Drava
Summary
The Drava or Drave (Drau, ˈdʁaʊ; Drava ˈdɾàːʋa; Drava drǎːʋa; Dráva ˈdraːvɒ; Drava ˈdraːva), historically known as the Dravis or Dravus, is a river in southern Central Europe. With a length of 710 km, 724 km including the Sextner Bach source, it is the fifth or sixth longest tributary of the Danube, after the Tisza, Sava, Prut, Mureș and perhaps Siret. The Drava drains an area of about 40 154 km2. Its mean annual discharge is seasonally 500 m3/s to 670 m3/s. Its source is near the market town of Innichen, in the Puster Valley of South Tyrol, Italy. The river flows eastwards through East Tyrol and Carinthia in Austria into the Styria region of Slovenia. It then turns southeast, passing through northern Croatia and, after merging with its main tributary Mur, forms most of the border between Croatia and Hungary, before it joins the Danube near Osijek.
In ancient times the river was known as Dravus or Draus in Latin, and in Greek as Δράος and Δράβος. Medieval attestations of the name include Dravis ( AD 670), Drauva (in 799), Drauus (in 811), Trauum (in 1091), and Trah (in 1136). The name is pre-Roman and pre-Celtic, but probably of Indo-European origin, from the root *dreu̯- 'flow'. The river gives its name to the dravite species of tourmaline.
The Carpis (Greek: Κάρπίς) was a river which, according to Herodotus, flowed from the upper country of the Ombricans northward into the Ister (Danube), whence it has been supposed that this river is the same as the Dravus.
The Drava (along with one of its tributaries, the Slizza) and the Spöl are the only two rivers originating in Italy that belong to the Danube drainage basin. Its main left tributaries (from the north) are the Isel (contributes 39 m3/s), the Möll (25 m3/s), the Lieser (22 m3/s), the Gurk (30 m3/s) and the Lavant (12 m3/s) in Austria, and the Mur (166 m3/s) near Legrad at the Croatian–Hungarian border. Its main right tributaries (from the south) are the Gail (45 m3/s) in Austria, the Meža (12 m3/s) and Dravinja (11 m3/s) in Slovenia, and the Bednja (? m3/s) in Croatia.
