The largest rivers of the European part of Russia are the Volga, Kama, Oka, Don. Rivers of the European part of Russia Which rivers flow in the European south

Russia occupies a vast geographical area, and it is not surprising that numerous rivers spread over its expanses, which played an important historical role in the settlement and development of new lands. Almost all the largest cities of the country are located on the rivers.

In total, there are about 3 million rivers on the territory of the Russian Federation, and all of them are an important component of the life of many people, animals and plants. Rivers provide us with food, water, electricity, places for recreation, and also serve as transportation routes connecting different settlements. It is an irreplaceable source of water for agriculture and industry.

In this article, you can get acquainted with the largest rivers in Russia, get their brief description and see the geographical location on the map of the country.

Rivers of the Russian Federation

Map of the largest rivers of Russia

The territory of the country is divided into European and Asian parts. The dividing line, as a rule, is considered the Ural Mountains and the Caspian Sea. The rivers of the European part flow into the Arctic Ocean, the Baltic Sea, the Black Sea and the Caspian Sea. The rivers of the Asian part flow into the Arctic and Pacific oceans.

The largest rivers in European Russia are the Volga, Don, Kama, Oka and Northern Dvina, while some rivers originate in Russia but flow into other countries, such as the Dnieper and Western Dvina. The following large rivers flow through the Asian expanses of the country: the Ob, Irtysh, Yenisei, Angara, Lena, Yana, Indigirka and Kolyma.

Of the five main drainage basins: the Arctic, Pacific, Baltic, Black Sea and Caspian, the first, located in Siberia and including the northern part of the Russian Plain, is the most extensive. To a greater extent, this basin is filled by the three largest rivers in Russia: the Ob (3650 km), which together with its main tributary, the Irtysh, forms a river system 5410 km long, the Yenisei (3487 km), and the Lena (4400 km). The sum of their catchment areas exceeds 8 million km², and the total water discharge is about 50,000 m³/s.

The major rivers of Siberia provide transport arteries from the interior to the Arctic Sea Route, although they are blocked by ice for a long period each year. The slight slope of the Ob River makes it slowly wind through the vast floodplain. Due to the flow to the north, from the upper reaches to the lower limits of the thaw, extensive floods occur quite often, which leads to the development of huge swamps. Vasyugan swamps on the Ob-Irtysh interfluve cover an area of ​​more than 50,000 km².

The rivers of the rest of Siberia (about 4.7 million km²) flow into the Pacific Ocean. In the north, where the watershed is close to the coast, numerous small, fast-flowing rivulets flow from the mountains, but most of southeastern Siberia is drained by the Amur River. For a larger segment of its length, the Amur forms the border separating Russia and China. The Ussuri, one of the tributaries of the Amur, forms another significant border line between the countries.

Three major drainage basins are located in the European part of Russia south of the Arctic Basin. The Dnieper, only the upper reaches of which are in Russia, as well as the Don and Volga, is the longest European river, originating in the north-west of the Valdai Upland and flowing into the Caspian Sea. Yielding only to the Siberian rivers, the Volga basin covers an area of ​​1,380,000 km². The rivers of the East European Plain have long served as important transport arteries; in fact, the Volga river system provides two-thirds of the movement of the entire Russian inland waterway.

10 largest and longest rivers in Russia

Many mighty rivers flow through the territory of the Russian Federation, but the size of some of them is truly impressive. Below is a list and maps of the largest rivers in the country, both by length and by catchment area.

Lena

The Lena River is one of the longest rivers in the world. It originates near Lake Baikal in southern Russia and flows west, and then, above Yakutsk, smoothly turns north, where it flows into the Laptev Sea (Arctic Ocean basin). Near the mouth, the river forms a huge delta of 32,000 km, which is the largest in the Arctic and the most extensive protected area of ​​wildlife in Russia.

The Lena Delta, which floods each spring, is an important nesting and migratory area for birds and supports a rich fish population. The river is inhabited by 92 planktonic species, 57 benthos species and 38 fish species. Sturgeon, burbot, chum salmon, whitefish, nelma and albula are the most commercially important fish species.

Swans, dippers, geese, ducks, plovers, waders, snipes, phalaropes, terns, skuas, birds of prey, sparrows and gulls are just some of the migratory birds that nest in the Lena's productive wetlands.

