Bosut River
The Bosut is a 186-kilometer-long left tributary of the Sava river in eastern Croatia and northwestern Serbia. It is also known as the eighth-longest river in Croatia. It gets its name from the Indo-European word *bhogj, which means "to flow." The same root can be found in the hydronym "Bosna."
The Bosut river begins as the Biđ river in central Slavonia, on the southern slopes of the Dilj mountain, northwest of Slavonski Brod. It has no major communities and flows generally to the northeast, while several larger villages like Donji Andrijevci, Vrpolje, and Strizivojna are nearby. Biđ is 66 kilometers (41 miles) long.
The Bosut river is notable for being meandering and slow, with a relatively little incline in its basin - less than 10 meters from Vinkovci to its mouth. Bosut is known as "the river that flows backward" because, when there are strong winds and the water is moving slowly, it appears as if the water is flowing backward.
