Architecture for Sea Level Rise on Earth

There is a high probability that all ice on Earth will melt due to a combination of factors.

If all ice on Earth melts, humans who live on land that is currently above sea level can adapt by raising structures above rising water.

I decided to ask Google what architects are thinking about this possible future, and learned that quite a bit seems to be going on.

In another topic, Calliban recently suggested building on pylons.   If this is done before water arrives, then the buildings can be cranked up the pylons as the water levels rise.  The pylons themselves would be set in bedrock or the concrete equivalent well ahead of the incoming oceans.

Re: Architecture for Sea Level Rise on Earth

This post is about evacuation of a small island off the coast of Panama.

While the bulk of the population will move to a new accommodation in the forest, a few will remain on the island as long as they can.

With the title of this topic in mind,it seems to me this is an opportunity for adventurous architects to work with an actual site to try out raised structures and other adaptations to rising sea levels.

An option that might appeal to some is an elevator platform that would rest at sea level when conditions permit, but which would lift above the waves when necessary.

Panama prepares to evacuate first island in face of rising sea levels
MATÍAS DELACROIX and JUAN ZAMORANO
Updated Sat, June 1, 2024 at 12:18 PM EDT·5 min read

and ...

GARDI SUGDUB, Panama (AP) — On a tiny island off Panama’s Caribbean coast, about 300 families are packing their belongings in preparation for a dramatic change. Generations of Gunas who have grown up on Gardi Sugdub in a life dedicated to the sea and tourism will trade that next week for the mainland’s solid ground.

They go voluntarily — sort of.

The Gunas of Gardi Sugdub are the first of 63 communities along Panama’s Caribbean and Pacific coasts that government officials and scientists expect to be forced to relocate by rising sea levels in the coming decades.

The first response of the government of Panama seems to have been to move the population inland. That is probably less expensive than trying to find a solution that would allow continued living on the island.

Every year, especially when the strong winds whip up the sea in November and December, water fills the streets and enters the homes. Climate change isn't only leading to a rise in sea levels, but it's also warming oceans and thereby powering stronger storms.

The Gunas have tried to reinforce the island’s edge with rocks, pilings and coral, but seawater keeps coming.

Re: Architecture for Sea Level Rise on Earth

For SpaceNut re contributinns showing where flooding is likely!

Thanks for these maps. They show where capitalists can allocate funds to provide a useful service in return for fair compensation.

This topic is set up to provide (or at least point to) solutions.  This topic is NOT about whether climate change will occur or how soon. This topic is about how astute business people can identify opportunity and prepare to take advantage.

I understand that not everyone has the background or even an interest in entrepreneurship.  This topic may be of interest to readers in general, but I am hoping we attract the young people who are going to be leading the project teams to create safe and comfortable living accommodations for folks who want to live in the new coastal areas that appear likely to become available.

The regions of interest will not be far under the surface unless all the glaciers melt. Instead, they will be similar to existing coastal regions, where tides occasionally cover everything briefly, or hurricanes sweep onshore and cause damage.

The housing architecture that is needed is already showing up here and there.  There are two basic strategies that seem likely (to me at least) ... One is the pillar concept that Calliban suggested.  The other is the submarine method, which is perfectly feasible, since submarines have shown how to tuck under the waves to stay out of the turbulence.   All solutions will require investment of time, energy and money, but the opportunity to live in the soon-to-become-available coastal regions will justify the investment.

Re: Architecture for Sea Level Rise on Earth

We hear politicians say talk about "fighting sea level rise", so I want to post some facts.

Post glacial sea level rise. This shows sea.level has risen continuously for the last 20,000 years. Most people have heard that ancestors of aboriginal people in the Americas walked across the Bering sea land bridge. The land has been called Beringia. It flooded due to sea level rise as ice from the ice age melted. What most people don't realize is that sea level rise never stopped. Glaciers are left-overs from the ice age and are still melting.
Post-Glacial_Sea_Level.png

Several Roman ports and coastal cities are under water. This is due to sea level rise. Olbia off the Mediterranean coast of France, Baiae on the northwest short of the Gulf of Naples, a Roman port off the coast of Portorož Slovenia.

Today sea level rise has been measured by a US federal agency called National Oceanographic and Atmospheric Agency (NOAA). It's been measured since 1993, and is very steady. It isn't increasing nor decreasing. It's 3.2 millimetres per year. It varies from 3.1 to 3.3, but averages to 3.2 with no change in trend. That's 3.2 cm per decade or 9.6 cm (3 3/4 inches) over the next 3 decades. Between 2024 and 2101 (the start of the next century) sea level will rise by 3.2 x 246.4 mm. Rounding off to 2 significant figures that's 1/4 metre or 9.7 inches. We can adjust ports.
slr_sla_gbl_free_ref_90_500.png

The coast of Nova Scotia in Canada has another problem: ground subsidence. The tecktonic plate is subsiding. During the last ice age, Canada was covered by ice kilometres deep. Over southern Manitoba where I live it was 10 km deep. That weight pressed the tecktonic plate down into the mantle. But as a person lying on a foam pad floating in a swimming pool, the weight caused the centre to subside but the edges to flip up. Now that the ice is gone, the tecktonic plate is rebounding. In southern Manitoba it has finished but northern Manitoba is still rebounding. Thousands of years from now, the Red River will reverse water flow. But the edge of the continental plate flipped up. Today the edges are subsiding down. The west coast is anchored by the Rocky Mountains, but the coast of Nova Scotia is subsiding. It's sinking at 10 to 15 cm per century. If we use the higher figure, over the next 77 years that's 11.55 cm.  Add to sea level rise and coastal waters will rise by 36 cm (0.36 metres). One individual is going to town councils show what would happen with sea level rise by 3 metres. That's exaggeration by roughly 10 times.

