The Venetian Lagoon is a lagoon of the Adriatic Sea in which the city of Venice is situated. A lagoon is a body of comparatively shallow salt or Brackish water separated from the deeper Sea by a shallow or exposed sandbank, coral Venice ( Italian: Venezia, Venetian: Venesia or Venexia) is a city in Northern Italy, the capital of the Its name in the Venetian language has provided the international name for an enclosed, shallow embayment of saltwater. Venetian or Venetan is a Romance language spoken by over two million people mostly in the Veneto region of Italy. Headlands and bays are two related features of the coastal environment
The Venetian Lagoon stretches from the Sile in the north to the Brenta in the south, with a surface area of around 550 km². See River Sile for the river in Italy Síle is also a girl's name in Irish, usually anglicized as Sheila. It is around 8% land, including Venice itself and many smaller islands. Venice ( Italian: Venezia, Venetian: Venesia or Venexia) is a city in Northern Italy, the capital of the About 11% is permanently water, or canal as the network of dredged channels are called, while around 80% is mud flats, tidal shallows and salt marshes. Canals are artificial channels for water There are two types of canals water conveyance canals which are used for the conveyance and delivery of water and Waterways Mudflats (also tidal flats, tide flats, etc are coastal wetlands that form when mud is deposited by tides or rivers A salt marsh is a type of Marsh that is a transitional intertidal between land and salty or Brackish water (e The lagoon is the largest wetland on the Mediterranean Basin. A wetland is an area of Land consisting of Soil that is Saturated with Moisture, such as a Swamp, Marsh, or Bog The Mediterranean Basin refers to the lands around and surrounded by the Mediterranean Sea. 
It is connected to the Adriatic Sea by three inlets: Lido inlet, Malamocco inlet and Chioggia inlet. Venice 's Lido is an 11-mile (18 km long sandbar, home to about 20000 residents greatly augmented by the (mainly Italian tourists who move in every summer An inlet is a narrow body of water between islands or leading inland from a larger body of water often leading to an enclosed body of water such as a sound, bay, Chioggia ( Venetan: Cióxa, Latin: Clodia) is a coastal town and Comune of the Province of Venice in the Veneto Being at the end of a closed sea, the lagoon is subject to high variations in water level, the most extreme being the spring tides known as the acqua alta (Italian for "high waters"), which regularly flood much of Venice. Characteristics A tide is a repeated cycle of sea level changes in the following stages Over several hours the water rises or advances up a beach in the flood Acqua Alta is a phenomenon that regularly occurs in the city of Venice, Italy most commonly during high and spring tide.
The Lagoon of Venice is the most important survivor of a system of estuarine lagoons that in Roman times extended from Ravenna north to Trieste. An estuary is a semi-enclosed Coastal body of Water with one or more Rivers or Streams flowing into it and with a free connection to the open Ravenna is a City and Comune in the Emilia-Romagna region of Italy. Trieste (Trieste Slovene and Croatian: Trst; German: Triest) is a city and port in northeastern Italy very near to In the sixth century, the Lagoon gave security to Romanised people fleeing invaders (mostly the Huns). The 6th century is the period from 501 to 600 in accordance with the Julian calendar in the Christian / Common Era. The Huns were an early confederation of Central Asian equestrian nomads or semi-nomads with a Turkic core of aristocracy Later, it provided the conditions for the growth of the Venetian Republic and its maritime empire. The Most Serene Republic of Venice ((Serenìsima Repùblica Vèneta or Repùblica de Venesia Serenissima Repubblica It still provides a base for a seaport, the Venetian Arsenal and for fishing, as well as a limited amount of hunting and the newer industry of fish farming. ||-||-|-||-||-||-||-||-||-|} A port is a facility for receiving Ships and transferring cargo The Venetian Arsenal (Arsenale di Venezia is a Shipyard and naval depot that played a leading role in Venetian empire-building For the computer security term see Phishing. Fishing is the activity of catching Fish. Hunting is the practice of pursuing Animals for Food, Recreation, or Trade. Fish farming is the principal form of Aquaculture, while other methods may fall under Mariculture.
The Lagoon was formed about six to seven thousand years ago, when the marine transgression following the Ice Age flooded the upper Adriatic coastal plain. Torcello is a quiet and sparsely populated Island at the northern end of the Venetian Lagoon. An ice age is a period of long-term reduction in the Temperature of the Earth 's surface and atmosphere resulting in an expansion of continental Ice sheets  River sediments compensated for the sinking coastal plain, and coastwise drift from the mouth of the Po tended to close tidal inlets. The Po ( Latin: Padus, Po Ligurian: Bo, Greek: Eridanus) is a river that flows 652 km(405 miles (682 km by considering Venetiuan hydraulic projects to prevent the lagoon from turning into a marsh reversed the natural evolution of the Lagoon in the fifteenth and sixteenth centuries. Pumping of aquifers since the nineteenth century has increased subsidence. An aquifer is an underground layer of Water -bearing Permeable rock or unconsolidated materials ( Gravel, Sand, Silt, or Clay Thus the present aspect of the Lagoon is due to human intervention. Originally many of the Lagoon’s islands were marshy, but a gradual programme of drainage rendered them habitable. Many of the smaller islands are entirely artificial, while some areas around the seaport of the Mestre are also reclaimed islands. Mestre' is a town in Veneto, northern Italy, a Frazione of the Comune of Venice. The remaining islands are essentially dunes, including those of the coastal strip (Lido, Pellestrina and Treporti). Venice 's Lido is an 11-mile (18 km long sandbar, home to about 20000 residents greatly augmented by the (mainly Italian tourists who move in every summer Pellestrina is an Island forming a barrier between the southern Venetian Lagoon and the Adriatic Sea, lying south west of the Lido.
