How is Venice Italy different from New Orleans?

Answer 1

Venice is above sea level, built above a shallow body of water. New Orleans was built on dry land made by draining the swamps around a small area of higher ground. New Orleans is almost entirely below sea level.

The small islands of Venice Italy were mostly above mean sea level at high tide. As a defense measure, rivers were diverted through the lagoon to keep it free of sediment. To construct the city, foundations were built in the shallow lagoon between the islands. However, Venice is still susceptible to flooding by high tides in the Adriatic Sea.
