Catchment area of ​​the Dnepr
  • Belarusian part
  • Russian part
  • ukrainian part
  • The Dnepr Basin is the catchment area of the Dnieper River with an area of ​​531,817 km².

    The catchment area of ​​the Dnepr borders in the northeast on the Volga Basin , in the east on the Donets Basin (not to be confused with the industrial region Donets Basin / Donbas), which belongs to the Don Basin , and in the southeast on several small catchment areas whose flowing waters are in the Sea of ​​Azov flow into it. The southern edge of the catchment area borders on other small catchment areas whose rivers flow into the Black Sea. In the south of the catchment area, the main river Dnieper runs into a point west of the city of Kherson and runs over the Dnepr-Bug-Liman - estuary with which the river flows into the Black Sea . In the southwest the catchment area of ​​the Dnepr borders on the Bug Basin (Ukrainian Piwdenny Buh , Russian Juschni Bug) , which laterally adjoins the catchment area of ​​the Dnieper. In the west there is a small border to the Dniester basin and the Vistula basin . In the northwest, the Dnepr catchment area borders the Memel Basin and the Daugava Basin .

    The most striking rivers in the catchment area are the Dnepr with a length of 2201 km and the Desna with a length of 1130 km.

    Geological structure

    Belarus

    “Geologically speaking, the upper Dnieper basin is located in the western part of the old western European plain, which has a two-tier structure. The lower level consists of a crystalline basis of an earlier Archaic-Proterozoic age, which consists of metamorphic and igneous rocks. Above the foundation there is a level made up of different sedimentary rocks.

    In terms of material composition , the bottom at Vitebsk consists of a granite block (in the northern and northeastern part of the basin), a volcanic rock belt at Osnitsa-Mikashevichi (in the central part of the basin in front of Mahiljou ) and at Bragintsy of granite blocks (in the southern and western part of the basin from a granite-gneiss zone).

    In the northern and northeastern parts of the basin and above the cover of the crystalline bedrock is the ' Orsha Vug' extension. To the south it forms the Schlobin Hill and flows into the Pripyat Valley. The basin area near Homel and Dobrusch belongs to the Voronezh Anteklise. The extreme southern part of the basin belongs to the Brahin - Lojeu plateau .

    In Orscha Vug the foundation is up to 1.8 km deep. Riphean, Vendian, and Devonian formations dominate the top of the plain around the Vug. Thin deposits from the Jurassic and Cretaceous periods emerge between the mass of Devonian rocks and the Quaternary sediments.

    The Shlobin Elevation divides the Pripyat River and the Orsha Vug. It is 0.4 to 0.7 km deep. Most of the surface cover consists of upper Proterozoic and Devonian rocks, covered with sediments from the Jurassic and younger sediments.

    In the Pripyat River drains into a depth of 1.5-6 km. For the most part, these are Devonian and coal formations, covered with coal age formations and Permian, Mesozoic and Cenozoic sediments.

    The Voronezh Anteklise comprises 0.5-1 km thick Upper Proterozoic, Devonian, Mesozoic and Cenozoic formations. In the Brahin Loyev Elevation, the foundation lies at a depth of 0.5-2 km and it is covered by Devonian, coal and younger sediments. ”( Prepared by the Republican Center for Radiation Control and Environmental Monitoring (Belarus) and the Ukrainian Center of Environmental and Water Projects of Academy of Technological Sciences (Ukraine) : in "River Basin Management Plan for upper Dnieper" - Chapter: 1.2.

    Ukraine

    “From the town of Lojeu to the Kiev reservoir , the Dnepr flows in a very wide valley, the slopes of which gradually merge with the surrounding terrain. In the northern part of the Kiev reservoir, the width of the valley reaches several tens of kilometers and merges with the surrounding moors and the Pripyat valley. The Dnepr valley narrows further; but its slopes are not noticeable. At the village Lyutish and further down the right slope has a height of 30-50 m, and the river valley only narrows: at the town Vyshhorod and Meschyhirja the right slope comes close to the reservoir. Below the mouth of the Desna River, the Dnepr Valley is very wide.

    Geologically, the upper Dnieper basin in Ukraine is located in the Ukrainian crystalline shield and also in the Dnepr-Donets vug. The connection of these two tectonic structures complicates and changes the geological structure and lithological composition of the basin.

