It's hard to understand why anyone would move to a flat coastal area if they're under the age of 70 or so given the escalating nature of climate change causing worse hurricanes and rising sea levels. Seems unlikely that Florida will go full Netherlands and anything short of that will likely be insufficient.
Makes people like you hard to understand because in the Netherlands way older people all live in flat coastal areas below sea level even. Just like video about toddlers pretending to be 'engineers' in adult bodies I guess? Oh no these walls will block marine life and topple over! Netherlands ... raises entire sea barrier up for marine life. Then lowers miles of sea wall when the sea goes hurricane. Nooo how do we break water??? Ehmm maybe use wooden poles extending into the sea every 100 meters? Done since the 16th century?? Then again if you close a levy door on one side the size of the Eiffel tower and the one on the other size? People will just go into denial and refuse to believe what they see with their own eyes.
Yeah it's unfortunate that people continue to move to these areas that will be under water in 20 yesrs.
Two of the world's leading climate hoaxers,Barack Obama and Nancy Pelosi actually invested millions in seafront properties recently so it's not like they believe their own BS.
@@tellyboy17 That's an insane conspiracy theory. Every rational individual would jump at the chance to throw millions of dollars away by buying a home that will be destroyed within a few years.
@@dl2839 People's willingness to accept and live by lies propagated by an elite that demonstrates through its own behavior that these are in fact lies that they don't buy into themselves is mindblowing and the stuff totalitarianism is based on. Academy of Ideas has a great video on this:
th-cam.com/video/6VfJ0BJvt7Y/w-d-xo.html
Since I live in Indonesia, we have 17,000+ islands. The natural solution such as coral reefs have been quite helpful in the islands I've visited
Houses below seawater level are now partly underwater and the people dwelling in them suffer greatly. The only help the government can offer is to relocate all these people to higher dry lands.
@@solapowsj25 i see your pov 😉
Bad idea to watch this before I go to bed living on a tiny island between Miami Beach and the mainland.
Star Island?
Some might say it's a bad idea to live there in the first place :)
Can I come over? 😅
Me invitas? 🥺🥺🥺
The trick is to realize that almost all of the scare stories people tell you are just that: stories, usually devised to scare you in accepting agenda's that involve separating you from your money and you freedom. Good night!
Cheddar: sea walls alone won't stop the rising seas.
The Dutch: lalalalalalalala, I cant hear you lalalalala
Also the Dutch /used all methods
Thats why we Dutch people arent only using sea walls to protect us from rising sea levels :P
Take a look at the deltawerken in the Netherlands, we've had our challenges and did our research. Our dijks can withstand the sea for at least another 100 years.
Flooding from rivers is the mayor issue these days, not the sea.
The problem is the limestone the hostess referred to at the beginning of the video. Seawater penetrates into the porous bedrock of SE Florida so there’s just no way to stop it over the long term except reversing climate change…which will likely take a few centuries’ worth of technology and willpower.
Miami is already losing drinking wells to this process as they become salinated.
this is true for the Dutch as well, they just liv in denial
My family member had a pier on their property by the intercoastal waterway in NC. A hurricane came by and destroyed the pier. The pylons were left standing. My relative decided not to rebuild the pier the same way. Previously it was all nailed together to form one piece. This time he put floaters underneath the pier top and made it free to rise and fall on the pylons. The next storm caused the pier top to rise but it returned to water level after the water receded. Success!
This documentary has made a large mistake by not looking at the Dutch situation. The Dutch have been making modern seawalls since the 1950's successfully. This knowledge has been exported to a lot of countries, like Indonesia and the US (New Orleans).
Better than trying to keep the inevitable water out, is to plan for when the water gets in.
In many beach communities all houses must be built on stilts. Assume your first and second level walls will be lost in a storm and the upper floor framing is reinforced to stay intact.
Stilts ... lmao! Just being a clown or are you an actual clown on stilts?
Build canals from the Mediterranean Sea to the basins in the Sahara desert, as sea levels rise they fill the basins to become inner seas, AtlasPro channel shows the basins nicely
And might turn the region into another vacation destination
erm i doubt this would have any appreciable effect , if you say had a 1Metre Sea level Rise, then to mitigate that with Basin's, you would need to create a Basin 360 Million Sq. KM (i.e. the surface area of all Earth Seas and Oceans) 1 M Deep, so make it 2M deep it's still 160 million Sq. KM, i.e. the Size of earths Land Mass.
Sure it would scale but you would need to make it very deep . As ocean are contiguous any basin would effectively drain from the World's entire Oceans.
