The Vrana (Bulgarian: Врана) is a 68 km-long river in eastern Bulgaria, a left tributary of the river Golyama Kamchiya, the main stem of the Kamchiya of the Black Sea basin.[1]
The river takes its source at an altitude of 567 m about one kilometer south of the village of Tapchileshtovo. It flows in a wide valley until the village of Prolaz and then enters a deep gorge in direction northeast through the Preslav Mountain of the Balkan Mountains. After emerging from the gorge, its valley widens, making a large convex arc to the north and gradually turns to the southeast. In its lower course the Vrana flows along the southern foothills of the Shumen Plateau. It flows into the Golyama Kamchiya at an altitude of 86 m near the village of Han Krum.[1]
Its drainage basin covers a territory of 938 km2 or 17.5% of the Kamchiya's total.[1] It borders the catchment areas of the rivers Yantra, Rusenski Lom and Provadiya.
The Vrana has predominantly rain–snow feed with high water in March and low water in September–October.[1] The average annual flow is at the village of Kochovo is 2.74 m3/s.[1]