    Regionally (horizontally) the long Dnieper is a contiguous tectonic zone that connects the border between the northwestern Ukrainian crystalline shield slopes and the northwestern side of the Dnieper-Donets-Vug. In other words, the Dnieper divides the basin into two geologically / geomorphologically separate parts: a smaller right and a larger left.

    Edge fractures can be found along the long Dnepr tectonic zone between the southwestern part of the shield and the central Dnepr-Donets block. The divisions are the largest and earliest in terms of deposition and occur in Darnytsia , Kiev , Worsel , Bojarka , Yadlovka-Traktemirovka.

    The division of the Dnepr extends over 150 km to the northwest, it crosses the entire area in its central part and extends far beyond it. In the lower Paleozoic in particular, there were several expansions when the Dnepr-Donets block began to be deposited. Individual breaks occur in the Mesozoic and Cenozoic Era.

    Lithologically (vertically) there are two clearly separated structural levels. The lower tier consists of intricately displaced and metamorphologically altered rocks of the Archean-Proterozoic.

    In the upper Dnepr basin there are neogene red, brown and colored clays and some paleogene deposits (in Poltava , Kharkiv and Kiev) which are covered with a thickness (over 100 m) of aquatic and alluvial deposits. Poor drainage of this area (0-2.3 m) and a widespread occurrence of neogene clays lead to a high water table (0 to 2-3 m).

    Dnepr

    Headwaters of the Dnieper north-east of Smolensk

    Along with the Desna, the Dnepr is one of the two formative rivers of the catchment area.

    Headwaters

    The source of the Dnepr lies northeast of Smolensk, on the southwestern edge of the Valdai Heights near the sources of Daugava and Volga .

    After the source, the river flows through Smolensk , from Mogilev to Kiev from north to south. From Kiev to Dnipro from northwest to southeast. Then from northeast to southwest where it flows into the sea.

    “The Dnepr is the largest river in Belarus and the largest river in Belarus in terms of water content. The main tributaries of the Dnepr are: on the left - the Sosh (648 km long) and on the right - the Drut (266 km long), the Bjaresina (561 km long) and Prypiat (761 km long).

    Almost everywhere in Belarus, from the border with Russia to the Pripyat estuary, the floodplain is bilateral. It has a width of 0.1-1 km near the city of Mahiljou , 3-6 km near Shlobin and 8-10 km in Homel in Polesia . The course of the river meanders with gentle curves and plenty of ridges and shallows. 9 km upstream from Orsha , the river cuts through a ridge of Devonian limestone to form the so-called Kobeljaky rapids near Prydnjaprouje ( Belarusian Прыдняпроўе , Rajon Orsha ). The width of the Dnieper is 60–120 m between the village of Gatkovshchina and the city of Orsha (up to 1.3 km), 0.2–0.6 km between the ridges of Bjaresina and Sosh, 0.8–1.5 km downstream and 3–5 km within the reservoir at the Kiev dam.

    The Dnepr freezes in late November - early December and opens in late March - early April. The maximum ice thickness is 60–80 cm (beginning of March). The spring ice drift lasts 4-9 days. The average water temperature in summer is 19–22 ° C. The highest temperature (28 ° С) was recorded in July 1954.

    The average annual discharge rates are 123 m³ / s near Orsha , 139 m³ / s near Mahiljou and 364 m³ / s near Retschyza . In Orsha the maximum discharge rate is 2000 m³ / s (1931) and the minimum 8 m³ / s (1892). At Retschyza the maximum value is 4970 m³ / s (1958) and the minimum value 36 m³ / s (1921).

    About 25% of the catchment area is occupied by unevenly distributed forest areas. In the catchment areas of the right tributaries to the Dnepr (Bjaresina, Drut) there are extensive forest areas. The left bank area is covered by forests to a much lesser extent. Forests form small patches here, especially in Sosch's short range. Forests are mixed and dominated by pine, fir and oak.

    The share of lakes in the water catchment area is low (less than 1%). Mostly there are small lakes and man-made water bodies, including larger water storage reservoirs: e.g. B. Saslauje - Assipowitschy (on the Swislatsch ), Solihorsk (on the Slutsch ) and Tschyhyryn (on the Drut ).