Back of the envelope , the Sahara is 9 Million square Km, Earths entire Land mass 150 million , Oceans and Sea 360 million. So if you filled the Entire Sahara as a Basin it would need to be , 36 Metres deep for every 1 Metre drainage. So you want to drain the Ocean by 2M it would need to 70 metres deep.
That's using the entire Sahara which is the size of the USA. Obviously you couldn't , because just submerging the Sahara would have untold unforeseen consequences and it would cost trillions and be undoable.
in Short there is a lot of Ocean , to create a Drainage basin that would have any effect beyond negligible would be prohibitively expensive , create untold consequences and just not be viable.
Realtor: No to walls and other measures! It will lower property values!!!
That chunk of future seabed they purchased will be so worth the money though 😏
@@suzannax wave crashes into the backyard: “,,, comes with a salt water swimming pool!”
"Be proactive"
If only the people in charge would start...
How's those natural reef gonna work when they are getting bleached by ocean acidification? I'm pretty skeptical about how we gonna hold back the ocean when it's basically inevitable that we will have at least a 3 foot rise if not 6
At some stage in the future coastal communities will have to think about relocating to higher ground. If so then start planning for it now and do it little be little over the next 100 years or so. Tony Burch - retired coastal engineer
Two meters (6'-8") of sea level rise by 2100 will settle this for good. Even the Nederlands will face reality. Miami underwater will be a pretty great scuba destination.
The problem is that the sea level wont rise that much
Also the Netherlands doesn’t have sea walls in the American definition.
@@Matt11Cav true,... it will be way worse (whether or not before or after 2100)
Dutch sea walls are prepared for 1,5 meter rise, and we have no hurricanes. However, the river dikes are more of a problem: when your whole country is about zero meter above sea-level now, than all rivers will have a level higher than the surrounding land in 2100. Already working on that.
The title is very despetive, rising sea levels and tides are one of the only example where soft systems have no effect, since it refers to the increase in water level not in climate changes causing violent waves
Increase in water level IS CAUSED BY CLIMATE CHANGE!!
@@jayjohnson8403 yes, that wasn't my point
@@caijones156 Each sentences makes no point. Cos you do not end sentences? How old are you?
@@MrFlatage honestly if you couldnt understand that comment because i omitted 2 full stops then id question your age
@@caijones156 Haha pointing the finger? That is very childish of you. As expected from someone uneducted. No wonder everyone here posting mentions not getting your point and corrects you. See it like a 1st grade written exam? When your old enough.
There are lots of solutions that aren't seawalls. Glad that you mentioned living shorelines. Also the areas that are next to the seawalls erode due to along shore transport of wave energy.
I live near ECU and you always see the students at the beach, it's kinda cool.
Its like learning secondary school geography all over again!
How about cutting CO2 and methane emissions that is causing heat to be trapped in the air and making the polar ice caps melt, thus causing the sea levels to rise. But that would require major changes in behavior which sadly people don't want to make. 😞
Basically!
Technically the arctic doesn't contribute, floating ice displaces a volume of water equal to its melted volume. However, all the glaciers on land like Greenland, Antartica, and smaller mountain glaciers are contributers.
Melting ice isn't the only reason for local sealevel rise, for instance in NYC half of it is from the ground sinking as part of the glacial rebound of the Canadian Shield. (All the iceage glaciers were really heavy and pushed the shield down which caused the edges to bubble up and now that the ice is gone the land is returning to its original shape)
Also sealevel rise is far from the only reason to address the problem of anthropogenic climate change.
This is an interesting problem for coastal cities like Miami and New Orleans. With climate change getting worse, the different solutions will be tried out varyingly and the best identified.
I have lived in FLorida and sea level has not changed in 100 years. You must be WAY smarter then the RICH and the politicians that are spouting this nonesense because they are ALL buying oceanfront and islands as well.Oceans are not going to rise at all
My thoughts that It might help to save Miami but it costs a lot, actually. Also, I'm wondering how this walls will sustain the sea power and for how long these kind of walls can last without erosion. Very Interesting video, Cheddar! Your graphics in the videos and animations are insane!
It may be better to move higher up or change the way you build things. For tall buildings modify or abandon the first floors. Short building may be lost.
We’re so incredibly fucked and for some reason this past year of endless natural disasters isn’t scaring those with the power to change things. They will only take action when it’s far, far too late.
As they said in the video: We should be proactive, but we live in a reactive society
I wouldnt be surprised if we're far too late to stop climate change when we as a society are finally to combat it.
