Corinth
Canal
The Corinth Canal is a canal that connects the Gulf
of Corinth with the Saronic Gulf in the Aegean Sea.
It cuts through the narrow Isthmus of Corinth and separates the
Peloponnesian peninsula from the Greek mainland and therefore
effectively making the former an island. The canal is 6.3 kilometre
in length and was built between 1881 and 1893.
Tech. inf
The Canal cuts the Isthmus of Corinth in a straight line 6346 m.
long. Canal width is 24.6 m. at sea level and 21.3 m. at bottom
level. Depth range is from 7.5 to 8 meters. Twelve million cubic
meters of earth had to be removed to cut out the entire
passage.
Geology
The rock formations in the flanks of the Corinth Canal are not
uniform throughout. There are several geologic fissures which run
in east-west direction at a vertical angle to the canal axis. These
geologic features were responsible for a number of major landslides
into the Canal The canal was cut through heavily faulted
sedimentary rock in an active seismic zone.
Between 1893 and 1940, it was closed a total of four years for
maintenance and to stabilize the walls. In 1923 alone, 41,000 cubic
meters of material fell into the canal, which required two years to
clear it out.
History
Several rulers in antiquity dreamt of cutting a canal through the
Isthmus. The first to propose such an undertaking was the tyrant
Periander in the 7th century BC. He abandoned the project due to
technical difficulties, and instead constructed a simpler and less
costly overland portage road, named Diolkos. According to another
theory, Periander feared that a canal would have robbed Corinth of
its dominating role as entrepot for goods. Remnants of the Diolkos
still exist next to the modern canal.
Achievement
The Corinth Canal is considered a great technical achievement for
its time. It saves the 400 kilometres long journey around the
Peloponnesus for smaller ships, but since it is only 21 metres wide
it is too narrow for modern ocean freighters. The canal is nowadays
mostly used by tourist ships; 11,000 ships per year travel through
the waterway. The depth of the canal is 8 metres at low water. At
each end of the canal, seashore roads cross using submersible
bridges that are lowered to the canal bottom to allow maritime
traffic to pass.
