Program Overview
|
|
|
Venice, Italy, faces threats to its art, architecture, and history
from an increasing frequency of floods. NOVA explores the debate
about how to best control these high water occurrences.
The program:
-
recalls the 1966 flood that deluged Venice, Italy, for 15 hours.
-
describes the geography of Venice that makes it vulnerable to
flooding.
-
reviews reasons for present-day flooding, including storm
surges, mean sea level rise, and the sinking of Venice.
-
chronicles measures taken in The Netherlands and London,
England, to prevent flooding in those areas.
-
introduces the design currently under development—a series
of mobile floodgates situated at the three lagoon entrances that
would be raised with compressed air when the city is threatened
by extremely high tides.
-
presents both sides of the active debate concerning the
floodgates, including the key issue of how often the gates would
be deployed and what effects the closings would have on the
lagoon's health.
