Geography
The length of the river is 499 km, the catchment area is 25,600 km² [2] . Water consumption 259.97 m² / sec [3] .
The source is from the southern slopes of the Timan Ridge at the Pokyuis ridge.
The largest tributaries: Vorykva , Yolva , Pozheg , Chub - right; Coin , Veslyana are leftists.
In the Vymi basin, Sindor Lake is located, the second largest water mirror in the republic.
It is navigable in the spring to the village of Bozhudor for 30–25 days.
To the city of Emva (located 65 km from the estuary), where a transverse sap is established, a mole alloy of the forest is carried out.
In the upper reaches, Vym is very winding. It has a narrow valley with gentle forested slopes; Bilateral floodplain developed.
In the middle course, it flows in a narrow valley with forested slopes up to 75-80 m high; Small floodplains are found in places. The course is not sinuous. The bottom is sandy and pebble, in some places stony, there are rapids. From the mouth of the Shomukva River to the Elva River, Vym flows in the high root banks.
The width of the river is up to 100 m. The water depth at low water is 1-1.5 m, at rifts - up to 0.2 m. The flow velocity sometimes exceeds 1 m / s. In the middle reaches, the Vym has the features of a semi-mountain river.
In the lower reaches, the Vymi valley expands to 2-3 km; its gentle slopes are mostly forested. The floodplain is mostly narrow, one-sided. The channel is sandy and pebble, up to 200-300 m wide. The water depth is 5-3 m.
Hydrology
Nutrition You mixed, mainly snow. The opening of small rivers and the beginning of spring ice drift in the basin occurs at the end of April - beginning of May and is usually accompanied by an intense rise in the water level, often ice jams. The average duration of ice drift is 6 days. During the flood period, 55–65% of the annual runoff flows along rivers.
Summer-autumn low-water lasts 90-100 days. Often it is interrupted by rain floods, during which the rise in water levels in Vymi can reach 4.5-5.5 m.
The process of river freezing usually occurs in late October - early November and lasts 10-15 days.
Economic Use
Vym is a reserved river, a spawning and spawning river. It contains salmon , nelma , whitefish , sterlet , grayling , bream , ide and other fish species. Fishing of valuable fish species on the Vym and its tributaries is prohibited. Along the shores, a 3 km wide forest protection zone has been established; along the main tributaries it is 1 km.
The missionary activity of Stephen Perm and the beginning of the spread of Christianity in the Komi land are connected with the river.
In ancient times, a river trade route passed through Vymy (“cross-stone” - through the Urals), connecting Northern Europe with North Asia.
