![]() There are also the delicate white-water lilies, the muse of the countless paintings by Monet. The unique flora of the Danube’s environment includes the somewhat smaller than other oak species - the pedunculate oaks, featuring a full-head of widespread leafy branches. Few Euryhaline fish species such as the European seabass, mullet, etc are found in lower parts of the river and the Danube Delta. Some of the notable fish species that are found in the Danube River basin include pike, Wels catfish, tench, zander, burbot, sturgeon, salmon, trout, etc. Other endangered species include Kingfishers, who reach their sexual maturity at the age of 1 and only live 2 years, and the professional swimmers but timid European pond turtles that get trapped in fishing weirs and drown. These animals are known for the construction of labyrinths of dams and canals, which other animals may occupy. As a result, the Alps and Carpathians-collected waters of its right-bank tributaries take up over half and up to two-thirds of the Danube basins.Īnother inhabitant of the river, the beaver prefers the calmer waters with rich aquatic vegetation. The naturally uneven drainage accommodates the massive dispel of water. km below the Sava and the Tisza confluences, running from the source to the Hungarian Gates. km from the Hungarian Gates Gorge to the Iron Gate in the Southern Romanian Carpathians (after joining with the Drava), and 590,000 sq. km from the Iron Gate to the Black Sea estuary, 210,000 sq. Over 30 of the densest and deepest tributaries are navigable by ships. km Danube’s drainage basin, is necessary for the network of 300 tributaries. The first third of the riverbanks are uniformly low fields, peat, and marshland, while most picturesque valley, reminiscent of a canyon, is located between Ingolstadt and Regensburg. To the north of the source, are the Swabian and the Franconian mountains, while the south opens up in a large Bavarian Plateau, thickly laden with river deposits from the river’s numerous Alpine tributaries. The Danube sources from two small streams of Breg and Brigach in the eastern slopes of the German Black Forest mountains, uniting in the Donaueschingen to give the river its narrow and rocky start. In some parts, especially in the stretches between Bratislava and Komárno and in the Sulina Channel, the distribution of the deposit is so intense, that draglines are constantly clearing the depths for navigating ships. Shoals, or dense groups of fish, depend on the concentration of deposits flowing through that part of the river. Similar to the virtually silt-free water within its reservoirs, the clean water flowing out of dams, only picks up silt deposits while eroding the banks of the river further downstream.Īlmost all of the solid particles found in the Danube are quartz grains. Containing year-round low organic matter content, its highest mineral content is during the months of winter. New, natural, and human-made dams and dykes alter the courses of the river runoff. The water levels begin to dwindle noticeably in October, as a result of the characteristically dry summers and autumns of the lower plains. The longest runoff occurs in the middle basins, once, when the upper course runoff makes its peak in June, and locally, from the early spring rains and the melting of snow in the plains, in April. Similar to its alpine tributaries, the upper Danube maximum runoff is set for June, while the lowest is in winter. The river is broken down into three distinctive sections by its physical characteristics. The well-known Austrian composer - Johann Strauss the Younger wrote the ‘An der schönen, blauen Donau’ (“The Blue Danube”), a famous waltz in 1867, which has become the symbol of imperial Vienna. Its significance is widely commemorated through Greek legends, Romanian songs, and even, modern novels. In the countries of Germany and Austria it is known as Donau in Slovakia and Ukraine as Dunaj in Hungary as Duna as Dunav in Croatia, Serbia, and Bulgaria and in Romania as Dunărea, ![]() ![]() The river is known by various names in the countries where it flows through. ![]() The Danube River ultimately drains into the Black Sea via the Danube Delta. ![]() The river passes through 10 European nations of Germany, Austria, Hungary, Serbia, Bulgaria, Croatia, Slovakia, Moldova, Ukraine, and Romania. It flows for 2,850km, sourcing from the confluence of Brigach and Breg rivers, close to the German town of Donaueschingen in the Black Forest region of Germany. One of Europe’s most significant shipping routes today and a major determinant in the settlement patterns and political evolution of Central and South-eastern Europe, the Danube River is the second-longest river of the European continent, after the Russian Volga River. ![]()
