The Tschunja ( Russian Чуня ) is a 727 kilometer long right tributary of the Stony Tunguska in Central Siberia ( Russia , Asia ).

course

The Tschunja originates from the Northern Tschunja (Severnaya Tschunja) and the Southern Tschunja (Juschnaja Tschunja) at an altitude of 339  m in the Central Siberian mountainous region . Both have their source in about 430  m in the immediate vicinity of the border with Irkutsk Oblast . Together with the Northern Tschunja, the Tschunja is about 1000 kilometers long; the other source river is only slightly shorter.

The Tschunja flows through the Central Siberian mountains in a predominantly westerly direction in wide arches in a mostly narrow valley with a series of rapids , the most important of which is called Tschunski Samok ( Tschunja Castle ). Finally, the river flows into the Stony Tunguska eight kilometers above (south-east) the Baikit settlement at a height of 143  m as its most important tributary.

The most important tributaries of the Tschunja are Paimbu, Oberer Tschunku (Verkhneje Tschunku) and Unterer Tschunku (Nizhneje Tschunku) from the right and Kimchu, Mutorai and Tychany from the left. In its entire course, the Chunya flows through the territory of the former Evenks Autonomous Okrug of the Krasnoyarsk Territory .

Hydrography

The catchment area of ​​the Tschunja covers 70,500 km². Near the mouth, the river is about 250 meters wide and two meters deep; the flow velocity is 0.4 m / s.

The Tschunja freezes from October to May. During the snowmelt in May and June it leads to high water, just as sporadically depending on precipitation in the other summer months and especially in autumn. The water flow near the mouth is an annual average of 435 m³ / s, in the middle reaches at the mouth of the Mutorai still 146 m³ / s (minimum in March with 11.4 m³ / s; maximum in May with 792 m³ / s) and below the confluence of the Source flows 70 m³ / s (minimum in March with 4.4 m³ / s; maximum in May with 357 m³ / s).

Infrastructure

The Tschunja is navigable for smaller vehicles when the water level is high.

The area through which the Tschunja flows is extremely sparsely populated, so that there is practically no infrastructure. The only places on the river are Strelka (also Strelka-Tschunja; 2007: 202 inhabitants) near the confluence of the Northern and Southern Tschunja and Mutorai (79 inhabitants) at the mouth of the tributary of the same name. A road leads via Strelka from Wanawara on the Stony Tunguska to the northern village of Kislokan; there is no bridge.
