An Eco-sustainable World
Nature to be saved



The Ob’ is an arctic river in western Siberia in Russia. This river forms in the northern foothills of the Altai Mountains and, after flowing through the West Siberian Lowland, flows into the Kara Sea, which is part of the Arctic Ocean.
The river is known to Ostyaks as As, Yag, Kolta and Yema, to Samoyeds as Kolta or Kuay, and to Siberian Tatars as Omar or Umar.

Etymology –
The etymology of the name “Ob'” has uncertain origins, but there are several theories about its origin.
One theory suggests that the name “Ob'” may have come from a Turkic or Mongolian word. In the Turkish language, “ob” means “river”, and in the Mongolian language, “oboo” means “river” or “water”. This theory suggests that the name of the Ob’ River may have been adopted from the Turkic or Mongol languages by the indigenous peoples of the region.
Another theory suggests a possible connection with the word “ob'” in the Mansi language, a Finno-Ugric language spoken in western Siberia. In the Mansi language, “ob'” means “water” or “river”, suggesting that the river’s name may have origins in the indigenous languages of the region.
However, it is important to point out that the exact etymology of the name “Ob'” has not yet been definitively established. The complex nature of linguistic evolution and the historical documentation difficulties of the region make it difficult to trace its origin precisely.

Geographic Features –
The Ob’ River flows approximately 3,650 kilometers through a vast and diverse region. It is one of the major rivers of Russia, located in western Siberia. Here are some of its main geographical features:
– Location: The Ob’ River originates in the Altai region, in the eastern part of Western Siberia. It flows northwest through Russian territory for approximately 3,650 kilometers until it empties into the Kara Sea, which is part of the Arctic Ocean.
– Drainage Basin: The Ob’ River Basin is one of the largest in the world, covering an area of approximately 2.99 million square kilometres. The basin includes a large area of West Siberia, including the Altai Mountains, the West Siberian Lowlands, and the North Siberian Marshes.
– Tributaries: The Ob’ River receives numerous tributaries along its course. The main ones are the Irtysh River, which flows into the Ob’ north-east of the city of Khanty-Mansiysk, and the Tom’ River, which joins the Ob’ just upstream from Novosibirsk.
– River regime: The Ob’ is fed mainly by melting snow and by tributary rivers. Its fluvial regime is characterized by a considerable variation of flow during the year. During the summer months, when the snows melt and rain occurs, the river’s flow rate increases significantly.

These are just some of the main geographical features of the Ob’ River. Its natural beauty and ecological importance make it an important asset for Western Siberia and the whole of Russia.

Historical Notes –
The history of the Ob’ River is long and fascinating, with deep roots dating back to antiquity.
The history of human settlement along the Ob’ River can be traced back thousands of years. Early Siberian nomadic tribes settled along the river’s banks to exploit its natural resources, including fish, wildlife and building materials. Fishing has been one of the main activities for the populations that have developed along the river.
Over the centuries, the Ob’ River has been an important waterway for trade and communications. Indigenous peoples of Siberia have used the river as a transportation route to trade goods and merchandise with other communities. In the 13th century, during the Mongol era, the Mongols established a system of trade routes along the Ob River, linking East Asia to Europe.
During the period of Russian exploration in the 16th century, the Ob River became a major route for Russian exploration and eastward expansion. In 1581, Russian explorer Yermak Timofeyevich sailed up the Ob River to conquer Siberian lands for Tsar Ivan the Terrible. This expedition paved the way for the Russian colonization of Western Siberia.
Over the following centuries, the Ob River became increasingly important to the Russian economy. It was used to transport timber, ore, grain and other goods from Siberia to European markets. In the 19th century, with the arrival of the railway, the Ob’ River lost some of its importance as a trade route, but still remained an important inland navigation route.
During the Soviet period, the Ob River was developed for hydroelectric purposes. Several dams were built along the river to generate hydroelectricity. The Novosibirsk Dam, completed in 1957, is one of the largest dams in the world and has helped provide electricity to the Siberian region.
Today, the Ob River is still an important waterway for Western Siberia. Its valley is a region rich in natural resources, including oil, natural gas and coal. The river also supports rich biodiversity, with numerous fish and bird species depending on its waters.
The history of the Ob River is a reflection of the history and development of Western Siberia.