Ob

The Ob is the seventh longest river in the world, stretching for a distance of 3650 kilometers in the West Siberian region of the Russian Federation. This river, which is of great economic importance for Russia, arises at the confluence of the Biya and Katun rivers in Altai. It mainly passes through the country, although many of its tributaries originate in China, Mongolia and Kazakhstan. The Ob is connected to its largest tributary by the Irtysh River, at about 69° east longitude. It flows into the Kara Sea of ​​the Arctic Ocean, forming the Gulf of Ob. The river has a huge drainage area, which is about 2.99 million km².

The habitat surrounding the Ob consists of vast expanses of steppe and taiga flora in the upper and middle reaches of the river. Birches, pines, firs and cedars are some of the famous trees growing in these areas. Thickets of willow, wild rose and bird cherry also grow along the watercourse. The river basin abounds in aquatic flora and fauna, including more than 50 species of fish (sturgeon, carp, perch, nelma and peled, etc.) and about 150 species of birds. Minks, wolves, Siberian moles, otters, beavers, stoats and other native mammal species. In the lower reaches of the Ob, the arctic tundra is characterized by snow-covered landscapes for most of the year. Polar bears, arctic foxes, polar owls and arctic hares represent this region.

Volga

The longest river in Europe, the Volga, often considered the national river of Russia, has a large basin covering almost two-thirds of European Russia. The Volga originates in the north-west of the Valdai Upland, and flows south overcoming 3530 km, where it flows into the Caspian Sea. About 200 tributaries join the river along the entire route. Eleven major cities of the country, including Moscow, are based along the Volga basin, whose area is 1.36 million km².

The climate in the river basin varies along its course from north to south. The northern regions are dominated by a temperate climate with cold, snowy winters and warm, humid summers. The southern regions are characterized by cool winters and hot dry summers. The Volga Delta is one of the richest habitats, home to 430 plant species, 127 fish species, 260 bird species and 850 aquatic species.

Yenisei

The mouth of the Yenisei River is located near the city of Kazyl, where it merges with the Small Yenisei River, which originates in Mongolia and flows north, where it drains a vast area of ​​Siberia before emptying into the Kara Sea (Arctic Ocean), having traveled 3,487 km. The Angara River, which flows out of Lake Baikal, is one of the main tributaries of the upper reaches of the Yenisei.

About 55 species of local fish live in the waters of the Yenisei, including Siberian sturgeon, flounder, roach, northern pike, Siberian minnow, tench and sterlet. Most of the river basin is surrounded by, mainly consisting of the following species of coniferous trees: fir, cedar, pine and larch. In some areas of the upper reaches of the Yenisei, there are also steppe pastures. In the north, boreal forests give way to arctic forests. Musk deer, elk, roe deer and Japanese mouse are some of the mammals living in the taiga forests along the river. Also, there are such birds as the Siberian blue robin, Siberian lentil, stone capercaillie and forest snipe. Ducks, geese and swans are found in the lower reaches during the summer.

Lower Tunguska

The Lower Tunguska is a right tributary of the Yenisei, flowing through the Irkutsk region and the Krasnoyarsk region of Russia. Its length is 2989 km, and the basin area is 473 thousand km². The river extends near the watershed between the Yenisei and Lena river basins and flows north and then west across the Central Siberian Plateau.

In the upper reaches, the river forms a wide valley with numerous shallows, but after turning to the west, the valley narrows, and numerous gorges and rapids appear. The vast Tunguska coal basin lies in the river basin.

Amur

The Amur is the tenth longest river in the world, located in East Asia and forms the border between the Far Eastern District of the Russian Federation and Northeast China. The river originates at the confluence of the Shilka and Argun rivers. The Amur flows for 2825 km to the northwestern part of the Pacific Ocean and empties into the Sea of ​​Okhotsk.

The river has many vegetation zones in various parts of its basin, including taiga forests and swamps, Manchurian mixed forests, Amur meadow steppes, forest steppes, steppes and tundra. Wetlands along the Amur Basin are among the most valuable ecosystems that are home to a huge variety of flora and fauna. These are important haunts for millions of migratory birds, including white storks and Japanese cranes. The river basin is home to over 5,000 species of vascular plants, 70 species of mammals, and 400 species of birds. It is home to rare and endangered species such as the Amur tiger and the Amur leopard, the region's most iconic mammal species. A wide variety of fish species inhabit the waters of the Amur: about 100 species in the lower reaches and 60 in the upper. Chum salmon, burbot and whitefish are among the most commercially important northern fish species.

