About the Danube Delta

The Danube springs in the Black Forest, Germany and has tributaries from ten countries: Germany – Austria – Slovakia – Hungary – Croatia – Serbia – Romania – Bulgaria- Rep Moldova – Ukraine. It crosses four capitals: Vienna, capital of Austria; Bratislava, capital of Slovakia; Budapest, capital of  Hungary; Belgrade, capital of Serbia. After a route of 2860 km, it forms a delta at the mouth of the Black Sea. The Danube Delta is situated in the South – East of Romania, having the form of the Greek letter “A” (delta). It is limited to the South West by Dobrogea Plateau, at  North, crosses the border with Ukraine, and at East with the Black Sea. Its surface, along with the lagoon complex Razim – Sinoe, is of 5050 km. 732 km are on Ukranian territory.

The Danube Delta has an area of 2540 km, which grows annually with 40 m due to the 67 million tons of silt deposited by the river.

The three arms of the Danube are:

Chilia: the youngest and longest (120 km) with many branches and islands. On this arm, it used to be practiced river navigations, most important ports being Izmail and Vilcov (Ukraine).

Sulina: preferred for maritime navigation. Because of silt deposits, a channel which progresses gradually in the sea was built for protecting the navigation.

St. Gheorghe: the southernmost and oldest branch with a length of 109 km.
