Lena - majestic and mighty river, one of the largest waterways of Asia, gathers its water from the vast expanses of Siberia.Its swimming pool is entirely within a single state - Russia.In this article you will find a brief description of the Lena River, in particular, its geographical position and the characteristics of the water regime of navigation on it.
plan describing the Lena River
All the rivers are usually described by a certain algorithm that includes some mandatory aspects.It provides a comprehensive description of the individual components of the watercourse.So, plan to describe the Lena River in this article will be the following:
- name of the river, as well as the history of its origin.
- Geography River (geographic location, source and estuary area of the river basin, the structure of the river system, listing the major tributaries, etc.).
- hydrology of the river (the average monthly consumption of water, especially the water regime, freezing and opening of a watercourse, etc.).
- specifics of the economic use of the river man (population banks, shipping, ports and major bridges on the river, water protection and the banks, etc.).
River Lena: a brief description of
Lena River is the tenth longest in the world (4270 km).This is one of the major waterways of Russia.In this river, there is one surprising feature: it freezes in one direction (from the mouth to the headwaters), as revealed - in reverse.
Description Lena River would be logical to start by explaining the history of the origin of its name.Oddly enough, but it is not associated with a woman's name.This has gidrotoponim Evenki roots and initially it sounded like "Yeh-lii-UNE", which means "great river."Over time, this name was transformed into the Russian pronunciation of a more familiar-sounding word "Lena".
Geography River
Description Lena - the river flowing across the expanses of Siberia, is incomplete without a detailed characterization of its geographical position.Where it originates, in which direction is flowing and where flows?
Lena and all its numerous tributaries collect their water from the vast territories of Eastern Siberia.It is approximately 2,500 square kilometers.The river originates from a small lake, which, in turn, is practically a neighbor of Lake Baikal.In its upper reaches of the Lena carries its waters through the territory of the dismembered mountain Predbajkalja.The average flow of the river is different interesting feature.Here Lena has absolutely asymmetric coast: left - low and flat, and the right is represented by steep and precipitous edge Patom Highlands.
Lena flows into the Laptev Sea.In the lower reaches it is a giant waterway that reaches a width of 10 kilometers!At a distance of 150 kilometers from the mouth of the Lena River delta formed wide.
on his long way to the sea the river takes in countless tributaries.However, the largest and most significant among them are four: this Aldan, Viluy, Vitim and Olekma.
river hydrology
Features hydrological regime - is one of the main aspects that is included in any physical and geographical description of the river.Lena eats snow and rain waters.It is characterized by a powerful spring flood, which accounts for about 40% of the total flow, several summer floods and the low autumn and winter low water.
maximum monthly water consumption figures recorded in June, they reach 60,000 m3 / s.
very powerful sight - Spring break on the Lena, which is usually accompanied by a thunderous jams.The river starts to be opened in April in the upper reaches and ends - in June at the mouth.
The population of the river banks and shipping
economic use of the river is quite weak, as Lena flows through extremely nizkozaselennoy areas.Along the channel it is located only 6 medium-sized cities.The largest of them - Yakutsk - home to only 300,000 people.Floating on the river, hundreds of kilometers can not see anything but the taiga.
the entire length of the Lena River, there is only 4 bridges.In populated areas Siberians cross the river via the ferry or winter roads.
Surprisingly, Yakutia - is one of those regions of the world, where the main traffic artery of the river stands.That Lena is the most important thoroughfare of the area, in which you are carrying passengers, raw materials and freight.The navigation period lasts about 150 days a year.The main port on the river are the following:
- Sangar.
- Yakutsk.
- Pokrovsky.
- Olekminsk.
- Lensk.
- Kirensk.
- sturgeons.
In conclusion ...
Lena - this is one of the largest river systems in Russia, which is fully located in its borders.In addition, it is also important highways of Siberia, joining a few of her proud and villages.
Brief description of the Lena River, proposed in this paper gives us a comprehensive and clear view of its main geographical features, water regime and level of economic development.
