Detailed Presentation

The Danube Delta began to be formed in Quaternary, in the icy era consisting of two distinct periods:
the continental period - produced by the marine regression, when the shore was very much withdrawn and the arms of the Danube launched visible canyons in what it is now the continental platform
the gulf period - that followed a transgression. The hypothesis about the coast issued by Grigore Antipa and confirmed by P. Zencovici, admits the presence of a gulf, isolated by the marine currents through transversal narrow reefs and which finally formed the bank.

The Danube clogged this surface in the conditions of a reduced tide of about 70 cm. The continuous clogging shaped the present aspect of the delta. "The place where a new land is being created". When the Danube Delta is seen from Tulcea Hills, it looks like a green surface crossed by silver stripes.

The Danube Delta is a plain, which is continuously being formed, it has an average altitude of 50 cm and it is made up of:
positive relief (narrow reefs, islands, drift woods)
negative relief (the Danube arms, channels, brooks, swamps, marshes and lakes).
The land of the delta represents 13% of its surface and it is made up of:
river narrow reefs that accompany the Danube arms and are oriented towards West-East with an altitude of 0.5-5 m.
marine narrow reefs oriented towards North-South; Letea is remarkable for its altitude of 124 m, the maximum altitude for the delta and also Caraorman, Dranov, Ivancea, Saraturile, etc.
continental narrow reefs that represent residuum from the land before the delta was formed: Chilia and Stipoc.

The quantity of alluvial deposits brought by the Danube every year, to which are added the residuum of the dead organisms, the eolian dust etc. will make the percent of land increase to the detriment of the negative relief.

Danube Delta, Romania

"General description"

Danube Delta is a natural paradise which spreads at the flow of the Danube in the Black Sea, after a long trip of 2860 km, starting in Black Forest Mountains in Germany.

The surface of Danube Delta grew with the centuries because of the mud that was brought by the Danube and formed a network of channels, lakes, islands, reed islets, tropical forests and sand dunes, which occupy now almost 5 640 km².

"Fauna and Flora"

This incredible not enough known territory hides 325 species of birds (it is the biggest pelican area in Europe). Here you can find 110 species of fish from sturgeons to carps, breams and perches; 36 of these species belong to the delta proper (the delta accounts 50 percent of the fresh-water fish production of Romania.). A variety of 1150 species of plants from lianas to water-lilies populate this area. No wonder that UNESCO declared this area as a "Biosphere Reservation".

P.S: everybody shows only pictures pelicans from Danube Delta. It is true, they are really spectacular birds, but there are more...i hope a picture with common Gulls, satisfies your curiosity;)

"People"

For 5000 years a small amount of people has been living here in full harmony with this extraordinary ecosystem, gaining its existence out of fishing, growing animals and harvesting reed. The villages, which can be accessed only by water, appear to be hardly touched by time; modern life doesn't have a too big influence here.

AleXFL's new Tulcea Page

I have been living in Tulcea for a while, and I moved to Florida three years ago. For those who love nature adventures, I strongly recommend a trip to Tulcea and Danube's Delta. Being in Everglades with my friend remembers me the best the feeling of Danube Delta. If you have more questions, don't hesitate to write me.