Certain people whine about the sacrifices we have to make, but the sacrifices we will have to make if we do nothing and let climate change will do its bidding will be way larger.
We are doomed. Right up to the end we expected miracles.
All of Miami needs to watch this.
We already know that there has been Continental and landmass drift from a central point throughout millions of years. This is due partly to underwater volcanic activity on the fault lines and from coastal erosion and sediment deposit on opposing coastlines. In the West the East coasts of any landmass is subject to erosion whilst the west coast is subject to sediment deposition, and the opposite is true in the East. There are areas of the western coasts (in the West) where seasonal highs and lows of unpredictable tides have given cause for sea walls to be built to make those areas useable for Towns and Cities, but otherwise would not have been necessary. In my home town (on the west, in the west) around 60/70 years ago the tide could vary in depth throughout the year to up to around a half mile, with much of it being marshland. The estuary provided access to boats and small ships to villages now considered far in land. A sea wall was built in order to protect the marsh which was often used as farm land for grazing and prevent occasional flooding inland. In the areas outside my town this was not done and the tide has naturally subsided due to sediment deposition. This is also the case for our beach which has over the years turned in to marsh land and the sea goes further out each year. The sea wall would have little necessity anymore other than preventing our promanade from turning back to marshland, but we certainly wouldn't be flooded. I've seen no evidence of rising sea level where I live and there hasn't been any for the last 70 years I'm aware of. The estuary is no longer passable (even at high tide) for any craft and is more or less silted up acting only as a drain from waterways inland. This video is informative for the east coast areas (in the west) but I don't see how it has anything to do with rising sea levels.
Oh, 7:03 never thought I'd see Whitehaven, tiny town in the North of England on Cheddar, though I suppose you did try to invade us starting there so its fitting.
Seawalls can save, depending on how you've done it. Most walls were built vertical, so when the force of seawaves it only goes on top of it. Why not fix the design like a loop that turns back the waves. Even if it is just low the effects of seawaves are not that bad than the vertical. In Dubai, they even built the tallest hotel using only ready made cemented stones piled high around the hotel. In Netherland, they built road crossing the sea just to block atlantic seawaves. If you want a lasting seawalls, before you pile stones along the seashores, be sure to plant first mangroves that will serve as a barrier and good enough to break seawaves, seawaves will not dig deep and it grows even high planted among stones. The high intricate roots can served as sea creature's breeding area, it also catched debries brought by strong seawaves. Netherland, has best experienced countering big seawaves for almost a century, Florida needs their expertise from them, as of today, they're able to increased their lands. Countries with wide coasts and often visited by hurricanes and storms must now start fixing their seashores, letting the rain from in goes directly to the sea, will only bring eroded inland and hills soils and silts to the sea, the result is adding sea level rise.
You could also try not filling in the marshes that act as natural shock absorbers for the inflowing water...
I invested in life vests! And i left the beach and moved to suburbs of miami. If i want the beach 🏖 i take the expressway and drive 10 minutes. (Plus save money, parking problems, and being isolated on the beach. (Fyi miami beach is an island outside of city of miami.)
6:06 sea hives for wave strength dissipation.
I wanted to study this for my assigned group project in grad school, but no, my group chose Uber affecting Taxi’s in Boston bc EVERYONE uses Ubers. Not me, and I live in a coastal city so this actually effects my life.
Tell the Netherlands that sea walls don't work and create uninhabited barrier islands
The Netherlands carefully planned their sea walls to the smallest detail, they planned for everything. They didn't just build a wall, they have pumping stations that remove the water, a system of multiple doors to control the flow, sand replenishment machinery to restore beaches that get eroded, and so on. The flood control system in the Netherlands is one of the most remarkable deats of engineer ever created. Calling it "a sea wall" is a major understatement.
Those walls proposed for the US seem to be more on the lines of "Let's do this for now, we'll worry about the details later".
@@LuckyBird551 Yes, I realized that Some are still powered by Windmills. The same general idea surrounding Miami Dade would work with the proper planning
I never knew about sea hives, they look very promising
I lost my family house, it's effects are devastating.
There is also the fact continuous sea level rise could not be stopped by these projects, no matter how tall you make them. Not unless you make a shatterproof dome. There isn't any telling how high the water may rise for good.
Yes. Hopefully we can limit the affect though, by reducing emissions etc.
Even if we can't stop climate change. Every little bit we do should reduce the damage
You can tell exactly what the worst case scenario is, step 1 is take the known amount of ice on land and convert to its melted volume, then have a computer to the calculus of adding that much water to the ocean using topographic maps to know how far it will rise. Its fairly basic math in theory, just a lot of calculations which computers are perfect for doing this sort of number crunching.
