Venice is located in northeastern Italy, in the Veneto region. The city is situated on a group of 118 small islands that are separated by canals and linked by 438 bridges. The historic center of Venice is divided into six districts, or sestieri, which are named [[Cannaregio]], Castello, [[Dorsoduro]], San Marco, San Polo, and Santa Croce.

Venice sits atop alluvial silt washed into the sea by the rivers flowing eastward from the Alps across the [[Veneto]] plain, with the silt being stretched into long banks, or ''lidi'', by the action of the current flowing around the head of the [[Adriatic Sea]] from east to west.<ref>{{EB1911 |noprescript=1 |wstitle=Venice |volume=27 |page=995}}</ref>

=== Subsidence ===
[[Subsidence]], the gradual lowering of the surface of Venice, has contributed – along with other factors – to the seasonal ''[[Acqua alta]]'' ("high water") when the city's lowest lying surfaces may be covered at high tide.

==== Building foundations ====
Those fleeing barbarian invasions who found refuge on the sandy islands of Torcello, Iesolo, and Malamocco, in this coastal lagoon, learned to build by driving closely spaced [[Deep foundation|piles]] consisting of the trunks of [[alder]] trees, a wood noted for its water resistance, into the mud and sand,<ref>{{cite web |url=http://www.treesforlife.org.uk/forest/mythfolk/alder.html |title=Mythology and Folklore of the Alder |last=Kendall |first=Paul |date=25 August 2010 |website=[[Trees for Life (Scotland)|Trees for Life]] |access-date=6 August 2011 |url-status=dead |archive-url=https://web.archive.org/web/20110805135339/http://www.treesforlife.org.uk/forest/mythfolk/alder.html |archive-date=5 August 2011}}</ref><ref>{{cite web |url=http://www.cvni.org/treenursery/trees/alder |title=Alder – Alnus glutinosa |publisher=Conservation Volunteers Northern Ireland |access-date=6 August 2011}}</ref> until they reached a much harder layer of compressed [[clay]].

Between autumn and early spring, the city is often threatened by flood [[tide]]s pushing in from the [[Adriatic Sea|Adriatic]]. Six hundred years ago, Venetians protected themselves from land-based attacks by diverting all the major rivers flowing into the lagoon and thus preventing sediment from filling the area around the city.<ref>{{cite web |url=https://www.pbs.org/wgbh/nova/venice/sieg_nf.html |title=NOVA {{pipe}} Sinking City of Venice {{pipe}} Venice Under Siege (non-Flash) {{pipe}} PBS |website=PBS}}</ref> This created an ever-deeper lagoon environment. Additionally, the lowest part of Venice, [[St Mark's Basilica]], is only {{convert|64|cm|in}} above sea level, and one of the most flood-prone parts of the city.<ref>{{Cite web |last=Brown |first=Hannah |date=9 August 2021 |title=Venice floods: Watch tourists wade through knee-deep water |url=https://www.euronews.com/travel/2021/08/09/venice-is-flooding-again-watch-tourists-wade-through-knee-deep-water |access-date=15 November 2021 |website=[[euronews]] |language=en}}</ref>

In 1604, to defray the cost of flood relief, Venice introduced what could be considered the first example of a stamp tax.<ref>{{cite web |last1=Iwu |first1=Rita |title=Stamp Tax |url=https://www.ibtimes.com/terms/s/stamp-tax |website=[[International Business Times]] |access-date=26 October 2022 |language=en |date=19 May 2021}}</ref> When the revenue fell short of expectations in 1608, Venice introduced [[Postal stationery|paper]], with the superscription "AQ" and imprinted instructions, which was to be used for "letters to officials". At first, this was to be a temporary tax, but it remained in effect until the fall of the Republic in 1797. Shortly after the introduction of the tax, Spain produced similar paper for general taxation purposes, and the practice spread to other countries.

