MAIN RIVER BASINS. The overwhelming majority of rivers in Ukraine (94 %) belong to the Black sea and the Azov sea basins. Only the rivers of the western part of the country are related to the Baltic sea basin. Some small rivers in the south of the country have no streamflow into the World Ocean. Such distribution of river run-off is caused by the general structure of the surface of Ukraine.

THE RIVERS OF THE BLACK SEA BASIN. At all times all over the world rivers played the important role in life and activity of human beings. In some places they have so strongly become usual and inherent to economic activities and culture of people that they became their national symbols.


Thus it is impossible to imagine Ukraine without the Dnieper-Slavutych. For us it is not only the powerful waterway, picturesque beauty, but also the reflection of the soul of our nation, its history. On the banks of the Dnieper the kernel of the Ukrainian state – golden-domed Kyyiv was formed, the first Ukrainian democracy - the Zaporizhzhya Cossacks was born, fr om its steep slopes the national genius Taras Shevchenko admires the native spaces.

The Dnieper  flows along the middle part of Ukraine fr om the north to the south. It collects waters almost fr om half of the country’s area, fr om its northern, western and eastern territories. The river begins with a small bog on the Valdai Hills, in Russia, at height of 220 m above sea level. Further it flows over the territory of Belarus and enters into Ukraine as the big flat river with a wide valley. It has a twisting channel with shallows, sleeves and islets. Depth of the Dnieper amounts to 3-12 m, width is 700-1 500 m. In its flood-lands there are many former river-bed lakes, boggy sites. The right bank of the river is high and mountainous, whereas the left one is low and flat. In areas where the Dnieper crosses the Ukrainian crystal board (between Dnipropetrovsk and Zaporizhzhya) once there were rapids that completely partitioned off the river. Now all of them are flooded by the waters of the Dniprovskyy reservoir. A number of reservoirs formed on the Dnieper did not only flood the rapids but also considerably changed the banks of the river and straightened its channel. On the Dnieper there are many islands (the Hortytsya within Zaporizhzhya, the Trukhanov within Kyyiv). With several creeks the Dnieper flows into the Dniprovsky estuary, and fr om it with one wide mouth — into the Black sea.

The Dnieper has over 1 150 of small, middle-size and large feeders. The largest of them are the Prypyat (right feeder) and the Desna (left feeder). They bring almost half of the annual river streamflow. Among the feeders of the Prypyat the longest are the Styr and the Goryn with the Sluchcha, and among the feeders of the Desna - the Seym. The large right feeders are the Teteriv, the Ros, the Ingulets, the left feeders are the Sula, the Psyol, the Vorskla, the Oril, the Samara. Supply of the main river and its feeders is mixed. In spring snow thawing predetermines flooding, in summer and in winter mean water is observed, in autumn sometimes high waters occur. Freezing-over of the river lasts from December until March. The Dnieper has the largest annual river run-off (53,5 km3), therefore it is the important source of water supply for population and various areas of economy. The Dnieper waters “feed” hundreds of cities and villages located on the river banks. The river channels are directed for industrial needs of the Donbass and the Krivbass regions, irrigation of dry steppes of the Black Sea Coast and of the Crimea. The Dnieper is the important thoroughfare. The river is navigable along its whole length. The Dnieper is the important source of power supply. Its waters turn turbines of several hydroelectric power stations which develop the cheapest electric power. Nevertheless, due to formation of reservoirs large areas of fertile land were flooded, many settlements were transferred to new places, many cultural and historical artifacts were destroyed. Every year the pollution of the Dnieper waters increases. The pollution with radionuclides that penetrated into bottom sediments due to failure on the Chernobyl atomic power station in 1986 is especially dangerous. Therefore the Dnieper requires appropriate protection.

