The Kotschetschum ( Russian Кочечум ), also called Kotschetschuma (Кочечума) or Kotschetschumo (Кочечумо), is about 733 km in length, the largest and at the same time a right or northern tributary of the Lower Tunguska in the western Putorana Mountains , the northern part of the Putorana Mountains North of the Krasnoyarsk Territory , from Siberia and Russia ( Asia ).
course
The Kotschetschum rises in the southeast part of the Putorana Mountains on the southern flank of a 1155 m high mountain at an altitude of about 960 m . It flows through the unpopulated southeastern foothills of the mountains in a predominantly south-southeastern direction and runs through the Sywermaplateau and zones of the forest tundra .
Finally, the Kotschetschum flows as its tributary immediately west of Tura , the former administrative center of the Autonomous Okrug of the Evenki , at 126 m above sea level in the Lower Tunguska, which flows 871 river kilometers below into the Yenisei , which strives towards the Arctic Ocean .
Tributaries, catchment areas and navigability
Among the tributaries of the Kochechum River, whose catchment area km² about 96,400 is large, include Dagaldyn, Agitkan, Jagtali, Upper Anakit, Lower Anakit, Gugdakan, Chungtukun, Upper Maigungda, Lower Maigungda, Embentschime , Gutkengde, Korwuntschana, Sengatschangda, Untuun, Turu , Tembenchi River and condocon. Since the river, with the exception of the Tura at its mouth, flows through unpopulated area, it is not used for inland navigation.
Ice drift and hydrography and hydrology
The Kochetschum is covered by ice from around October to late May or early June . When the region's permafrost thaws and the ice and snow melt, strong floods often occur . Near the mouth, the river is 300 m wide and two to three meters deep; the flow velocity here is 0.8 m / s.
