Ob: the fall of the river and its short description

This major artery Russian born in the Altai region, and then carries the waters to the north, to the Kara Sea.In this article you will find a brief description of the Ob River as planned.In addition, you will also learn how to calculate the slope and fall for any watercourse.

River Ob: Pool Kara Sea

mighty river flows in Western Siberia to the Arctic Ocean, taking a myriad tributaries of different sizes.Once is not called her various nationalities: Kwai, EME Salle Yam, Ob.Fall River, it is worth noting a rather poor performance.The reason is that all of it, including the location of the source, located on the plains.Therefore, differences in elevation along the river is insignificant.

Brief description of the Ob River on the plan can be represented as follows:

  1. length and catchment area.
  2. etymology of the name.
  3. main tributaries of the Ob River.
  4. Istok and the mouth of the watercourse.
  5. Ob: the fall of the river and its bias.
  6. Nutrition and features of the water regime.
  7. organic world of the river.
  8. Navigation and shipping.
  9. Major cities along the river.

Brief description of the river

length of Ob River is 3,650 km.It collects its waters with a huge area of ​​almost 3 million square kilometers (which, by the way, more than the territory of Kazakhstan!).No wonder that almost all the existing names of the waterway can be translated as "large river".But the word "Ob" (modern name) has Iranian roots and translates as "water."The fact that Western Siberia has long inhabited the Iranian-speaking tribes, which probably gave the name of this river.

place where merge Katun and the Biya, considered to be the source of the Ob River.And it carries its waters to the Kara Sea.This river forms a vast delta which ends Ob lip.The main tributaries of the Ob: Irtysh, Vasyugan, Bax, Ket, Chulym.It is interesting to note that even exceeds the Irtysh longest Ob itself.

Power Obi - mainly snow.The period of high water (in different parts of the bed) runs from early April to early May.During the spring opening of the river is often observed large ice jams, which resulted in the spring one can observe a unique situation.The level of water in some areas of the main river temporarily increases, causing some of its tributaries may temporarily change its direction.

Fishing on the river developed since ancient times.Perch, pike-perch, pike, burbot, roach, sturgeon, sturgeon and carp - that's what you can catch in the Ob today.In total more than 50 species of fish living in the river now.Half of them has industrial importance.

history of navigation on the waterway that originates from the middle of the XIX century.In 1844 there was launched the first steamship.By the end of the century on the river, there were already 120 ships, which carried out regular passenger flights.

Today the river are 14 cities.The most important river ports are located in Barnaul, Novosibirsk, Tomsk, Omsk, Tyumen and Khanty-Mansiysk.

Ob: the fall of the river and its bias

As mentioned earlier in this article, the river flows through the plain expanses of Russia.How can you determine the fall of the Ob River?To do this you need to know only two values.First, the absolute height of the mouth (in meters).And secondly, the height of the point source of the river Ob.

Fall River - is nothing more than the difference between the points altitudes its source and mouth.It is clear that this figure depends on the nature and relief dissection particular area.The maximum fall of the river is typical for mountain rivers.

Calculate the slope of any watercourse as it is possible.You need to know the length of the river, and then divide the value of the fall of the river (meters) to its overall length (in kilometers).Thus, we get a value that will actually show how many meters of river "falls" with each kilometer of its length.

calculate these figures for Obi.It is known that the absolute height of the source of the river - 164 meters.Since the Ob, in fact, flows into the ocean, the estuary is at around zero meters.Thus, the total fall of the river is equal to 164 meters.

Now there is nothing easier than to calculate the slope of the Ob River.It is necessary to divide the 164 meters to the length of the river (3650 km).And we get a value of 4.5 cm / km.In other words, for each kilometer of its length track Obi "falls" by 4.5 centimeters.

In conclusion ...

Ob - is the largest river in Siberia, which measured its waters the plains of Siberia to the expanses of the Kara Sea.The length of the river - 3560 kilometers, and its total drop in this very small and is only 164 meters.