Re: Architecture for Sea Level Rise on Earth

For a business one must have a state, town or city and last but least the landowner willing to pay the price to keep what they own from vanishing.

Building a seawall costs $25,000 on average, with a wide range between $10,000 and $100,000, depending on the size and type of seawall.

https://www.angi.com/articles/how-much- … eawall.htm

How much does a seawall cost?

$150 – $600 seawall cost per linear foot
$15,000 – $60,000 Average cost to build 100’ seawall

Materials wood, steel, concrete and even others...

Re: Architecture for Sea Level Rise on Earth

For RobertDyck re Post #11

Thank you for this interesting and timely addition to the collection.

This topic is intended to hold posts about how to prepare buildings for sea level rise.

Your post reminds us that there will be subsidence in some areas, which implies to me that if the regions of concern are near sea level today, they will be below sea level tomorrow, even if the sea were not rising.

The figures you cited that came from NOAA are highly likely to be correct.  The historical record certainly needs to be taken into account. The issue at hand is that glaciers are (apparently/reportedly) melting faster than had been expected.

Please continue adding helpful data to this topic as it comes to your attention.  I doubt you're going to find much good news based upon current observations, but you might, and if you do it would be welcome.

Re: Architecture for Sea Level Rise on Earth

Yes, low lying areas have to deal with sea level rise somehow. Holland has used dykes to hold back the ocean, reclaim some of the land lost to sea level rise. Whether it is reclaimed or gained depends on how long you look at history. Doggerland submerged about 6,500 BC. That's 8,500 years ago, plus or minus a century. You could use dykes, or relocate people inland, or some other strategy.
1920px-Doggerland3er_en.png

Canada is dealing with a federal government obsessed about carbon emissions. As if reducing carbon emissions in Canada alone will somehow stop global climate change. Our economy is destroyed. I'm not arguing for doing nothing, but am arguing for learning the actual science before creating government policy, and NOT listening to political activists. At this point I could spout a long stream of expletives for political activists.

Re: Architecture for Sea Level Rise on Earth

Note: according to ancient Egyptian documents, their ancestors lived on an island in the Mediterranean. That island sunk. They moved to the mainland. The island was not Atlantis, it was a different island. Some people pointed out the oldest stone buildings and monuments seem to be built using very advanced stone working techniques, and those techniques gradually got more primitive over time. That's backwards to what you would think. So people must have developed stone working technology very long ago, longer than traditional history records. Oldest records do support that conclusion; that history is far older than most people believe. But this discussion is about sea level rise. My point is ancient Egyptians dealt with flooding of their island, their world, by moving to a completely different location. Today we think of Egyptians as living and belonging to the Nile river. But they didn't originate there, they moved there after their island was flooded. They brought advanced stone working technology, and we don't know how many other technologies with them. Agriculture? Göbekli Tepe in what is now Turkey was occupied between 9,500 BC and 8,000 BC. That's what we know. It was buried, and we can carbon date the soil with which it was buried. We don't actually know when it was built. There is a field within walking distance of Göbekli Tepe that has evidence of wheat carbon dated to 22,000 years ago. And that isn't the oldest wheat. There is evidence of wheat in the Levant carbon dated to 26,000 years ago. So history is a lot older than most people think. But back to sea level rise. Ancient Egyptians moved from an island to the mainland, are now associated with the Nile river. Others may have to permanently move as well.

Re: Architecture for Sea Level Rise on Earth

This is a follow up to RobertDyck's interesting and timely report on sea level rise since the last ice age ...

https://coast.noaa.gov/slr/

This site features a map that shows flooding that can be expected for various levels of sea level rise.

The map shows Canada and nations South of the US, but the animation does not appear to include them.

The map does include focus on selected islands;

This next quote from NOAA may be more useful:

People also ask
What is the projected sea level rise for NOAA?
2022 Sea Level Rise Technical Report
Sea level along the U.S. coastline is projected to rise, on average, 10 - 12 inches (0.25 - 0.30 meters) in the next 30 years (2020 - 2050), which will be as much as the rise measured over the last 100 years (1920 - 2020).

The predictions of any government agency, or private one for that matter, are open to amendment if inputs change.

The rate of melting of glaciers would (presumably) show up as changes of projections of sea level rise.

Most predictions that I found in scanning Google's collection seem to show about a foot of sea level rise along the East coast of the US in the next 30 years.  However, that's the average.

Hurricanes and high tides will raise water levels temporarily.

It seems to me a prudent property owner in areas subject to flooding would take precautions.

It appears that many folks ** are ** planning ahead.

A recent report highlights that since 2010, the Gulf of Mexico has seen sea levels rise at twice the global average rate. Tide gauges from Texas to North Carolina show sea levels at least six inches higher than 14 years ago.
