HISTORY OF THE DANUBE DELTA

I. Location, stretching

  Danube, springing from Germany, collecting tributaries from ten countries and across the four capitals, after a journey of 2860 miles, at the mouth to form a delta on the Black Sea.

  Reported in Romania, Danube Delta is located in SE country lirma shaped Greek letter "A" (the delta) and is limited to the SW of the bridge. Dobrogea, passing north across the border with Ukraine and the Black Sea's. Danube Delta is crossed by the parallel 45 ° N lat and long maridianul of 29 °. E

  Surface, together with Rasim-Sinoe lagoon complex is 5050 km, of which 732 km are in Ukraine.Delta itself has an area of 2540 km, an area of 40m annual increases, due to the 67 million tons of silt deposited by river.

II. Genesis, evolution, present and future

  The Delta, started in Quaternary glaciation vurniana in having two distinct phases:
 - A phase of marine regression caused when mainland shore was more withdrawn and have left the Danube arms visible in the current continental shelf canyons
 - A phase that followed a golf transgressions. Antipa issued haven hypothesis and continued Zencovici VP admits the presence of a bay by marine currents crossed by transverse ridges and turned into a haven. Danube has gathered this space, given a low of ~ 70 cm high. Calmatarea further led to the current issue.

  Seen from the hills of Tulcea, the Danube Delta is crossed by a green expanse of silver stripes.

  Delta is a plain in training, with an average altitude of 50 cm, consisting of: positive relief (ridges, and islands) and negative relief: the Danube arms, canals, brooks, marshes, swamps and lakes.

  Delta is 13% of land surface and is represented by:
River-banks, which accompany the Danube arms are oriented west-east direction, with heights of 0.5-5m
Maritime-oriented ridges on the north-south, is remarkable Letea with 124m altitude - maximum altitude delta Caraorman Saltings, Ivancea Dranov, etc..
Mainland banks, which represent remnants of land predeltaic: Chilia and Stipoc.

  Annual quantity of silt brought by the Danube, plus the remains of dead organisms, dust, wind, etc.. Will make the percentage of land to grow at the expense of negative relief.

III. Historico-geographical Certifications

  The first historical news about the Danube Delta has left us a Greek Herodotus, "father of history" describing the Persian fleet into Delta Darius, who had stayed after Histria (515-513 BC), Polibiu (sec. III - II BC) describes a space with sand banks between which arms were water, travel (c. BC) indicates that there were seven branches between islands, and resumed idea Pliny the Elder, Ptolemy, etc.. Testimony of living area there is the century II BC-AD.

  In sec. XV, Country Romanian and Moldova and Dobrogea lose Danube mouths as they have been conquered by the Ottoman Empire and thus, until the second half. Nineteenth century, the Delta was a "terra incognito." Detailed studies on the delta were by geographers Vaslan George Constantin Bratescu naturalist Grigore Antipa.
