Kotuy River

Last updated April 15, 2019

The Kotuy River (Russian : Котуй) is a river in Krasnoyarsk Krai, Russia. It is one of the two rivers that form the Khatanga River; the other one being the Kheta River.

Russian is an East Slavic language, which is official in the Russian Federation, Belarus, Kazakhstan and Kyrgyzstan, as well as being widely used throughout Eastern Europe, the Baltic states, the Caucasus and Central Asia. It was the de facto language of the Soviet Union until its dissolution on 25 December 1991. Although nearly three decades have passed since the breakup of the Soviet Union, Russian is used in official capacity or in public life in all the post-Soviet nation-states, as well as in Israel and Mongolia.

A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as stream, creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague.

Krasnoyarsk Krai is a federal subject of Russia, with its administrative center in the city of Krasnoyarsk—the third-largest city in Siberia. Comprising half of the Siberian Federal District, Krasnoyarsk Krai is the largest krai in the Russian Federation, the second largest federal subject and the third largest subnational governing body by area in the world, after Sakha and the Australian state of Western Australia. The krai covers an area of 2,339,700 square kilometers (903,400 sq mi), which is nearly one quarter the size of the entire country of Canada, constituting roughly 13% of the Russian Federation's total area and containing a population of 2,828,187, or just under 2% of its population, per the 2010 Census.

The Kotuy River is 1,409 kilometres (876 mi) long, and the area of its basin is 176,000 square kilometres (68,000 sq mi). It freezes up in late September or early October and breaks up in late May or early June. Its main tributaries are the Moyero, the Kotuykan, the Eriyechka, the Changada, and the Tukalan.

Area Quantity that expresses the extent of a two-dimensional surface or shape, or planar lamina, in the plane

Area is the quantity that expresses the extent of a two-dimensional figure or shape, or planar lamina, in the plane. Surface area is its analog on the two-dimensional surface of a three-dimensional object. Area can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape, or the amount of paint necessary to cover the surface with a single coat. It is the two-dimensional analog of the length of a curve or the volume of a solid.

A drainage basin is any area of land where precipitation collects and drains off into a common outlet, such as into a river, bay, or other body of water. The drainage basin includes all the surface water from rain runoff, snowmelt, and nearby streams that run downslope towards the shared outlet, as well as the groundwater underneath the earth's surface. Drainage basins connect into other drainage basins at lower elevations in a hierarchical pattern, with smaller sub-drainage basins, which in turn drain into another common outlet.

A tributary or affluent is a stream or river that flows into a larger stream or main stem river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean.

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