The Southern Bug is the second largest river in Ukraine according to its length (806 km) and the river basin area. It is the only largest river which completely collects its waters from the territory of Ukraine. Its largest feeders are the Synyukha and the Ingul. The river basin mostly lays within the Ukrainian board, therefore the river and its feeders are cataracted.
On separate sites there are canyons with granite banks. The Southern Bug runs into the estuary that is the branch of the Dniprovskyy estuary. The river is navigable only in its bottom stream. Several small hydroelectric power stations are constructed on the river, on its banks three regional centers are located.


The Dniester has length of 1 362 km with 705 km within Ukraine. Its source is on the slopes of the Carpathian mountains. In the upper courses it is the typical mountainous river, in the middle stream it turns into flat river with wide valley. Between the Podolska and the Prekarpatskaya heights the valley of Dniester is narrowed and obtains canyon-like forms. Its channel is extremely twisting. The Dniester runs into wide Dnistrovskyy estuary connected with its narrow mouth to the Black sea.

The largest feeders of the Dniester are the Stryy, the Limnytsya, the Seret, the Zbruch, the Smotrych, the Murafa. The Dniester and its feeders have a mixed type of water supply. Flooding comes in spring wh ereas high waters occur in summer and in autumn. The waters of the Dniester are used for water supply of built-up areas and enterprises, irrigation of fields. On the river the Hydroelectric power station is built. In middle and bottom streams the Dniester is navigable, nevertheless, nowadays the river is almost not used as the transport channel. On the banks of the Dniester such well-known historical and cultural centers as Galych, Khotyn, Bilgorod-Dnistrovskyy are located.
On the border of Ukraine with Romania the Danube flows with its bottom stream (with length of 175 km) — the second largest river of Europe according to its length (the general length is 2 960 km). It is one of the deepest rivers of Europe. It runs into the sea with several mouths. On the border of Ukraine the Kiliyskyy mouth is passing through the largest river run-off. The Kiliyskyy part of delta is actively put forward to the Black sea at the distance up to 180 m per year. The delta is rushy, cut with numerous channels, covered with lakes. These are the Danube River plavni - a unique place of wintering and rest during migration of many birds. The Danube has the mixed type of water supply with prevalence of rain waters. The river freezes only in times of very cold winters. The Tisa, the Prut, the Cheremosh and the Siret are the largest feeders of the Danube beginning in Ukraine. They begin in the Carpathian mountains wh ere they have a steep stream, great number of cataracts and falls, their waters bear a lot of silt and stones which are deposited in due course on plains. The Danube is the important transport channel of Europe.

THE RIVERS OF THE SEA OF AZOV BASIN. The largest river in the eastern part of Ukraine is the Severskyy Donets which is the feeder of the Don. The upper and the lower course of the river is in Russia, its length within Ukraine is over 670 km. It flows in a twisting channel and has wide broad valley. While crossing the Donetsk range the valley is narrowed, there are rocky slopes. The highest water level in the river occurs in spring, wh ereas in summer it considerably shallows. The largest feeders are the Oskil, the Aydar, the Lugan. On the river banks there are many cities and industrial enterprises which pollute it with waste and mine waters.

The middle-size rivers of the Sea of Azov basin according to their length are the Kalmius, the Berda, the Molochna, the Salgyr. They proceed in droughty areas and consequently are shallow, wh ereas the Salgyr in its bottom stream is dried up.


THE RIVERS OF THE BALTIC SEA BASIN AND OF INTERNAL RIVER RUN-OFF. The Western Bug and the Syan which are the feeders of the Visla flow into the Baltic sea. The Western Bug and its feeders begin and flow over flat territory wh ereas the Carpathian upper course of the Syan is mountainous.

  1. The majority of rivers of Ukraine belong to the basins of the Black and the Azov seas, much less of them belong to the Baltic sea basin and to internal river run-off.
  2. The Danube and the Dnieper rivers flow over the territory of Ukraine, being accordingly the second and the third largest rivers in Europe according to their length.
  3. The Dnieper is the largest river in Ukraine according to its length and basin area.
  4. The Southern Bug, the Dniester and the Severskyy Donets also are among the largest rivers of Ukraine.
