The Vivi (Russian: Виви) is a river in Krasnoyarsk Krai, Russia. It is a right hand tributary of the Nizhnyaya Tunguska.
The Vivi is 426 kilometres (265 mi) long, and the area of its basin is 26,800 square kilometres (10,300 sq mi).[1]
A damaged An-2 aircraft was discovered in the area of the river Vivi on 28 July 2011.[2]
The Vivi has its source where the southern limit of the Putorana Plateau overlaps with the Syverma Plateau. It begins at the southern end of Lake Vivi and is fast-flowing with many rapids. The Vivi flows roughly southeastwards across the Syverma Plateau in a very remote area where there are very rarely any people.[3]The Vivi joins the right bank of the Nizhnyaya Tunguska near where the latter flows west into the eastern side of the Tunguska Plateau.[4]
There are more than 500 small lakes in the river's basin with a total area of about 268 square kilometres (103 sq mi).[3] The Logancha meteorite crater is also located in the Vivi basin.
