Rivers play one of the most important roles in the life of the planet. For example, for fish this is a house without which their existence is impossible. For animals, this is the source of life, without which they will simply perish. And a person uses water resources in different directions. These are fisheries, shipping, and the construction of hydroelectric power plants for electricity production. In a word, rivers play an important role for all life on planet Earth.
Description of the Lena River
Russia is a country with a huge length, therefore, on its territory there are a large number of rivers. Among them, one of the largest is Lena. Its length is so significant that it occupies the tenth place in the ranking of all rivers on the planet.
It is amazing that such a beautiful river originates in a small swamp, which is located near the cleanest, largest lake Baikal. No wonder the water pool was named after Lena. The nature of the river is so similar to the female! He is constantly volatile. It can be quiet, or maybe aggressive. And it is impossible to predict what it will be around the next corner. Confirmation is evidence that the source of the river is small and narrow, but making its way through many obstacles, eating meltwater and absorbing small streams, the reservoir reaches a depth of up to twenty-five meters and a width of up to twenty meters.
The fall of the Lena River
There is a phenomenon in which the source exceeds the mouth. Usually it occurs on the river in the cold season, when the water supply of the reservoir due to tributaries becomes less. The fall of the Lena River today is 1, 470 meters. The slope is 0.33 / km and is calculated as the ratio of fall to length. Concepts such as the fall and slope of the Lena River are necessary in order to design and build important facilities (hydroelectric power plants). Also, these data are important for water transport.