    Improvement work (drainage) in the water catchment area of ​​the Dnepr affected around 14% of the basin area. 38,500 km of open drainage canals have been in operation since 2006. Another improvement has been achieved in the basins at tributaries, e.g. Drut (11%), Dobysna (28%), Bjaresina (15%), Vedrich (25%), Sosch (11%).

    The river regime was examined at 18 hydrological stations. There are currently 6 hydrological stations in operation: Loyev, Retschyza, Svhlobin, Mahiljou, Solovyovo and Orscha.

    The Dnepr flows into a delta which, united with the Bug , connects to the Black Sea. It is the second largest delta in Ukraine after the Danube Delta. In contrast to the latter, the Dnepr Delta does not have a clearly pronounced triangular shape. It has a square outline. Its average width is 10–12 km, in some places up to 17 km.

    The delta begins about 50 km after the Konka flows into the Dnieper. The Konka is an arm of the Dnieper in the delta. In the south the delta borders on the Oleschky sands . The area of ​​the Dnepr Delta is about 350 km². It is characterized by numerous straits, lakes and still waters, wetlands and some small alluvial islands.

    The floodplains, wetlands and alluvial island of the regions form a unique natural ecosystem known as the Dnieper Marshes, reminiscent of alluvial forests in Central Asia. Precipitation in the Dnepr delta is very low and the water requirement of the delta is almost entirely borne by the water of the river. Esturas are the Konka , Bakaj , Rwatsch , Koschowa and Lytwynka rivers .

    Catchment area of ​​the Pripyat

    Belarusian Polesia

    The Pripyat with a catchment area of 114,300 square kilometers of the larger sub-basins. It empties into the Dnepr, which is dammed into the Kiev reservoir . The catchment area is mostly in the Ukrainian and Belarusian Polesie.

    “As the right tributary of the Dnepr, the Pripyat is the largest tributary in terms of water volume. Its source is in the Ukraine area, it then runs through the Belarus area and returns to the Ukraine area at the end of its course. [..] In the years 1882–2011, the Pripyat discharged 393 m³ / s the "Mozyr" measuring station. (A catchment area of ​​101,000 km² was observed). At the mouth there was a discharge of 450–451 m³ / s (after it had picked up the relatively large Ush). The highest discharge is measured in April, the lowest discharge in September. The highest discharge ever was measured on April 24, 1895 at 5670 m³ / s at the "Mozyr" station. In Ukraine, the Horyn (with its tributary Slutsch ) is the largest tributary of the Pripyat. ”( Prepared by the Republican Center for Radiation Control and Environmental Monitoring (Belarus) and the Ukrainian Center of Environmental and Water Projects of the Academy of Technological Sciences (Ukraine ) : in "River Basin Management Plan for upper Dnieper" - Chapter: 1.3.1.

    The river has a total length of 755 km. Its source is located in the extreme northwest of Ukraine, turns first to the northeast in a major turn, crosses the border with Belarus and finally goes back to the Ukraine after the city of Mazyr in the southeast, shortly before the city of Pripyat . The Pripyat flows from Pinsk to its mouth through a swampy landscape that extends up to 6 km on both sides of the river.

    The Pripyat is part of the Dnepr-Bug Canal , which begins on the Polish border near the city of Brest ; here the muchawez also flows into the bow . Over the canalized Pina , which flows into the Pripyat in the city of Pinsk , the Dnieper-Bug Canal runs to the Dnieper, which leads to the Black Sea.

    Landscape and river bed

    “The width of the Soschstal in its lower course is 230 m and the bed reaches a depth of 5-6 m. The water flowing through can reach a speed of over 1.5 m / s. The stream is mixed with meltwater, which can dominate it. Of the annual runoff, 56% come from the summer-autumn low water period and 54% from the winter low water period. The water level begins to rise in the third 10-day period (10-15 days in the upper course and 20-25 days in the lower course). The average water height at the lowest watercourse is 4-5 m and the highest water height is 6-7.5 m. The summer-autumn low water period (May-June) is often disturbed by floods that exceed the water level by 1-2 m for 25-35 days. Compared to the summer levels, the winter levels are 10-20 cm higher, sometimes up to 2.5 m higher (1939), due to the warm weather in the lower area.

