In XV-XVI century, hydraulic projects have prevented the Venetian lagoon to turn into a swamp by changing the meaning of the lagoon's natural evolution. Pumping the aquifers (underground rivers where the queen extract various unconsolidated materials (sand, mud) through various electrical pumps, since the nineteenth century the water level has risen considerably. Initially, many of the islands of the lagoon were mlastinose but due to program drainage have been given for housing (though many of them are artificial islands are actually some initial dune). Venice is the largest island in the lagoon and has an area of 5.17 km2.
