AIRPORTS ON WATER
　　River deltas are difficult places for map makers.The river builds them up,
the sea wears them down ； their outline s are always changing.The changes in
China‘s Pearl River delta,however,are more dramatic than these natural
fluctuations.An island six kilometers long and with a total area of 1248
hectares is being created there.And the civil engineers are as interested in
performance as in speed and size.This is a bit of the delta that they want to
endure.
　　The new island of Chek Lap Kok（赤腊角）,the site of Hong Kong‘s new airport,
is 83% complete.The giant dumper trucks rumbling across it will have finished
their job by the middle of this year and the airport itself will be built at a
similarly breakneck pace.
　　As Chek Lap Kok rises,however,another new Asian island is sinking back
into the sea.This is a 520-hecrare island built in Osaka Bay,Japan,that
serves as the platform.for the new Kansai airport.Chek Lap Kok was built in
different way,and thus hopes to avoid the same sinking fate.
　　The usual way to reclaim land is to pile sand rock on to the seabed.When
the sealed oozes with mud,this is rather like placing a textbook on a wet
sponge：the weight squeezes the water out,causing both water and sponge to
settle lower.The settlement is rarely even：different parts sink at different
rates.So buildings,pipes,roads and so on tend to buckle and crack.You can
engineer around these problems,or you can engineer them out.Kansai took the
first approach； Chek Lap Kok is taking the second.
　　The differences are both political and geological.Kansai was supposed to
be built just one kilometer offshore,where the seabed is quite solid.Fishermen
protested,and the site was shifted a further five kilometers.That put it in
deeper water （around 20 metres） and above a seabed that consisted of 20 metres
of soft alluvial silt and mud deposits.Worse,below it was a not-very-firm
glacial deposit hundreds of metres thick.
　　The Kansai builders recognized that settlement was inevitable.Sand was
driven into the seabed to strengthen it before the landfill was piled on top,in
an attempt to slow the process； but this has not been as effective as had been
hoped.To cope with settlement,Kansai‘s giant terminal is supported on 900
pillars.Each of them can be individually jacked up,allowing wedges to be added
underneath.That is meant to keep the building level.But it could be a tricky task