Vilyuy

Vilyuy is a river in Central and Eastern Siberia, flowing mainly through the Republic of Sakha (Yakutia) in eastern Russia. This is the largest tributary of the Lena, 2650 km long and with a basin area of ​​​​about 454 thousand km².

Vilyui originates on the Central Siberian Plateau and first flows east, then south and southeast, and again east to the place where it flows into the Lena (about 300 km northwest of the city of Yakutsk). The river and adjacent reservoirs are rich in commercial fish species.

Kolyma

With a length of more than 2,100 kilometers and a basin area of ​​643,000 km², the Kolyma is the largest river in Eastern Siberia that flows into the Arctic Ocean. The upper reaches of this river system began to develop as early as the Cretaceous, when the main watershed between the Sea of ​​Okhotsk and the Arctic Ocean was formed.

At the beginning of its journey, Kolyma makes its way through narrow gorges with numerous rapids. Gradually, its valley expands, and below the confluence with the Zyryanka River, it flows through the wide marshy Kolyma lowland, and then flows into the East Siberian Sea.

Ural

The Ural is a large river flowing in Russia and Kazakhstan, 2428 km long (1550 km on the territory of the Russian Federation), and with a basin area of ​​​​about 231 thousand km². The river originates in the Ural Mountains on the slopes of the Round Sopka and flows in a southerly direction. In the city of Orsk, it turns sharply to the west through the southern outskirts of the Urals, past Orenburg, and again turns south, heading towards the Caspian Sea. Its flow has a large spring maximum, and freeze-up lasts from late November to April. Navigation on the river is carried out to the city of Oral in Kazakhstan. The dam and hydroelectric power station were built on the Iriklinskoye reservoir, south of the city of Magnitogorsk.

Wetlands in the Ural Delta are especially important for migratory birds as a major haunt along the Asian Flyway. The river is also important for many Caspian Sea fish species that visit its deltas and migrate upstream to spawn. In the lower reaches of the river, there are 47 species from 13 families. The cyprinid family accounts for 40% of the species diversity of fish, sturgeon and herring - 11%, perch - 9% and salmon - 4.4%. The main commercial species are sturgeon, roach, bream, pike perch, carp, asp and catfish. Rare species include Caspian salmon, sterlet, nelma and kutum. About 48 species of animals live in the Ural delta and nearby areas, of which 21 species belong to the order of rodents.

Don

The Don is one of the largest rivers in the Russian Federation and the 5th longest river in Europe. Its basin is located between the Dnieper-Donets depression in the west, the Volga basin in the east, and the basin of the Oka River (a tributary of the Volga) in the north.

The Don originates in the city of Novomoskovsk 60 km southeast of Tula (120 km south of Moscow), and flows for a distance of about 1870 km to the Sea of ​​Azov. From its source, the river heads southeast to Voronezh and then southwest to its mouth. The main tributary of the Don is the Seversky Donets.

Table of the largest rivers of the Russian Federation

The largest river in Europe located in Russia - this is a river Volga(3531 km) and this is not surprising, because the territory of the European part of Russia is 40% of the territory of all of Europe.

Many sources claim that the longest river in Western Europe is Danube(2860 km), however, it is worth noting that the Danube flows through the territories of such Eastern European countries as Slovakia, Hungary, Bulgaria, Romania, Moldova and Ukraine.

The Danube is divided into 3 parts:

• Upper (992 km) - from the source to the village of Gönyü;
• Medium (860 km) - from Gonyu to the city of Drobeta-Turnu Severin;
• Nizhny (931 km) - from the city of Drobeta-Turnu Severin to the confluence with the Black Sea.

At the same time, even part of the upper Danube already flows through the territory of Slovakia, which means that in Western Europe the length of the Danube is less than 992 km.

Therefore, if we consider the west and east of the continent separately, then the largest river in Western Europe- This Rhine 1233 km long, which flows through the territories of such Western European countries as Germany, Austria, Switzerland, France, the Netherlands and Liechtenstein.

Well, the Danube can be considered as the longest river in the European Union.