That said if all the ice on earth melts we will have bigger fish to fry than the fact the entire state of florida is underwater. (As well as most flat coastal regions having the shoreline advancing many miles inland)
Sea walls are effective in appropriate environments. But erosion around a sea wall from underneath can not only remove the wall, but it can allow the water to creep into the rock the buildings are built on. Limestone is subject to creation of sinkholes, which -like at Bowling Green, KY's Corvette museum - can sink large swaths of land. Mammoth Cave nearby is connected to many caves around it like Onyx cave, and it is ALL limestone in what is called Karst topography, which is caves of limestone carved by underground rivers. The Green River there is one such river.
I'm worried that water that gets into limestone would create caves and enlargen existing ones to weaken the rock above it under the buildings.
wow, I never knew this
It’s weird how the beaches near me don’t seem to be shrinking 🤷♂️
The Will Smith song 'Miami' was stuck in my head while watching this
I love miami i hope that beautiful city is protected
no idea. can't remember all this
In the end I think Florida will be mostly flooded in the future.
Meh, I'm in the Orlando area and I'm not young. I should die before we're underwater. the coastal areas are owned by rich people who wouldn't give a crap about my welfare.
I see the Stanley Park seawall @1:42
I witnessed extensive seawalls and horrid geometric concrete structures littering the Japanese coastline in 1992. It was offensive to my surfing/beach loving nature. Not sure how successful these have been considering the more recent history of Japan and tsunamis. Just when considering the appreciation of natural coastlines versus "the next engineering hack", I reckon it was (and will be) a failure to pile [humanly] heavy chunks of stuff against the almost infinite power of the ocean.
I tried to buy a house on the ocean at a discount because of rising sea levels, but they just laughed and somebody else paid more than asking price.
Why didn't you buy a house at discount becouse its 6-8 feet higher than the coastline.
Have you shared this with these cities yet????
This video is over monetized. Preload and an ad before 2 minutes, and one at 4 1/2 minutes, for an 8 minute video.
Fun fact the seawall costs only about 10 million a mile. The extra 1.2 billion is graft, corruption, and consulting fees. I made these numbers, but is anyone surprised?
walls create a bowl. bowls fill up. ask new Orleans, 2005.
Must decide which cities to save. Ground water:cisterns contaminated by saltwater. I would not purchase in Miami as sealevel rise occurring much faster rate. Levies vs sea wall
Seawalls are absolutely 100% nessisary. It doesn't mater that they don't protect the beaches from eroding, because in ~50 years with the rising sea level, all current beaches will be under water anyways. If we want to prevent losing coastal *land*, we need walls to hold back the rising water.
Now i am in favor of using green infrastructure such as: reefs and mangrove trees to prevent erosion and break waves naturally; as well as coastal marshlands to act as sponges and soak up the excess water during high tides and slow down the flow.
But while these methods work well for slowing the tide and breaking the waves, they do nothing to stop the rising sea level from taking our low elevation coastal land. So ultimately the best solution is a combined approach using both walls and Green Infrastructure.
Tell that to the Netherlands.
Onze dijken zijn de beste!
Thats why we Dutch people arent only using sea walls to protect us from rising sea levels :P
What works in another doesn't really translate to other.
Wouldn't it just be easier to move inland?
One look at global tidal gauges shows that as CO2 rises exponentially the rate of sea level rise remains linear, so anybody who thinks the two are connected and reducing CO2 can stop sea level rise is in for a disappointment. Sea levels have risen 170 meters since the last ice age and unfortunately that process is still going on but luckily very slowly.
Historically there has never been a link between global temp and CO2 either. Sometimes the temp has gone up and CO2 has stayed the same...and sometimes the temp has gone down and CO2 has gone up. That CO2 is the environmental "boogey man " is a creation of the left for the purposes of causing enough fear that people voluntarily agree that they must adopt "socialism" as the only way to "save the planet".
@@markanthony3275 Actually there is a link historically but it's reversed: when temps go up, CO2 goes up. That's because when oceans warm up they can hold less CO2.
But yeah, the idea that we're all going to drown because we increase CO2 levels is based on junk science produced by funding chasing "scientists" and adopted by political opportunist using the age old trick of using fear to rob people of their money and freedom.
How about retreating? Your country is big enough. Don't allow new buildings. Problem solved.
Living in Blackpool on the UK we have a 55 meter high seawall 20 miles long. Mother nature has no chance
55 meter?
