The Danube Delta is the second largest river delta in Europe, after the Volga River Delta, and is the most preserved on the continent.
The largest part of the Danube Delta in Romenia is located (Tulcea Province), while the northern part is located on the left bank of the Chilean arm, in Ukraine (Odessa Oblast).
The approximate surface is 4,152 km ², of which 3,446 km ² are in Romenia, if one of the extensive lakes is in Razm-Sineu (1,015 km ² of which 865 km ² are the surface of the water), which is located to the south of the proper delta, but Associated with geology and the environment (for its combined lands it is part of world heritage sites), the total area of ​​the Danube Delta reaches 5,165 km ².

The second largest river delta in Europe

The modern Danube Delta began after 4,000 BC formation in the Black Sea bay, when the sea level rose to its current level, as the river was initially built as a delta with a sand barrier that blocked the Danube Bay.

On filling the bay with sediments, the delta progressed outside the estuary that prevented the barrier after 3,500 BC building several successive lobes: St. George I (3,500-1,600 BC), and Solina (1,600-0 BC), St. George II (0 BC to the present) and Chile or Kela (1600 AD to the present).
Livio Geologist Giosan said that much of the silt in the delta and the large expansion of its surface area in the form of lobes resulted from soil erosion associated with deforestation in the Danube basin during the first and second millennia of the New York Times.
