Rivers of Bulgaria

The source of the river is in Germany (Black Forest mountains). And then the Danube passes through the territory of ten states. The river flows into the waters of the Black Sea.
Iskar river

The total length of the river is 340 kilometers. The source of the river is the confluence of the two rivers Cherni-Iskar and Beli-Iskar.
Tundzha river
The river flows through the eastern part of Bulgaria and partly through the territory of Turkey. The source of the river is on the southern slopes of the Balkans (Kalofer city). In its upper course, the river passes through the territory of the Kazanlak Valley. Then it turns south, entering the valley of the Maritsa River. And ultimately flows into it near the city of Edirne, becoming a left tributary.
The total length of the river channel is 283 kilometers.
Yantra river

Maritsa river
The Maritsa is one of the largest rivers in the Balkan Peninsula. The length of the channel is 490 kilometers. The source of the river is located near the town of Dolna Banya (eastern part of the Rila Mountains). After that, Maritsa descends to the territory of the Plovdiv Valley, smoothly moving towards Edirne (Greek-Turkish territory). The river flows into the Aegean Sea, before that it forms a swampy delta.
The main tributaries of the Maritsa: Sazliyka; Gyops; Tunja; Ergene; Krichima; Chepelar; Vycha; Arda.
Since the river is fed mainly by rains, in the summer period of the year Maritsa becomes very shallow. Its lower reaches quite often overflow, which is associated with past snowfalls or rains in the upper reaches.