    The river freezes in early December and the ice dissolves in late March - early April, from the mouth to the upper reaches. Along the course of the river in Belarus, the maximum thickness of the ice cover is 62-65 cm (most common in March). The spring ice drift lasts 3-5 days. The average water temperature in June – August is 19–21 ° С and the highest temperature is found in July (28 ° С).

    A special feature of the river regime is its strong variation in discharge. The average annual discharge rates are 105 m³ / s in Slavgorod, 200 m³ / s in Gomel and 219 m³ / s at the river mouth. In Slavgorod the maximum flow rate is 4770 m³ / s (1907) and the minimum 11.1 m³ / s (1900). In Gomel the maximum discharge rate is 6600 m³ / s (1931) and the minimum 16.4 m³ / s (1900). The average long-term discharge rates are between 96.9 m³ / s (1925) and 407 m³ / s (1933).

    The catchment area is covered by about 25% of the forest, especially on the left bank in the middle and lower reaches (characterized by fire and pine forests). There are only a few lakes (less than 1% of the catchment area): individual bodies of water with a water surface of less than 1.0 km². The tributaries include Pronya (11%), Chechera (14%), Besed (10%), Iput (13%) and Uza (27%).

Pine and fir trees predominate, in individual valleys oak and aspen forests or birch forests dominate. The lake share in the catchment area is approx. 1%. The largest lake in the basin is Palik. Man-made water bodies are the Zaslavsk reservoir and the reservoir chain Krinitsa, Drozdy, Chizhovsk and Osipovichi.

    The Beresina freezes in the first half of December and opens at the end of March. The maximum ice thickness is 60 cm. The spring ice drift lasts 4-7 days. A special feature is the flood in late autumn, when the ice contracts. The catchment area was redeveloped. On January 1, 2006, around 16% of the basin area was renovated and an approximately 15,700 km long open drainage network was built. Adjacent basins are also affected by the renovation. The catchment areas of the tributaries Ponya (29%), Plissa (27%), Ola (18%), Sved (30%) and Vedrich (25%) have been rehabilitated to this number. The course of the river is winding in a large arc. The river depth varies between 1.5–3 m and 5–7 m in the lower course. Behind Lake Medzozol, the course along the banks below the village of Brod is heavily overgrown with aquatic plants. The banks are steep and 1–2 m high.

    Catchment area of ​​the Bobr

    The Bobr is a left tributary of the Berezina. It begins 1.5 km northeast of the village of Rafalovo (Tolochin district, Vitebsk oblast) and flows into the Berezina after 357 km near Chernyayevka (Borissov district, Minsk oblast). The main tributaries of the Bobr are Nacha (right side) and Motscha, Jelenka and Plisa (left side). The water catchment area of ​​the Bobr is asymmetrical, complexly shaped, broader in the middle course. The basin is almost evenly covered by forests and has no lakes, moss bogs predominate. The largest moors are located in the catchment area between the Motscha and Nacha rivers. The course of the river is freely meandering and strongly meandering and not branching. The banks are steep, slightly sloping or very steep. The river freezes in mid-December and opens in mid-March.

    Svisloch catchment area

    The Svisloch is a right tributary of the Bersina. It begins 1.5 km southeast of the village of Shapovaly and flows through the districts of Volochin, Minsk, Puchhowichi, Cherven and Osipowichi. The river is originally 257 km long, 297 km after the construction of the Drozdy and Krinitsa reservoirs. The catchment area is 5150 km².

    Its main tributaries are: Vyacha, which flows into the Zaslavsk reservoir, the Wolma and the Bolochanka (on the left), and Titowka, Talka and Sinjaja (on the right).

    The valley is most clearly spread out. In the upper reaches is 400–600 m wide and 1–2 km wide in the middle and lower reaches. The floodplains are double-sided, are 300–500 m wide in the upper reaches and up to 800–1000 m in the lower reaches. From the source of the river to the junction with the Viliya-Minsk canal system, the course is meandering and 3.5 m wide in natural conditions.

    Currently, the course of the river is part of a canal system on which the Zaslavsk reservoir lies downstream and is up to 20-25 m wide. Within the boundaries of the city of Minsk, the Svisloch makes eight curves. The edges are fastened in the city. In the middle and lower reaches the course is curved and deeply cut. The river is 25-30 m wide in this area up to 50 m downstream of the Osipowichi reservoir. The banks are steep and short.

