Kochechum River

Location of Kotschetschum ( Кочечум ) in the catchment area of the Lower Tunguska

The Kotschetschum (Russian Кочечум ), also Kotschetschuma ( Кочечума ) or Kotschetschumo ( Кочечумо ) called, is one of about 733 km length of the largest and at the same time a right or northern tributary of the Lower Tunguska in Putoranagebirge, the northwestern part of the Central Siberian Uplands, each in north of the Krasnoyarsk region, Siberia and Russia ( Asia).

Course

The Kotschetschum rises in the southeast part of the Putoranagebirges on the southern flank of a 1155 m high mountain at about 960 m altitude. It flows through the uninhabited East foothills of the mountains in a predominantly south-southeast direction and extends through the Sywermaplateau and zones of the forest-tundra.

Finally, the Kotschetschum flows as an inflow immediately west of Tura, the former administrative center of the Autonomous Okrug Evenk, at 126 m altitude in the Lower Tunguska, which flows 871 kilometers of river below it in the aspiring to the Arctic Ocean Yenisei.

Inflows, basin and navigability

Among the tributaries of the Kotschetschum, whose catchment area is about 96,400 km ², including Dagaldyn, Agitkan, Jagtali, Upper Anakit, Lower Anakit, Gugdakan, Chungtukun, Upper Maigungda, Lower Maigungda, Embentschime, Gutkengde, Korwuntschana, Sengatschangda, Untuun, Turu, Tembentschi and Kondokon. As the river, apart from lying at its mouth Tura, flows through uninhabited areas, it is not used for inland navigation.

Ice conditions and hydrography and hydrology

The Kotschetschum covered approximately from October to late May or early June of ice. When subsequently thaw the permafrost in the region and melt ice and snow, often develop severe flooding. In estuaries near the river reaches a width of 300 m at a depth of two to three meters; the flow rate is in this case 0.8 m / s
