Geography

The Opir River originates on the eastern slope of Velykyi Yavirnyk Mountain (Ukrainian: Великий Явірник) in the Verkhovinsky range [uk], south of the village of Oporets [uk].[1] It runs between the mountains of the Skole Beskids, mainly to the northeast and north. It flows into the Stryi River between the town of Verkhnie Synovydne and the village of Mezhybrody.

The Opir is 58 kilometres (36 mi) long, with a basin size of 843 km² (325 sq mi).[3] Its average stream gradient is 10.4 m/km (55 ft/mi).[3] The river flows in a V-shaped valley, with a width varying between 150 m (490 ft) and 300 m (980 ft) in the lower reaches.[3] The floodplain is bilateral, sometimes unilateral, with a width ranging from 30 metres (98 ft) to 425 metres (1,394 ft). The shores are steep and occasionally swampy. The stream bed is rocky, with a width of 10 metres (33 ft) to 80 metres (260 ft), and a depth of 0.2 metres (7.9 in) to 1.2 metres (3 ft 11 in). The bottom is usually lined with pebbles of Carpathian sandstones. The river supplies water for settlements and for the irrigation of agricultural lands.

Recently, the river has become popular among tourists who go rafting.[4]

Eight small rivers and 31 streams with a total length of 94.3 kilometres (58.6 mi) and an area of 21.9 hectares (54 acres) flow into the river.