    The natural regime of the river is regulated by reservoirs (Zaslavsk, Krinitsa, Drozdy, Chizhowsk, Osipowichi). The river is filled with water from the Wilija (river). Starting from the Drozdy reservoir, part of the river water is discharged into the Slepyansk water system. It is also planned to drain water into the 50 km long water ring around Minsk.

    Before the construction of the Vilia-Minsk water system, the river froze in mid-December. The flood lasted around 50 days. After the water system was built, the river regime was hardly studied in this regard.

    Artificial waters in the area are water reservoirs and fish ponds. The largest reservoirs are Zaslavsk, Krinitsa, Drozdj, Chischowsk, Vjacha. The course of the river meanders freely. Downstream, near Lake Komsomolskoye, the river is dammed. The bottom is smooth and sandy-muddy. The banks are steep and flat, mostly changing freely and swampy.

    • Tributaries of the Svisloch

    The Wolma is a left tributary of the Svisloch. The river begins with the melioration canal near the village of Korolev Stan in the Minsk district. It flows along the eastern slopes of the Minsk Plateau and the Central Berezina Plain - it flows through the Minsk, Smolewichi, Cherwen and Pushobichi regions. The estuary is 1 km from the village of Svetly Bor in the part of the town of Pushovichi.

    The most important tributaries of the Volma are Wotscha, Gat and Cherwenka (left side) and Sloust (right side). The catchment area is flat and hilly in the upper part, covered by mixed forests (41% of the area). The valley is trapezoidal and 400–600 m wide in the upper reaches and grows up to 3 km wide up to the mouth. Valley slopes are low and moderately steep, the river banks are mostly steep and pronounced 0.4–2 m high. About 20% of the annual runoff of water occurs in spring. Almost the entire floodplain was drained and plowed.

    The river is regulated by four weirs. The upper and middle sections of the watercourse were canalized in 1954, 1969, 1973 and 1984. The river is 3–4 m wide in the upper reaches, 8–10 m in the middle and up to 40 m wide at the river mouth. In 1989 the entire length of the river was deepened and the course was bordered in some parts. The river is used as a water receiver for drainage. Part of the river water is diverted to Svisloch for the ponds and feeds the ponds of the Wolma fish farm (Volma Rybkhoz OJSC) in Ozerny in Cherven Oblast. Carp, crucian carp and pike are bred in the ponds. In the area there is a forest with a hunting area along the shore 400 m south of the village of Ivanichi in Cherven Oblast. The Petrowichi reservoir is also located here in the course of the Wolma. In the vicinity of Smilowichi there are several recreational areas: e.g. B. Zerkalniye Prudy, Krany Bereg, Volma healing places. The nature reserve Juschnowsky and Wolma is located in the upper part of the catchment area of ​​the Wolma.

    Groundwater and hydrogeological characteristics of the catchment area

    The geotectonic structure of the Dnepr basin determines its hydrogeological properties. On the territory of Belarus these are two artesian basins, the Moscow basin (with the Orsha basin) and the Dnieper basin (with the Pripyat basin). The basin edges are attached to anticline parts and slopes of positive tectonic structures in crystalline foundation: the Belarusian and Voronezh anticlis, the Zhlobin and Braginzy-Loyev anticlines, and the Bobruisk outlines.

    The orsha is an artesian basin is the western part of Moscow's mega-basin. In Belarus it occupies the northern and northeastern part of the Dnieper basin. The layer of sedimentary rocks is 1,500–1,700 m thick. The active water exchange zone is from 300-350 m to 200 m thick (in the direction of the Chlobin elevation). It includes water-bearing horizons of Quaternary, Cretaceous, Middle Upper Devonian and Upper Proterozoic deposits.

    The Pripyat is an artesian basin which is located in the southern part of the Dnepr basin in Belarus and is connected to the Pripyat trough. Sedimentary rocks form the thickest layer in the basin - 6,200 m. The active water exchange zone extends to a depth of 200–300 m. It includes aquiferous horizons of Quaternary, Neogene, Paleogene, Cretaceous, Devonian, and Upper Proterozoic deposits.