RIVER REST

Volga - the largest river in Europe, 3888 km long with a basin area of ​​\u200b\u200b1360 thousand km 2. It originates in the Valdai Upland, flows into the Caspian Sea, forming a delta with an area of ​​19 thousand km 2. It has about 200 tributaries, the largest being Kama and Oka. The flow is strongly regulated by a cascade of hydroelectric power stations with reservoirs. The largest hydroelectric power stations are Volzhskaya (Kuibyshevskaya), Volzhskaya (Volgogradskaya), Cheboksarskaya. The Volga is connected to the Baltic Sea by the Volga-Baltic Waterway, to the White Sea by the North Dvina Water System and the White Sea-Baltic Canal, to the Azov and Black Seas by the Volga-Don Shipping Canal, and to the Moscow River by the Moscow Canal. The Volga-Kama, Zhigulevsky and Astrakhan nature reserves, the natural national park Samarskaya Luka are located in the Volga basin.

Kama - the fifth longest river in Europe (2030 km): only the Volga, Danube, Ural and Dnieper are longer than it, Kama is one of the most important river routes, it has more than 200 large tributaries, such as Vishera, Chusovaya, Belaya, Vyatka, etc. The Kama River is regulated for a considerable length by the dams of the Kamskaya, Botkinskaya and Nizhnekamskaya hydroelectric power stations, above which reservoirs have been created. At the confluence of the Kama and the Volga, there is the Volzh-1-sko-Kama Reserve.

The nature of the Kama basin It is diverse and includes the slopes of the Ural Range, ancient plateaus, and low-lying plains. In the upper reaches there are coniferous forests, in the lower reaches there are oak groves and lindens.

Oka - the second largest tributary of the Volga, has a length of 1478 km. It originates on the Central Russian Upland, 4 km from the village. Maloarkhangelsk. It flows into the Volga near Nizhny Novgorod. According to hydrological data and the nature of the route, it is divided into upper, middle and lower sections. Upper Oka - from the city of Aleksin to the village. Shchurovo. Average - from s. Shchurovo (the mouth of the Moscow River) to the mouth of the river. Moksha. Here it differs sharply from the upper section - the slopes decrease, the river becomes more abundant. For 100 km (R. Shchurovo - Kuzminsk) there is a sluice section. The Lower Oka (from the mouth of the Moksha River to Nizhny Novgorod) is characterized by frequent narrowing and widening of the channel from 1 to 2 km. The right bank (from Pavlov to Gorky) is high, the left bank (from Murom to Nizhny Novgorod) is low. On the banks of the Oka, on the one hand, there are cliffs, on the other, flood meadows. Closer to the confluence of the Volga, the Oka becomes full of water, coniferous forests and copses appear on the banks.

The main tributaries of the Oka: Ugra, Moscow River, Klyazma, Moksha. On the left bank in the middle reaches is the Prioksko-Terrasny Reserve. The Oka is navigable from the city of Chekalin, regular shipping is from Serpukhov.

Don begins on the Central Russian Upland. The length of the Don is about 1970 km, the area of ​​the basin exceeds 440 thousand km2. It flows into the Taganrog Bay of the Sea of ​​Azov, forming a delta with an area of ​​340 km2. Small slopes in the lower reaches provide a very slow current. Main tributaries: Khoper, Medveditsa, Sal, Seversky Donets. On the Don are the Tsimlyanskaya hydroelectric power station and a reservoir, the Nikolaevsky, Konstantinovsky and Kochetkovsky hydroelectric facilities. Navigation from the mouth of the river. Sosny (1604 km), regular navigation - from the city of Liski. In the Don basin - Galichya Gora nature reserve. The largest cities: Liski, Kalach-on-Don, Rostov-on-Don, Azov, Volgodonsk.

The river network is most developed in the northern part of the region, in the zone of excessive moisture (forest zone). As we move south, the surface and underground runoff decreases more and more, the amount of precipitation decreases, the relative evaporation losses increase, underground waters lie deeper, etc. In accordance with this, the river network becomes less and less, and in arid steppes and especially already vast drainless spaces appear in the semi-desert, that is, areas devoid of permanent rivers.

The hydrographic network in such places is represented by dry channels that operate for a short time during the period of snowmelt or heavy rains. Large rivers - the Volga and the Dnieper - flowing through the steppe spaces, receive only relatively small tributaries and little increase their water content. In the semi-desert zone, they even lose some of their water to evaporation and filtration (the Volga below Volgograd, the Urals).

