![well the works began in 1882 after quite
an ordeal with
studies um financial issues how much
earth and rock
would need to be dug out to produce a
trench like this
between the peloponnese and greece
that's
more than 12 million cubic meters of
earth that has been excavated
here and we're talking more than two
thousand workers
that were involved in the project also
dynamite and nitroglycerin
was one of the first projects of uh
construction
like the canal that has been used here
but nitroglycerin is really dangerous
it is but um they've tried it so you can
see the results
the maritime canal was completed in just
10 years
the corinth canal's simple construction
is called a sea level canal
meaning that it's hewn out at the level
of the two seas it connects
which feed it constantly with saltwater
[Music]
the technical challenge becomes much
greater when fluvial channels have to be
bored over long distances
rivers and watercourses must be diverted
to supply these artificial channels with
fresh water
and force them through the landscape
how to guide a ship up a significant
gradient
in the 16th century an invention came
along that revolutionized the science of
canals
the loch
in addition to its emblematic river the
sen since the 19th century paris has
boasted three lock canals with a total
length of 130 kilometers
the canal sandini the canal de lorc
and the shortest but most famous the
canal samarta
its nine locks allow boats to travel in
both directions and negotiate an
elevation of almost 26 metres
between the artificial watercourse and
the river
the waterfall at each of these locks is
something like three meters
or one story each lock acts like a boat
lift

lock chamber
