Indonesia Is Building A Giant Sea Wall To Save Jakarta

Jakarta, Indonesia's capital, is sinking fast. To save it, the Indonesian government has launched the Garuda Sea Wall project, a groundbreaking engineering marvel. Spanning 40 kilometers and standing 24 meters tall, this $10.5 billion sea wall aims to protect Jakarta from relentless flooding and transform the city's landscape. Discover how this colossal project, featuring 17 artificial islands and advanced floodgate systems, could secure Jakarta's future. Join us as we explore the challenges and innovations behind this ambitious endeavor. Will the Garuda Sea Wall turn the tide for Jakarta?

The goal is to prevent Jakarta, which is sinking at a rate of 5 to 10 centimeters per year, from being submerged by the sea. The project is expected to be completed by 2027. It's a massive undertaking, but if successful, it could significantly improve the city's resilience to flooding and ensure a more sustainable future.

I think indonesia should focus on saving it's existing boundaries by elevating it and not by expanding in the ocean. Look at Dubai who had build artificial islands in the ocean they are finding it difficult to maintain.

They should make the sea wall from roman concrete so the wall can use the sea water to repair itself.

No way anywhere on earth is rising by 200cm per year. Where was this GPT ripped off from?

Get some opinions from the Netherlands. They know how to keep the sea back for hundreds of years.

Instead of removing all the illegal wells, enforcement and create a proper water supply for the people, they rather build a wall they think could help them.

Do they take into account of fault line?? Earthquakes can cause more disasters. The design really looks like a Geruda, very visionary and I hope there is no disasters.

Jakarta city is the best!

The land is sinking. The sea is rising very, very slowly.

The lure of artificial islands = something governments should desist. It is quite silly and unproductive to maintain something that isn't supposed to be there naturally. I agree with developing sea-walls as business centers as it makes a lot of business sense (low investment, high returns).

Keep adding weight to the ground? Brilliant idea. You can build all you want, but your not going to stop sea levels from rising.

Actually, it's not only the Jakarta area that will sink, but the entire northern coastal area of ​​Java Island... but because Jakarta is an important city, only that area will be saved, the rest will be left as is.

While it's technically possible to fill empty underground spaces with concrete, it's not a practical solution to Jakarta's groundwater problem. Here's why:

1. **Scale of the Problem**: Jakarta's groundwater depletion affects massive areas due to excessive water extraction, mostly through illegal wells. Filling these spaces with concrete would require an enormous amount of material, time, and resources.

2. **Impact on the Ground**: Filling underground voids with concrete would change the soil's natural structure, leading to further complications. This could alter water flow, damage ecosystems, and potentially worsen subsidence if not carefully engineered.

3. **Subsidence Management**: The primary issue isn't just the voids left by groundwater extraction but the fact that the ground is compacting as the water is drawn out. Concrete wouldn't stop this. What Jakarta needs is groundwater replenishment and better regulation of water extraction to slow subsidence.

4. **Environmental Concerns**: Pouring vast amounts of concrete would have a significant environmental impact, including carbon emissions from concrete production and potential disruption to the natural groundwater system.

A more sustainable approach involves reducing groundwater extraction, implementing water management strategies, and using alternatives like desalination or surface water sources.

I'm sure they already thought of it, but they would benefit from having the Dutch Engineers who developed the Netherlands seawall oversee this project. Why reinvent the wheel when there is a perfectly good model already drawn up? It might potentially save lives.

1. Its not 200cm rising. But there is land subsidence in addition to sea level rise, making the difference in sea level and land height increase by 12cm every year. In 2014, the sea level from land could reach 2 meters. Sea water level is on 2nd floor of the house

2. Jakarta soil is sinking the main problem is the over usage of underground water that made hole under the ground, and make the soil top of that hole sinking.

java sea is not rising by as much as 2m per year, if that was the case we would all be underwater pretty soon.

[sokapokvic]

The problem is the land is sinking and the wall is sinking as well. Whatever you built on the same soil all will sinking.