During the 20th century, when many [[artesian well]]s were sunk into the periphery of the lagoon to draw water for local industry, Venice began to [[subsidence|subside]]. It was realized that extraction of water from the [[aquifer]] was the cause. The sinking has slowed markedly since artesian wells were banned in the 1960s. However, the city is still threatened by more frequent low-level floods – the ''[[Acqua alta]]'', that rise to a height of several centimetres over its [[quay]]s – regularly following certain tides. In many old houses, staircases once used to unload goods are now flooded, rendering the former ground floor uninhabitable.{{citation needed|date=February 2020}}

Studies indicate that the city continues sinking at a relatively slow rate of 1–2{{nbsp}}mm per year;<ref>{{cite report |last1=Bock |first1=Y. |display-authors=etal |title=Recent Subsidence of the Venice Lagoon from Continuous GPS and Interferometric Synthetic Aperture Radar |url=http://sciences.blogs.liberation.fr/files/venise-senfonce.pdf |date=2012 |url-status=dead |archive-url=https://web.archive.org/web/20160304124453/http://sciences.blogs.liberation.fr/files/venise-senfonce.pdf |archive-date=4 March 2016 |access-date=23 April 2019}}</ref><ref>{{cite web |url=https://www.comune.venezia.it/it/content/la-subsidenza-e-leustatismo |title=La subsidenza e l'eustatismo |language=it, en |trans-title=Subsidence and eustatism |date=25 March 2022 |website=City of Venice |archive-url=https://web.archive.org/web/20230506212333/https://www.comune.venezia.it/it/content/la-subsidenza-e-leustatismo |archive-date=6 May 2023 |url-status=live}}</ref> therefore, the state of alert has not been revoked.

In May 2003, Italian Prime Minister [[Silvio Berlusconi]] inaugurated the [[MOSE Project]] ({{Langx|it|Modulo Sperimentale Elettromeccanico}}), an experimental model for evaluating the performance of hollow floatable gates, expected to be completed by the end of 2025;<ref>{{cite web |url=https://www.bbc.com/future/article/20220927-italys-plan-to-save-venice-from-sinking |title=Italy's plan to save Venice from sinking |website=BBC |last=Phelan |first=Joseph |date=28 September 2022 |access-date=30 September 2022}}</ref> the idea is to fix a series of 78 hollow [[pontoon (boat)|pontoons]] to the sea bed across the three entrances to the lagoon.

According to a spokesman for the National Trust of Italy ([[Fondo Ambiente Italiano]]):<ref>{{cite web |last=Gerard-Sharp |first=Lisa |url=http://www.natgeotraveller.co.uk/destinations/europe/italy/is-venice-going-under/ |title=Is Venice going under? |date=16 August 2016 |website=National Geographic}}</ref>

<blockquote>
Mose is a pharaonic project that should have cost €800m [£675m] but will cost at least €7bn [£6bn]. If the barriers are closed at only 90 cm of high water, most of St Mark's will be flooded anyway; but if closed at very high levels only, then people will wonder at the logic of spending such sums on something that didn't solve the problem. And pressure will come from the cruise ships to keep the gates open.

[[Henk Ovink]], an expert on flooding, told [[CNN]] that, while environmental factors are part of the problem, "historic floods in Venice are not only a result of the climate crisis but poor infrastructure and mismanagement".<ref>{{cite news |url=https://www.cnn.com/videos/tv/2019/11/19/henk-ovink-amanpour-climate-crisis-water-venice-floods.cnn |title=Historic floods in Venice a 'man-made disaster' |date=11 July 2007 |work=CNN |access-date=19 November 2019}}</ref>

=== Climate ===
According to the [[Köppen climate classification]], Venice has a mid-latitude, four season [[humid subtropical climate]] (''Cfa''), with cool, damp winters and warm, humid summers. The 24-hour average temperature in January is {{convert|3.3|C|F|1}}, and for July this figure is {{convert|23.0|C|F|1}}. Precipitation is spread relatively evenly throughout the year, and averages {{convert|748|mm|in}}; snow is not uncommon between late November and early March. During the most severe winters, the canals and parts of the lagoon can freeze, but with the warming trend of the past 30–40 years, the occurrence has become rarer.<ref>{{cite web |last=Sibilla |first=Marco |title=Laguna ghiacciata |trans-title=Frozen lagoon |url=http://www.meteovenezia.net/laguna-ghiacciata.html |website=Meteo Venezia |language=it |access-date=2 March 2020}}</ref>
