The Ider ( Mongolian Идэр гол or Идэрийн гол Ideriin gol ) is the larger of the two source rivers of the Selenga in Mongolia ( Asia ) at 57 m³ / s and the longer one at 452 km and thus hydrologically the main strand of the Yenisei river system. The Ider, which flows mostly eastwards, joins the second source river, Delgermörön, which lasts south-east, to form the Selenge.
course
The Ider arises in the east of the Dsawchan Aimag in the Changai Mountains about 50 km northeast of its highest mountain, the Otgon Tenger Uul . It takes its name from the union of two source streams at an altitude of around 2330 m .
Initially, the Ider flows in the Tarwagatain Mountains Nature Reserve in the foothills of the Changai Mountains in a north-westerly, then in a northerly direction. It then flows mainly to the east-northeast and then turns north on its last kilometers at the confluence of its most important tributary, the Chuluut .
Finally, the Ider joins in the southern part of the Chöwsgöl-Aimag with the Delgermörön coming from the north, which had previously taken in the Bügsiin coming from the west about 1.5 km upstream , at an altitude of 1176 m to the Selenga , the most important tributary of the flowing from the southwest Lake Baikal .
Hydrology, ice drift and navigability
The catchment area of the Ider is around 24,600 km². The river is covered by ice from November to April every year . When the ice and snow melt in spring and summer , floods often occur on the river. The middle and lower reaches of the Ider are navigable .
Flora and fauna
The Ider flows largely through steppe areas. For example, grayling , trout and taimen from the salmon fish family live in the river .
bridges
About 3 km north-west of the Ider inflow Chundschuliin Gol nearby county seat jargalant the Ider from a 1940 built wooden bridge is crossed, the next since 2011 is a new bridge made of reinforced concrete in construction. Another concrete bridge over the Ider is in Galt .
