For life support of all living organismsfresh water is needed. On our planet, the main resources are natural sources. There are many water systems on the territory of the Russian Federation. Most of the rivers in Russia are fed by soil water and seasonal precipitation.
Distribution of water bodies by Russianregions unevenly. The river network in the central part of our country runs along the plains and plateaus, reaching a maximum in the Siberian taiga and decreasing to the north and south. The lowest density of the river system is observed in the Caspian lowland. Territorial affiliation is an important factor determining what kind of food most rivers of Russia have.
Rivers located on the vast territory of ourcountries, mainly belong to the basin of the Arctic Ocean. The largest waterways of the Ural mountain massif, the Russian Plain and the western part of Siberia are directed to the northern seas. In the east is the Pacific Ocean basin. Rusla pass through mountainous regions, so they have a small extent and a high flow velocity. The rivers of the western part of Russia are in the basin of the Atlantic Ocean, flow into the Baltic Sea, and in the south of the country - into the Black and Azov Seas.
The length of most Russian rivers is less than 10km. Only about two hundred of them have a length of more than 500 km. The hydrological and temperature balance of water bodies depends on the features of the relief, average annual temperature, availability of groundwater, and nutrition. Most of Russia's rivers have mixed food, so the ice regime has a huge impact on the water level.
What type of food does most of the rivers in Russia have?Our country occupies quite extensive territories in temperate and high latitudes. This arrangement is of great importance in the determination of power sources. There are several basic types:
Most rivers in Russia have snow-fed food. The rivers of this category are divided:
Rain water is typical for the western and eastern regions of Russia.
Rivers with a predominance of groundwater are most often found in Kamchatka. Partly eat from groundwater all the water.
The glacial waters feed on mountain rivers predominantly in the North Caucasus region.
Most of the rivers in Russia are powered by threesources: thawed and underground water, rain. A small number of currents are fed from four possible sources. Full-water river systems have a significant national economic significance. They are used for water supply to populated areas, industry, fishing, as transport routes and energy supply.
