The Bosut originates as the Biđ river in central Slavoniaregion, on the southern slopes of the Dilj mountain, northwest of the city ofSlavonski Brod. Generally flowing to the northeast, it has no major settlements though some larger villages are in the vicinity of the river. Biđ is long. The Berava is a small river that rises south of Velika Kopanica, meanders eastwards near Gundinci and Babina Greda, and turns north near Gradište, south of Cerna.
Downstream of Cerna
In the village of Cerna, the Biđ receives the river Berava from the south and from this point it is known as the Bosut. Some maps though, indicate that name Bosut is used before the river reaches Cerna, and some other apply the name also for the lowest part of the Berava's course, between Gradište and Cerna. Turning north from there, the river flows into the region of Syrmia, and the villages of Andrijaševci and Rokovci, reaching the biggest settlement on its course, the city of Vinkovci. From there, the rivers turns to the southeast, which is the direction it will follow for the rest of its course, except for a large U-bend south of Vinkovci. It passes through Kunjevci, Nijemci, Podgrađe, Apševci and Lipovac, where it receives the river Spačva from the right, and after the flow of 151 km through Croatia, crosses the Serbian border. The Bosut enters Serbia at the village of Batrovci and flows through the southwesternmost part of the province of Vojvodina. It continues through the villages of Morović and Višnjićevo, makes a turn north of Sremska Rača and, after 28 km in Serbia, empties into the Sava at the village of Bosut. A Slezen pond, near Morović, is located in the river's valley.
Characteristics
The Bosut belongs tothe Black Sea drainage basin, with its own drainage area of . For some 40 km it is navigable for smaller vessels. The river is known as meandering and extremely slow, and it has a very small inclination in its basin - less than 10 m from Vinkovci until its mouth. Bosut is known for a phenomenon of being 'the river that flows backwards', because sometimes, with strong winds and being so slow, it appears as if the water is flowing backwards. The whole valley of the Biđ-Bosut is actually an old, fossil river bed of the Sava. It is also known as a region with the highest evaporation in both Croatia and Serbia. In its lower course, Bosut flows through a forested area in the region of Spačva. The river is generally known for its abundance of fish.