@@sc1338 it's got barbed wire on top, goes right round the town, with guard towers at regular intervals. It doesn't protect Blackpool from the sea, it protects the UK from Blackpool..

I feel like this video could be more informative, but the focus is on the terrible design of vertical walls only
4:32 looks like a bird-plant man reading a book lol
Do you ever heard of Netherlands . This half of country below sea level.
I’m no expert but couldn’t an artificial sand bar hundreds of feet out be affective as well, stop the wave hundreds of feet away
It would probably just get washed away, but that is also exactly what barrier islands are. Atlantic city is every bit the afront to the natural order as Phoenix and Las Vegas are, its just less obvious than wasting water in the desert on grass and fountains.
The difference between a natural and artificial barrier island is that the ocean builds and maintains the natural ones but any artificial barrier will have to be maintained at great expense by humans. The simplest solution is ban the construction of any permanent homes on these islands and let them be returned to nature or kept as little more than camps for boaters to dock at. (Placed on stilts and to a very specific building code)
It’s cause their not building a 50 foot sea wall on the ocean I mean I don’t believe Miami will be underwater in 2030 but in 2017 I saw all these streets in Miami flooded and why it will hard to build a 50 or 70 foot wall anyway
Peace and Prosperity.
Since the sea levels are rising anyway, why not just use the oil pipelines and convert to water pipelines, pumping sea water into the middle of the continent for desalination drinking and farming uses. That could lower the sea levels if enough is pumped to the centre of all continents.
You will never be able to pump enough to have a measurable result.
...Jeez she could explain grass growth to me
Nobody is actually living in the property. Miami's property is one of Blackstone's largest portfolios.
@1:15 she just bypassed on the story about vertical walls.
To cover a subject like this without mentioning and looking at the Dutch is a missed chance...
Two words, the Dutch.
Jazeker
biggest flaw in this video: not mentioning the Dutch....
we figured this stuff out since the 60s/70s....
JAPAN : LET ME INTRODUCE YOU 400KM TSUNAMI WALL
Ultimately, people should just move in the next 80 years, as nature reclaims these islands
i hit the big mighty red button, i did it.
The Dutch are on their way to Miami lmfao
Why does it feel like I watched this video before?? Just me?
I LOVE WILLIES
Note that the answer lies more in maintaining natural barriers than in designing a better seawall. Public stewardship >>> private ownership!
Blade Runner 2049 begs to differ.
Oysters. Start an oyster cluster. They build high on top of eachother
I do like this channel a lot but damn do they love clickbait like the arrow being pointed at the house saying it's the problem well no shit but I still clicked on it lol
i can think of about a hundred different reasons to not move to miami lol
Well they will if we make them tall and thick enough
Maybe they should consider building and moving the cities to more commonsensical places that are higher above the water.
The CARBON emissions from building are not factored in to the COST!
sea wall prevents wave bro not rising sea , there must be understanding here
2 yers later: house assurance companies are leaving Florida, car assurance becomes very expensive. Florida can’t be saved. People just has to leave.
We need to promote more inland migration.
MIami haven't had a major hurricane in the past 10 years. I mean Hurricane Andrew type hurricane
Just go to The Netherlands and learn how it's done.
I'm told that Dolos knucklebone sealwalls work best to break up wave energy. They just plonk them in a pile in front of existing walls and they stay there for decades laughing in the face of storms.
Or the Levvel-blocs, which are cleanly stackable.
We should move the sea to the desert🤭
You might consider moving the mountains to low lying areas. Lift all the cities up and put the mountains underneath...😉
Oyster used to be the natural sea wall until human start consuming them.
Call the Netherlands
Basically, People sold their houses at sky high prices to idiots who are moving in only to lose all future sales of their houses. Good luck on getting money back.
I don't get it why, instead of spending money on sea walls we spend that money on stoping climate change?
This is really just slapping a bandaid on the preventable result.
@@GeoCaptTerror yeah like seeing a knife flying in your direction and instead of trying to doge it you ready the first aid kit
Because its unrealistic to assume it can be stopped. Much of the world is still developing and quite poor. They cannot afford the latest technologies so they will continue functioning as best they could. They will continue pumping out CO2 for quite some time yet.
@@manickn6819 what's unrealistic is the audacity to blame developing countries... that btw are doing a better job at switching to cleaner energy than us

Simple answer- World needs the dutch

Also, in fifty years, the coastline is not going to change that much. The amount of change won't be noticeable for a significant amount of time, mainly because most of the change will come from geological and tectonic events.
The seas will keep rising, as the icecaps melt the water will rise 265 feet.
