The Irkut ( Russian Ирку́т ; Mongolian and Buryat Эрхүү гол ) is an approximately 488 km long, left-hand or western tributary of the Angara in Siberia , Russia ( Asia ).
course
The river arises in the southwest of the Republic of Buryatia in the eastern part of the Eastern Sayan , a high mountain range of the South Siberian Mountains . He entfließt the on 1,952 m located height Iltschirsee , among other things, from the from the mountain Iltschir ( 2,352 m coming) and about 10 km long Iltschir fed.
In Eastern Sayan, the Irkut first flows a little to the west and then a little to the south and southeast. It passes the massif of the Munku Sardyk ( 3492 m ) located immediately southwest of the river , after which it turns to the east and flows into the Tunka National Park . From now on it runs winding through the large Tunka basin , which, like the park, lies in the region of the river Kyren . After the confluence of its largest tributary, Sun-Muren , the Irkut leaves the park about 40 km west of Lake Baikal , through which it does not flow, at an altitude of about 660 m , which corresponds to the lowest parking spot.
Shortly thereafter, he entfließt and the lowlands of Tungabeckens to the same time to leave the Republic of Buryatia and the Irkutsk Oblast to achieve. After flowing through two elongated river loops or change of direction, which are located west of Lake Baikal, the Irkut leaves the eastern foothills of the Eastern Sayan in order to then run northeastward, passing the town of Schelechow .
After crossing under the Trans-Siberian Railway , the Irkut flows into the Angara tributary of the Yenisei River, coming from the south or from this reservoir, about ten kilometers below the Irkutsk reservoir dam in the city of Irkutsk at an altitude of about 405 m .
Hydrology and catchment area
The Irkut, whose catchment area covers around 15,780 km², usually freezes over from late October or mid-November to late April or early May. Its discharge , which averages 142 m³ / s, was around 11.5 m³ / s in January 1987 and around 296 m³ / s in June 1987, i.e. about 1/100 to 1/10 of the Angara below the reservoir (2070 m³ / s in January and 1960 m³ / s in June).
