The Podkamennaya Tunguska (Russian: Подкаменная Тунгуска, literally Tunguska under the stones; Evenki: Дулгу Катэнӈа, Ket: Ӄо’ль) also known as Middle Tunguska or Stony Tunguska, is a river in Krasnoyarsk Krai, Russia.
History
In 1908, an asteroid impacted near the river and later became known as the Tunguska event.
Hydrology
The river's nutrition is mainly snow (60%); rain and groundwater nutrition account for 16 and 24%, respectively. The flood lasts from the beginning of May to the end of June, in the lower reaches until the beginning of July. From July to October, there is a summer low, interrupted by a rise in the level to 5.5 m during floods, which can be from one to four per year. The average annual water consumption at the mouth is 1587.18 m3/s, during summer floods it reaches 35,000 m3/s. Ice phenomena have been occurring since mid-October, the autumn ice drift of 7-16 days is accompanied by the formation of ice jams.
The ice age is from the end of October to the middle of May. The ice drift lasts 5-7 days in the upper reaches and up to 10 days in the lower reaches, passes violently, with congestion the level rises by 29.7 m. Winter nutrition is weakened due to the location of the river basin in the permafrost zone and reaches the lowest values of 3-15 m3/s, the total winter runoff is 11% of the annual.
In popular culture
The river was the set location in the Call of Duty: Black Ops Escalation DLC map, Call of The Dead.
