Danube

Danube - sacred river of the Slavs. It is often mentioned in songs, fairy tales, legends and traditions of all Slavic peoples. In addition, the history of the Celts, the Thracians, Illyrians and Greeks associated with the history of the Danube. In ancient times the Greeks called the Danube as well as the Thracians, who lived off the coast of the river - Istres. It was only later, in Roman times across the river to fix its current name, which is pronounced and written as Danubio. In the 7 th century BC, Greeks founded south of the Delta colony and named it Istria. The ancients sought source of the river beginning at Riphaeus mountains. Then, in the far north, and later the Celts in the country in the Hercynian forest. But already in 1915 BC in the reign of Guibert were installed the true origins of the Danube: it begins on the array is now called the Black Forest two sources at an altitude of 1 kilometer. Since the reign of Augustus the Danube became the border of the Roman state with. Northern barbarians. The length of the Danube River is 2850 kilometers, with a catchment area - 817 thousand square kilometers. From the origins of the Danube flows along the edge of the Bavarian highlands, and then between the Bohemian massif and the northern slopes of the Eastern Alps. In its current almost to Vienna, the Danube flows through undulating hills and plateaus, with elevations over 200 meters. The plot of the river to Vienna is considered the upper course of the Danube. This is where the river receives a large number of tributaries. Chief among them - Iller, Lech, Isar, Inn - flow from the Alps and fed by glaciers. These inflows determine the features of the regime of the upper Danube, which is a typical alpine river with a maximum flow rate in the first half of the summer. Summer Alpine flood passed down the stream and there throughout the middle reaches of rivers. Middle reaches of the Danube starts from Vienna. The mid-Danube crosses the Lowlands and here receives its largest tributaries, from the Alps descend Raba, Drava with the influx of Moore, Sava, and from the Carpathians - Nitra, Hron, and the largest tributary of the Danube - Tisza. In winter, the lowlands are frost and snow, while summers are hot, especially in the second half. Danube freezes in the winter months, although not every year, and not for a long period. In the spring a maximum water level in vsyazi with the melting snow. This maximum extends over the first half of summer, as amplified Alpine flood. In the second half of the summer under the influence of strong evaporation reduces the water level and the Danube even grows shallow. Autumn comes a new level rise due to rains. The subsequent section of the Danube flow passes through the Carpathian Mountains, where the river forms a narrow valley called the Iron Gate. After leaving the Iron Gate Danube flows through Nizhnedunayskoy lowlands to the confluence of the Black Sea, receiving tributaries flowing down from the Carpathians and the Balkans. The largest of them - Carpathian River: Ault, Ialomita, Siret. In lowland floodplain of the Danube, known as the Baltic, is very wide. The main river channel is accompanied by a mass of channels and oxbow lakes. At the confluence of the Black Sea in the delta of the Danube channel splits into branches, called Girlie. Just an average, Sulina arm navigable. The other two are not available for the courts because of the numerous shoals and sand bars.
