Question

How deep is the water that Venice, Italy is floating on?

Answer 1

Venice  is surrounded by the Adriatic Sea,  which has different levels in different points.  It is actually about 1 foot "lower"  than it was about 200 years ago...which is why authorities are worrying that it is "sinking".    last year about 1/3rd of the year,  water sloshed into St Mark's Square....a sign that  more of the city is covered during more of the year.  Obviously the beautiful buildings will begin to be severly affected in terms of beauty and structural damage.  the average canals are 12 meters deep,  and as you know,  a meter is about 3 feet.

Answer 2

First of all you must have clear that Venice is not floating on the water and it's not surrounded by the Adriatic sea. Venice has been built on the dryland and it's surrounded by the lagoon (laguna).Thus Venice has not a measure of water deepness since it's not under the level.However now it's suffering of a certain sinking that has been evidenced in the last centuries by effect of the flooding; this regularly happens, mainly in winter season, when the lagoon receives ,depending on the tides level, the water from the Adriatic Sea.This effect is called "acqua alta" (high water) and its spectacular effects are mainly visible on the Saint Mark square. The level of this flooding goes from abt. 60 cms. (2 feet) upto 1,20 meters (4 feet) and previous Italian Government has started to build the Mose that's a kind of movable d**e to limit the effect of the flooding that year by year are becoming of an higher level with the risk to compromise the Venice's building's stability.
