The mighty river Amur

Geographical position

The Amur River is one of the largest water arteries that flow through the territory of Siberia. By its parameters, it ranks fourth after the Ob, Yenisei and Lena. This is the only Siberian river that flows into the Pacific Ocean. All others carry their waters in the Arctic. It is important to note that at a considerable distance along the fairway of the river passes the border between the Russian Federation and the People’s Republic of China. A significant part of the catchment area is located on the territory of the neighboring state. This fact affects the state of the ecological system of the river, as will be discussed below.

Length and tributaries

The Amur River is formed by the confluence of two rivers - Shilka and Argun. Its length from the point of confluence to the confluence of the Tatar Strait is almost three thousand kilometers. Some experts suggest measuring its length in total with the length of the Shilka River. Then the length will be already 4500 km. Throughout its course, the Amur River absorbs the waters of numerous tributaries.Among the largest appear Bureya, Zeya, Sungari and Ussuri. In the 19th century, being in the military service, the famous theorist of anarchism Peter Kropotkin took part in an expedition to survey the bed of the Sungari river.

Environmental problems of the Amur RiverFeatures of the water regime

In its upper section, the Amur River has a mountainous nature of flow. This section - from the confluence of Argun and Shilka to the city of Blagoveshchensk - stretches nearly 900 km. In the middle course - between Blagoveshchensk and Khabarovsk - the riverbed runs through flat terrain. The lower section, from Khabarovsk to the mouth, is located in the Lower Amur Lowland. There are many large lakes that connect with the river channels. The main sources of power for the Amur River are summer rain showers. Monsoons bring large masses of rain clouds from the Pacific Ocean. Almost 70% of runoff is formed due to precipitation in the form of rain.

Power sources of the Amur RiverFlora and fauna

Sharp and significant in size fluctuations in water level affect the aquatic vegetation and the composition of animals that live here. The Amur River attracts many species of fish that belong to different classes. Salmon is an arctic resident.A snakehead and killer whale belong to the tropical species. Due to its unique position, the river has long attracted hunters, fishermen and other miners. Till now it is not possible to cope with poachers who shoot the Amur tiger and catch the Kaluga prohibited for fishing. Kaluga is a valuable fish whose weight can reach a ton.

Amur River photoEcological situation

Intensive human activity — industrial production and the cultivation of crops — adversely affects the state of the river. The environmental problems of the Amur River are aggravated by the fact that two states, Russia and China, are responsible for its condition. With this dualism it is very convenient to shift the blame for the discharge of untreated industrial waste to the opposite side. The large cities that are located on its banks also have a negative impact on the ecological state of the river. Currently, environmental issues are receiving great attention. From budgets of different levels, significant resources are allocated to restore proper order.
