Danube Delta

Danube Delta (3446 km ²), located largely in Dobrogea, Romania, and partly in Ukraine, is the largest and best preserved of European deltas.

Delta entered into the UNESCO World Heritage in 1991, is classified as a national biosphere reserve in Romania as a national park in the IUCN international taxonomy.

 The Danube delta is bounded on the south-west of Dobrogea Plateau, north forms the border with Ukraine, and flows east into the Black Sea. The Danube Delta is crossed by parallel 45 ° N and longitude 29 ° longitude E. Delta deal with Razim - Sinoe 5050 km ², of which 732 km ² are in Ukraine, Delta Romanian being awarded to an area of 2540 km ². Due to the 67 million tons of silt to the Danube Delta is increasing annually by approx. 40 meters.

The Danube has reached the Patlageanca bifurcates into two arms, Chilia north and south of Tulcea arm, arm then fog-Saint George, breaks arm in arm Sulina and Saint Gheorghe.

Chilia, forms the border with Ukraine, and his course of carrying on a length of 104 km ², 60% of the Danube waters and alluvium.

Sulina arm is located in the heart of the Delta, and unlike Chile, has a straight course, always maintained dredged for navigation and maritime vessels. It has a length of 71 km and carries 18% of the Danube water.

Course arm of St. George is facing southeast, and conducted on 112 km, carrying 22% of the flow of the Danube. The islands form the estuary delta Sacalin considered a top secondary.

Delta (except delta secondary Chilia) is traditionally part of Dobrogea, but in Antiquity and Middle Ages, the coast is much more to the west (between Chile and Murighiol Old Strabo's time, between Lake and Periprava Dranov the Byzantine era ), so that historical maps are including all Delta Dobrogea current geomorphological are false.
