Course
The Sava is located in the Southeast Europe, flowing through Slovenia, Croatia, Serbia and along Bosnia-Herzegovina border. Total length of the Sava River is 990 kilometres (615 miles), including the 45-kilometre (28 mi) Sava Dolinka and the 945-kilometre (587 mi) Sava proper. As a right tributary of the Danube, the river belongs to the Black Sea drainage basin. The Sava River is the third longest tributary of the Danube, slightly shorter than the 966-kilometre (600 mi) Tisza and the 950-kilometre (590 mi) Prut—the Danube's two longest tributaries—when the Sava Dolinka headwater is excluded from its course. It is also the largest tributary of the Danube by discharge. The river course is sometimes used to describe the northern boundary of the Balkans, and the southern border of the Central Europe. Before the breakup of Yugoslavia in 1991, the river was located completely inside Yugoslav borders and it was the longest river with its entire course within the country.
