Headwaters Since the construction of the Sava river embankment between Štitar and Županja, what used to be a connection with the Sava river and its outflow channel is now a bay called
Kanal Bosut. There is no significant flow in the channel, so the Bosut River gets its first water from the Berava river, which originates south of
Velika Kopanica, meanders eastwards near
Gundinci and
Babina Greda, and turns north near
Gradište, south of
Cerna. It is believed that Bosut was a branch of the Sava or that there was a Roman canal that led from the Sava to the Berava. The narrow riverbed widens in Cerna where the Bosut receives the water of the Biđ, a long tributary originating in central
Slavonia region, on the southern slopes of the
Dilj mountain. The origin and shape of Bosut, Biđ and their right tributaries are mainly due to the high waters of the Sava and its tributaries
Bosna and
Drina. The outflow named Bosut was created in the last bend of the great meanders of the Sava, and the surges of water caused the flow to stretch all the way to Vinkovci.
Downstream of Cerna Turning north from Cerna, 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 river 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 (where it receives the river
Studva from the right, its major tributary in Serbia) 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 ==