In the steppe and forest-steppe zones, especially in areas where loess soils are distributed, a ravine-gully network has been widely developed, representing a dense network of temporary watercourses that operate only during the period of snowmelt or heavy rainfall. In some places, the rapidly growing network of ravines causes great damage to agriculture, destroying fertile black earth soils.

Most of the watercourses of the region are among the typical lowland rivers. They usually have well-developed valleys with wide, often swampy floodplains, abundant lakes and old rivers. Their current velocities and slopes are also low, not exceeding 0.1-0.3°/oo. Sharp fractures of the longitudinal profile are rare and confined to places of shallow occurrence of bedrock, cut in some places by rivers. There are a large number of unstable sandy rifts in the riverbeds.

On large rivers (Volga, Don, Dnieper, etc.), the asymmetry of the slopes of the valleys is clearly expressed: the right bank is usually high and steep, the left is gentle and low. The explanation for this is found in the deviation of the flow of rivers to the right under the influence of the rotation of the Earth (the Coriolis force).

The main river of the Black Sea-Caspian slope is the Volga, followed by the Dnieper and Don. Among the major rivers is also in the southeast - the Urals.

The Volga is one of the largest rivers: Europe. Among the rivers of Russia, it occupies the sixth place, yielding in terms of catchment area only to the Siberian giant rivers - the Ob, Yenisei, Lena, Amur and Irtysh. It originates on the Valdai Hills, where the source is taken as a key, fastened with a wooden frame near the village of Volgine. The source mark is 225 m above sea level. The Volga flows into the Caspian Sea. The length of the river is 3690 km, the basin area is 1380000 km2.

In terms of its catchment area (220,000 km 2) and length (2,530 km), the Urals is one of the largest rivers in the European part of Russia. It originates in the Southern Urals near the source of the river. White (left tributary of the Kama) and initially flows straight south. Near the city of Orsk, it turns sharply to the west, and, having passed in a latitudinal direction of about 850 km, in the region of the city of Uralsk it again turns south almost at a right angle and maintains this direction until it flows into the Caspian Sea. According to these three main directions, the Urals are usually divided into three sections: the upper one - from the source to the city of Orsk, the middle one - between the cities of Orsk and Uralsk, and the lower one - from the city of Uralsk to the mouth.

Economic importance and use of the rivers of the southeastern part of the region

Of the rivers in the southeastern part of the region, the Urals are of the greatest importance, the waters of which in the upper reaches are widely used for water supply to cities and enterprises of the industrial Urals. A number of reservoirs have been built here, supplying water to Magnitogorsk, the Orsk-Khalilovsky plant and other cities and industrial enterprises. In the lower reaches, the Ural is used for navigation.

In terms of the catchment area of ​​422,000 km 2, the Don ranks fourth among the rivers of the European part of Russia, second only to the Volga, Dnieper and Kama. The length of the river is 1970 km. The source of the Don is located in the northern part of the Central Russian Upland, at an altitude of about 180 m above sea level. For its beginning, the place of exit from the lake was previously taken. Ivan. In reality, there is usually no runoff from Ivan Lake to the Don. For the origins of the Don, it is customary to consider the keys located somewhat south of the lake. Ivan.

The Dnieper is the third largest river in the European part of the country after the Volga and Kama. It originates in the Smolensk region from a moss swamp (near the village of Kletsovo), at an altitude of about 220 m above sea level. Flowing through the territory of Belarus and Ukraine, the Dnieper collects water from a vast basin with an area of ​​503,000 km 2. The length of the river from its source to its confluence with the Dnieper-Bug Estuary of the Black Sea is 2285 km.

The Dnieper is one of the lowland rivers. The river valley is well developed and has a wide floodplain, where the channel is divided into numerous branches. By the nature of the valley and channel, as well as by a number of other features, the Dnieper is usually divided into three sections: the upper one - from the source to the city of Kyiv, the middle one - from the city of Kyiv to the city of Zaporozhye and the lower one - from the city of Zaporozhye to the mouth.

The Upper Dnieper covers most of the basin (approximately 65%), located in the forest zone and characterized by the most developed river network. Above the city of Kyiv, its large tributaries flow into the Dnieper: the Berezina, Sozh, Pripyat and Desna. In this part of the basin, the main flow of the river is formed, more than 80% of the total flow already passes in the alignment of Kyiv. From the source and almost to the city of Orsha, the Dnieper flows along the border of the penultimate glaciation. Here, in some places, when crossing the moraine ridges, the river valley narrows and the river forms rapids, full of boulders.

