the ‘natural modes’ of the basin – in
a similar way to sound waves in a
musical instrument, where a particular
frequency is produced by a given
length of string or air column. This
phenomenon is called resonance.
In oceanography, there is an additional
phenomenon known as seiche
(pronounced ‘saysh’, from an old
French word meaning ‘to sway’). This
is when a standing wave is established
in a semi-enclosed body of
water, which moves from side to side
as a mass – rather like tides. For example,
the Adriatic seiche, which has
a period of 21.5 hours, is associated
with serious floods in Venice, Italy.
Other naturally occurring examples
of seiches have been observed in Lake
Geneva and in the Baltic Sea.
