The Tembentschi (Russian Тембенчи ) is a 571 km long, right-sided or northwesterly inflow of Kotschetschum in Putoranagebirge, the northwestern part of the Central Siberian Uplands, in the north of Russia's Krasnoyarsk Territory.

Course

The Tembentschi arises in the southern part of the Putoranagebirges about 320 km south east of Norilsk. East of the 1215 m high Dlinnajah, the highest mesa in the Promyslowyberge he entfließt to almost 1000 m altitude a small mountain lake; east of the lake, the there to 1179 m high Ojogongdaberge raise.

First, the flow in a southerly direction through a glaciated valley with steep sides, before he gradually turns to the southeast. This flow direction he keeps by the Sywermaplateau ( large-scale Gebirgssüdausläufer ) extending to its mouth at where he increasingly takes place in wide meanders through a narrow valley.

In the upper reaches it passes through a plurality of elongated lakes, the largest of which lies on 381 m altitude, 45 km long and covers an area of 86.8 km ² engaging Tembentschisee (also Lower Tembentschisee ) is.

The Tembentschi flows about 41 km as the crow north-northwest of the settlement of Tura ( administrative center of the former Autonomous Okrug Evenk ) to approximately 145 m in the Kotschetschum flowing river about 60 miles below it in the Lower Tunguska.

Tributaries and catchment area

Among the many tributaries of the Tembentschi, whose catchment area is about 21,600 km ² in size, include a variety of smaller, often up to several tens of kilometers long rivers, such as the right-side Alik and the largest tributary of the left opens into the upper middle reaches of toads.

Hydrology, hydrography and ice

The mean annual river discharge 89 km above the mouth of 252,73 m³ / s with a minimum monthly average of 4.12 m³ / s in April and 1616.17 m³ / s in June .. The river is from October to May or June of ice covered. When thaw in the summer of permafrost in the region and melt ice and snow, often develop severe flooding that yields about 60 % of the annual runoff in May and June; to September, the flood recedes gradually. In the period November to April accounts for only 5-6 % of the flow.

In estuaries near the Tembentschi is almost 200 m wide, but 1.5 m deep; The flow rate is here 0.8 m / s

Use and infrastructure

Since the Tembentschi flows through virtually uninhabited areas, it is not used for inland navigation. Permanently inhabited villages are missing on the river, and, accordingly, any transport infrastructure.
