The Venetian lagoon: photos, description (Laguna di Venezia)

Geographically Venice lagoon is a closed Bay of the Adriatic sea, on the shore of which is Venice. It stretches from the river sile in the North to the Brenta in the South. The total area of the lagoon is about 550 sq. km, About 8% of the lagoon area is a small island and, in fact, Venice, and 11% is permanently covered by water. The remainder, a large part of the lagoon is about 80% - is silted plains (called watts), tidal shoals and salt marshes. The entire Venetian lagoon is the largest wetland of the Mediterranean basin.

The Adriatic sea and Laguna are connected by three small inlets of Lido, Malamocco and Khodja. In the spring the water level in the lagoon rises significantly, causing floods, regularly zataplivaja Venice, is a phenomenon in Italian language is called "Aqua Alta" (high water).

The Venetian lagoon is the most important surviving part of a system of estuarine lagoons that in Roman times extended from Ravenna to Trieste. It was on its shores in the 6th century, the Romans took refuge from the warlike Huns. Later, the geographical location of the lagoon contributed to the formation and flourishing of the powerful Venetian Republic, the possession of which extends far beyond the Adriatic sea. Today on the shore of the Venetian lagoon there is a major sea port and the Venetian Arsenal (Doc), and in recent years has been the development of fish farming.

It is necessary to tell, that the Venetian lagoon was formed 6-7 thousand years ago, when the result of the occurrence of sea to land after the Ice age had flooded part of the Adriatic coastal plain. River sediments gradually "offset" disappeared under the water, land, and sediments brought from the mouth of the river Po, created a sandbar. Current look of the lagoon - is the result of human activity. In the 15-16-th centuries various hydraulic projects of the Venetians, in order to prevent the conversion of the lagoon into a swamp, completely changed her natural evolution. Experiments with aquifer, which began in the 19th century has increased subsidence. Initially, most of the lagoon Islands were marshy, but a consistent projects according to their drainage made them habitable. Some of the smaller Islands are entirely artificial (including the area around the sea port of Mestre). The remaining, in fact, represent dunes - coastal strip of the Lido, Treporti and Pellestrina. The largest Islands of the Venetian lagoon are Venice, Sant'erasmo, Murano, Khodja, Giudecca, Mazzorbo, Torcello, Sant'elena, La Certosa Burano, Tronchetto, Sacca of Fisola, San Michele, Sakka Sessola and Santa Cristina.
