(in German, Drau), a river in Europe; a right tributary of the Danube. Length, 720 km; basin area, about 40,000 sq km. It rises in Italy, in the Carnic Alps. In its upper course (in Austria) it crosses the Klagenfurt depression, cuts through the southern spurs of the Eastern Alps, and flows out onto the Hungarian (Danube) Plain, over which it flows to its mouth in Yugoslavia; in some sections it serves as the border between Yugoslavia and Hungary. Its main tributaries are the Gurk and Mura on the left and the Gail and Karasica on the right. High water is in spring; there are summer and fall floods (inundations are common), and low water is in the winter. The average water discharge at the mouth is 610 m3/sec; the greatest discharge is more than 2,500 m3/sec. There is a network of large hydroelectric power plants in Austria and Yugoslavia. The river is navigable up to the city of Villach in Austria (650 km from the mouth). The cities of Villach (Austria) and Maribor, Ptuj, Varazdin, and Osijek (Yugoslavia) are located on the Drava.
