The lagoon of Venice is the largest of the Mediterranean Sea, facing the North Adriatic Sea. It is about 55km2 wide and 1,5 m average deep. The astronomic tide maximum excursion is about ± 50 cm over the mean sea level. Tides force a water flush in the lagoon, carrying inside oxygenated and expelling de-oxygenated water, two times per day. This “breath” is essential to biological life and to...