5 km above the city of Orsha, the Dnieper crosses a ridge of gray sandstone and forms the famous Kobelyak rapids, which are a significant obstacle to navigation in low water.

Below the city of Orsha, up to the city of Kyiv, the Dnieper flows along the bottom of a wide valley, reaching in places a width of 10-14 km. Among the vast, sometimes swampy floodplain, the Dnieper channel forms numerous bends.

A characteristic feature of the middle Dnieper is a pronounced asymmetric valley, the right root bank of which is high and steep, and the left bank is gentle and low. Here the river, as it were, presses its right bank against the Volyn-Podolsk upland and goes around it. On the left, an ancient terrace adjoins the Dnieper, which looks like a wide, gently sloping plain. The main tributaries of the middle Dnieper are Sula, Psel, Vorskla. In the lower part of this section, from the city of Dnepropetrovsk to the city of Zaporozhye, the Dnieper crosses the Azov-Podolsk crystalline massif for 90 km in its lowest part. Here were the famous Dnieper rapids with a total drop of more than 32 m, which for many centuries was an obstacle to navigation.

During the years of Stalin's five-year plans, the most powerful hydroelectric power station in Europe, the Dneproges, was built in the region of the Dnieper rapids; its 37 m high dam completely blocked the rapids, forming a reservoir in their place, named after V. I. Lenin. So, in those days, the problem of improving the navigation conditions of the Dnieper was radically solved.

Below the Dnieper hydroelectric power station, the Dnieper enters the Black Sea lowland. The terrain along both banks of the river takes on a steppe, flat character. The slope of the river becomes insignificant (0.09-0.05°/oo); the total drop from Zaporozhye to the mouth is only 14 m. The riverbed is divided into many branches, forming flat sandy islands overgrown with reeds. These are the so-called Dnieper floodplains, which are up to 20 km wide and limited on the left side of the river. Konka, which makes up the boundary of the left floodplain of the Dnieper.

Below the city of Kherson, the Dnieper forms a delta, flowing into the Dnieper Estuary with many branches. Having a large catchment area, the Dnieper is not characterized by high water content. Its average annual water flow at its mouth is 1700 m 3 /sec, which corresponds to a runoff modulus of 3.1 l/sec km 2. In terms of its water content, the Dnieper ranks sixth among the rivers of the European part of the former Soviet Union, yielding not only to the Volga and Kama, but also to the Pechora, Northern Dvina and Neva. With a catchment area slightly inferior to the Kama, the average annual water flow of the Dnieper is about 2 times less than the flow of the latter.

As on other rivers of the European part, the Dnieper experiences a high spring flood, which is formed due to the melting of snow accumulated over the winter in its basin. More than 50% of the total annual flow passes in spring. The peak of the flood in the upper reaches is in mid-April, and in the lower reaches - in early May. After the passage of the flood, the level in the river drops sharply and during June, July and August there is a low low water. The lowest level is observed in July.

The amplitude of level fluctuations is quite significant, especially in the upper reaches. In the Smolensk region, for example, it reaches 12 m. Below is information on the length, catchment areas, and water discharges of the main tributaries of the Dnieper (Table 1).

River use. The Dnieper has long played an important role in the economic life of our country. Back in the 10th-12th centuries, the famous route "from the Varangians to the Greeks" passed along it.

Navigation begins on the section of the upper Dnieper near the city of Dorogobuzh and is carried out along the rest of the river. The importance of the Dnieper as a waterway increased especially after the construction of the Dnieper hydroelectric power station, when the Dnieper basin received direct communication with the sea. With the help of connecting water systems, the Dnieper is connected with adjacent basins: the Berezinskaya system connects it with the Western Dvina basin, the Dnieper-Neman Canal - with the Neman basin, the Dnieper-Bug Canal - with the Western Bug basin.

It should be noted that these Black Sea-Baltic water systems, built at the beginning of the last century, are unsuitable for modern navigation. The rivers included in the systems (Neman and Zapadnaya Dvina) are not regulated and, differing in rapids, are inaccessible for through navigation. During the Patriotic War, the structures of the Dnieper-Bug Canal were destroyed, but restored after the war.
