Lena is a majestic and mighty river, one ofAsia's largest waterways, collects its waters from the vast expanses of Siberia. Its pool is completely within one state - Russia. In this article you will find a brief description of the Lena River, in particular its geographical location, water regime and features of navigation on it.
All rivers are usually described according to a certainalgorithm, which includes several mandatory aspects. It provides for a comprehensive characterization of the watercourse by individual components. Thus, the plan for describing the Lena River in our article will be as follows:
Lena closes the top ten rivers in length in the world(4270 km). This is one of the largest waterways of Russia. This river has one amazing feature: it freezes in one direction (from the mouth to the headwaters), and opens - in the opposite.
Описание реки Лена логично будет начать с explanation of the history of the origin of its name. Oddly enough, but it is not associated with a female name at all. This gidrotoponymy has Evenki roots and initially it sounded like "Elyu-Ene", which means "big river". Over time, this name was transformed in Russian pronunciation to the more familiar sounding word "Lena".
The description of the Lena River, which flows through the expanses of Siberia, will be incomplete without a detailed description of its geographical location. Where does it originate, in what direction does it flow and where does it flow?
Lena and all her numerous tributaries collectits waters from the vast territories of Eastern Siberia. This is approximately 2500 thousand square kilometers. The river originates from a small lake, which, in turn, is almost a neighbor of Baikal. In its upstream Lena carries its waters through the dissected areas of the mountain Cisbaikalia. The average flow of the river has one interesting feature. Here Lena has absolutely asymmetrical shores: the left is low and gentle, and the right is represented by the steep and steep edge of the Patom Highland.
Lena flows into the Laptev Sea. In the lower reaches it is already a giant watercourse, which reaches a width of 10 kilometers! At a distance of 150 kilometers from the mouth of the Lena, a wide delta formed.
On its long way to the sea, the river receives a myriad of tributaries. However, the largest and most significant among them are four: Aldan, Vilyui, Vitim and Olekma.
Features of the hydrological regime is one ofmain aspects, which is included in any physiographic description of the river. Lena eats snow and rainwater. It is characterized by a powerful spring flood, which accounts for about 40% of the total flow, several summer floods and low autumn-winter low water.
The maximum monthly average water consumption recorded in June, they reach 60000 m3/ sec.
A very powerful sight is the spring break-up on Lena, which, as a rule, is accompanied by stormy congestion. The river begins to open in April in the headwaters, and ends - in June, near the mouth.
Economic use of the river is enoughweak, as Lena flows through extremely low-populated areas. Along its bed there are only 6 medium-sized cities. In the largest of them - Yakutsk - only 300 thousand people live. Floating on the river, you can see for hundreds of kilometers nothing but deaf taiga.
The entire length of the Lena, there are only 4 bridges. In populated places, Siberians cross the river using ferries or winter roads.
Surprisingly, Yakutia is one of those regions.Land, where the main transport artery is the river. It is Lena that is the most important highway in this area, through which people, raw materials and goods are transported. The navigation period lasts about 150 days a year. The main ports on the river are as follows:
Lena is one of the largest river systems.Russia, which is completely located in its borders. In addition, it is also the most important transport artery of Siberia, connecting a few of its proud and villages.
A brief description of the Lena River, proposed in this article, gives us a comprehensive and clear picture of its main geographical features, water regime and level of economic development.
