Osaka Kansai flooded and now closedBack to Forum
Osaka’s main Kansai international airport has been closed.
The airport is flooded and the situation has worsened owing to a ship colliding with the bridge linking the airport with the mainland.4 Sep 2018
Stranded passengers had to be evacuated by boat.
It is reported that Osaka Kansai may remain closed for a week.5 Sep 2018
Well, it is built on landfill, it is sinking thanks to the pounding by thousand ton aircraft and waters are rising thanks to global warming. Henceforth, that very expensive airport should not be around very long unless they replace the aircraft with seaplanes…6 Sep 2018
All true, but many other airports are built on landfill as well
What Kansai airport flooding can teach Hong Kong about the perils of reclamation amid climate change
Martin Williams says the disaster wrought by Typhoon Jebi in Japan should sound a warning to those planning reclamation in East Lantau, who do not account for the rise in sea levels or the increased intensity of typhoons that climate change could bring.

Tom, it’s been well reported but when Osaka Kansai was built, they built it directly on top of the existing sea bed. That was mud, which compresses and as soon as it was built on, it started to compress and thus sink.
When HKG was built, the mud was literally scraped off the sea bed until the constructors reached hard rock. I remember, when working for the HK Government in 1994 walking around the scraped sea bed prior to infilling with the rock blasted from the adjoining mountain that was then flattened. I also recall the ridiculous racket from the Beijing government that the colonial administration was “attempting to empty the coffers in advance of the handover…”
Interestingly, the last time I was passing through HKIA, the exhibition about the planned third runway did not require a repeat sea bed scraping but the installation of piers into the sea bed and building atop of these.11 Sep 2018
Thank you, that’s very interesting.
I suppose the larger point is that so many of these airports are vulnerable to storm surges or rising sea levels. I remember that map of Manhattan before land reclamation, and then what happened in the floods…
