The Kuenga ( Russian Куэнга ) is a 170 km long left tributary of the Shilka in Transbaikalia in the Asian part of Russia .

course

The Kuenga rises at a height of about 1050  m below a pass over the main ridge of the Nertscha-Kuenga Mountains on its south-eastern flank. The low mountain range belonging to the South Siberian Mountains separates the catchment area of ​​the Kuenga from that of the Nertscha, which flows further west (above) into the Shilka, and on this section reaches a height of a good 1200  m . The source is about 35 kilometers as the crow flies northwest of the urban-type Bukachacha settlement .

The Kuenga flows along its entire length in a south-easterly to southerly direction through a relatively narrow and rocky valley, especially on the upper reaches, but also on sections of the lower reaches. This is initially forested, mainly with larches and birches ; to the lower reaches the landscape becomes steppe-like . She finally opens about halfway between the small towns Nertschinsk and Sretensk the village Dunajewo in the Amur -Quellfluss Shilka. Above the mouth, the Kuenga reaches a width of almost 50 meters and a depth of less than a meter. The flow velocity there is 0.6 m / s.

The most important tributaries are the Agita and Aleur from the left and the Olow and Areda from the right.

The name of the river is of Evenk origin, derived either from the word kujan for leg (which is supposed to resemble a mountain near the mouth) or kue for (a kind of) deer and accordingly kuenga about deer place .

Hydrology

The catchment area of the river covers about 7000 km². The average annual runoff at the mouth is 0.402 km³ absolute, corresponding to an average of about 12.7 m³ / s. From late October to late April the river freezes over, occasionally to the bottom.

Use and infrastructure

The Kuenga is not navigable.

From the mouth of the river, near which the Kuenga station of the Trans-Siberian Railway , named after the river, is located at route kilometer 6526 from Moscow in the village of Dunajewo , the route follows the river upwards for 60 kilometers to Chernyshevsk ( Chernyshevsk-Sabaikalski station ), where it is not far crossed by the village and train station Ukurei. This section of the route represents the first part of the Amur Railway , built from 1908 onwards , which branches off the original Transbaikal route to Sretensk, opened in 1901, which crosses the river just under a kilometer above the estuary as a single-track, non- electrified branch route. From Chernyshevsk the route of the Trans-Siberian Railway turns into the valley of the left Kuenga tributary Aleur, while the Kuenga on the left side of the valley is followed by a branch line for a further 50 kilometers, which then branches off into the valley of the larger left tributary Agita and at another 20 kilometers Upstream former coal mining center Bukachacha ends.

The federal highway M58 Amur , part of the transcontinental road link, crosses the river near Chernyshevsk ; a local road branches off there, following the river and railway line to Bukachacha. The R426 regional road from Mogoitui to Sretensk crosses the lower reaches of the river between the village of Verkhnyaya and Nizhnyaya Kuenga .
