The Tisza or Tisa is one of the main rivers of Central Europe. Once, it was called "The most Hungarian river" because it flowed entirely within Hungary. Today, it crosses several national borders. The Tisza begins near Rakhiv in Ukraine, at the confluence of the White Tisa and Black Tisa (the former springs in the Chornohora mountains; the latter in the Gorgany range). From there, the Tisza flows west, roughly following Ukraine's borders with Romania, then Hungary, and finally Serbia. It enters Hungary at Tiszabecs. It traverses Hungary from north to south. A few kilometers south of the Hungarian city of Szeged, it enters Serbia. Finally, it joins the Danube near the village of Novi Slankamen in Vojvodina, Serbia. The Tisza drains an area of about and has a length of —the biggest catchment and length of Danube's tributaries.〔 Its mean annual discharge is . It contributes about 13% of the Danube's total runoff.〔 Names for the river, in the countries through which it flows: *(ルーマニア語、モルドバ語():Tisa); *(ウクライナ語:Тиса) (); *(スロバキア語:Tisa) (); *(ハンガリー語:Tisza) (); *(セルビア語:Тиса, Tisa) (). The river was known as ''Tisia'' in antiquity; other ancient names for it included ''Tissus'' (in latin) and ''Pathissus'' (Πάθισσος in ancient greek), (Pliny, ''Naturalis historia'', 4.25). It may be referred to as the ''Theiss'' ((ドイツ語:Theiß)) in older English references, after the German name for the river. It is known as ''Tibisco'' in Italian, and in older French references (as for instance in relation to the naval battles on the Danube between the Turks and the German Empire in the 17th and 18th centuries) it is often referred to as the ''Tibisque''. Attila the Hun is said to have been buried under a diverted section of the river Tisza. ==Regulation== The length of the Tisza in Hungary used to be 1419 km. It flowed through the Great Hungarian Plain, which is one of the largest flat areas in central Europe. Since plains can cause a river to flow very slowly, the Tisza used to follow a path with many curves and turns, which led to many large floods in the area. After several small-scale attempts, István Széchenyi organised the "regulation of the Tisza" ((ハンガリー語:a Tisza szabályozása)) which started on August 27, 1846 and substantially ended in 1880. The new length of the river in Hungary was 966 km (1358 km total), with 589 km of "dead channels" and 136 km of new riverbed.The resultant length of the flood-protected river comprises 2,940 km (out of 4,220 km of all Hungarian protected rivers). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tisza」の詳細全文を読む スポンサード リンク
