Tokyo flood tunnels

Tokyo Flood Tunnels, an underground engineering marvel that protects the city from flash floods.

These tunnels, located beneath Tokyo’s bustling streets, are a stunning example of modern Japanese engineering.

They not only channel rainwater away from urban areas, but also provide escape routes in the event of an emergency.

They are a vital part of the city’s infrastructure, combining functionality with impressive design.

The Tokyo Flood Tunnels are a marvel of hydraulic engineering. The system, known as the G-Cans Project, is a series of underground tunnels and huge underground chambers built to prevent flooding in the city of Tokyo, which has historically been vulnerable to river overflows during heavy rain and typhoon seasons.

The project is incredible in its scale and complexity, with tunnels up to 6.3km long and gigantic underground chambers capable of containing excess rainwater. These chambers are so large that they can hold up to 200,000 cubic meters of water.

When flooding is expected, these chambers can pump the water away from the city and into the nearby river, thereby reducing the risk of catastrophic flooding in Tokyo.

The G-Cans Project is a stunning example of humanity’s ability to cope with and control the vagaries of nature through engineering and innovation.

It is undoubtedly a monumental achievement that demonstrates humanity’s intelligence and determination to protect itself from natural disasters.

if your calculations were correct you’d realize Japan’s elevation is 435 meters Asl compared to Netherlands at 30meters Asl or the soon to be fucked, Maldives at a measly 1.5 meters Asl, so,no,japan aint going swiming anytime soon Also,Nepal is 3265 meters high above ,thats 2176 maldives piled on top of each other for comparison

We live at the mercy of ocean water. Generally at the mercy of nature. If a huge asteroid falls into the ocean, it will make the waters to rise terribly and cover the whole land. The peaks of the highest mountains would be a few kilometers under water

Where will all that water come from ?

Happen s when you don’t have to invest resources in wars.
