900-540: A drainage boundary is referred to as watershed delineation . Finding the area and extent of a drainage basin is an important step in many areas of science and engineering. Most of the water that discharges from the basin outlet originated as precipitation falling on the basin. A portion of the water that enters the groundwater system beneath the drainage basin may flow towards the outlet of another drainage basin because groundwater flow directions do not always match those of their overlying drainage network. Measurement of

The first great Russian novelist was Nikolai Gogol . Then came Ivan Turgenev , who mastered both short stories and novels. Fyodor Dostoevsky and Leo Tolstoy soon became internationally renowned. Ivan Goncharov

7500-561: The general "East European" gene cluster with the rest East and West Slavs (Poles, Czechs and Slovaks), as well as the non-Slavic Hungarians and Aromanians . Genetically, East Slavs are quite similar to West Slavs; such genetic similarity is somewhat unusual for genetics with such a wide settlement of the Slavs, especially Russians. The high unity of the autosomal markers of the East Slavic populations and their significant differences from

7600-567: The greatest portion of western Sub-Saharan Africa , as well as Western Sahara and part of Morocco . The two major mediterranean seas of the world also flow to the Atlantic. The Caribbean Sea and Gulf of Mexico basin includes most of the U.S. interior between the Appalachian and Rocky Mountains , a small part of the Canadian provinces of Alberta and Saskatchewan , eastern Central America ,

7700-435: The ground and along rivers it can pick up nutrients , sediment , and pollutants . With the water, they are transported towards the outlet of the basin, and can affect the ecological processes along the way as well as in the receiving water body . Modern use of artificial fertilizers , containing nitrogen (as nitrates ), phosphorus , and potassium , has affected the mouths of drainage basins. The minerals are carried by

7800-744: The ground at its terminus, the area can go by several names, such playa, salt flat, dry lake , or alkali sink . The largest endorheic basins are in Central Asia , including the Caspian Sea , the Aral Sea , and numerous smaller lakes. Other endorheic regions include the Great Basin in the United States, much of the Sahara Desert , the drainage basin of the Okavango River ( Kalahari Basin ), highlands near

7900-494: The groundbreaking Soviet montage theory of film editing at the world's first film school , the All-Union Institute of Cinematography . Dziga Vertov 's " Kino-Eye " theory had a huge impact on the development of documentary filmmaking and cinema realism. Many Soviet socialist realism films were artistically successful, including Chapaev , The Cranes Are Flying , and Ballad of a Soldier . The 1960s and 1970s saw

8000-690: The history of Russia became essentially the history of the Soviet Union , effectively an ideologically based state roughly conterminous with the Russian Empire before the 1918 Treaty of Brest-Litovsk . From its first years, government in the Soviet Union based itself on the one-party rule of the Communists, as the Bolsheviks called themselves, beginning in March 1918. The approach to the building of socialism, however, varied over different periods in Soviet history: from

8100-619: The islands of the Caribbean and the Gulf, and a small part of northern South America. The Mediterranean Sea basin, with the Black Sea , includes much of North Africa , east-central Africa (through the Nile River ), Southern , Central, and Eastern Europe , Turkey , and the coastal areas of Israel , Lebanon , and Syria . The Arctic Ocean drains most of Western Canada and Northern Canada east of

8200-417: The later border changes, but was rejected and cancelled by Russia on June 27, 2005 because references to Soviet occupation were added. In 2010, 19,443 inhabitants of the district were ethnic Russians , 174 Estonians and 115 Setos , a Finnic minority endemic to the region of Setomaa , of which Pechory is the cultural capital. In 2013, the district had a low unemployment rate of 2.54%. The part of

8300-482: The leading theoretician of Theosophy , and co-founded the Theosophical Society . Vladimir Lenin , a major revolutionary, developed a variant of communism known as Leninism . Leon Trotsky , on the other hand, founded Trotskyism . Alexander Zinoviev was a prominent philosopher in the second half of the 20th century. Mikhail Lomonosov proposed the conservation of mass in chemical reactions , discovered

8400-506: The most water, from most to least, are the Amazon, Ganges , and Congo rivers. Endorheic basin are inland basins that do not drain to an ocean. Endorheic basins cover around 18% of the Earth's land. Some endorheic basins drain to an Endorheic lake or Inland sea . Many of these lakes are ephemeral or vary dramatically in size depending on climate and inflow. If water evaporates or infiltrates into

8500-578: The neighboring Finnic, Turkic and Caucasian peoples were revealed. Northern Russians , according to mtDNA , Y chromosome and autosomal marker CCR5de132, are included in the "North European" gene cluster (the Poles , the Balts , Germanic and Baltic Finnic peoples ). Consequently, the already existing biologo-genetic studies have made all hypotheses about the mixing of the Russians with non-Slavic ethnic groups or their "non-Slavism" obsolete or pseudoscientific. At

8600-506: The presence of a Finnic substrate in modern Russian population. Outside archaeological remains, little is known about the predecessors to Russians in general prior to 859 AD, when the Primary Chronicle starts its records. By 600 AD, the Slavs are believed to have split linguistically into southern , western , and eastern branches. The Rus' state was established in northern Russia in

8700-418: The rainfall on the area of land included in its polygon. These polygons are made by drawing lines between gauges, then making perpendicular bisectors of those lines form the polygons. The isohyetal method involves contours of equal precipitation are drawn over the gauges on a map. Calculating the area between these curves and adding up the volume of water is time-consuming. Isochrone maps can be used to show

8800-625: The responsibility of the countries sharing it. Nile Basin Initiative , OMVS for Senegal River , Mekong River Commission are a few examples of arrangements involving management of shared river basins. Management of shared drainage basins is also seen as a way to build lasting peaceful relationships among countries. The catchment is the most significant factor determining the amount or likelihood of flooding . Catchment factors are: topography , shape, size, soil type, and land use (paved or roofed areas). Catchment topography and shape determine

8900-461: The river rather than being absorbed by the ground. If the surface is impermeable the precipitation will create surface run-off which will lead to higher risk of flooding; if the ground is permeable, the precipitation will infiltrate the soil. Land use can contribute to the volume of water reaching the river, in a similar way to clay soils. For example, rainfall on roofs, pavements , and roads will be collected by rivers with almost no absorption into

9000-602: The same time, the long-standing identification of the Northern Russian and Southern Russian ethnographic groups by ethnologists was confirmed. The previous conclusions of physical anthropologists, historians and linguists (see, in particular, the works of the academician Valentin Yanin ) about the proximity of the ancient Novgorod Slavs and their language not to the East, but to west Baltic Slavs . As can be seen from genetic resources ,

9100-418: The speed with which the runoff reaches a river. A long thin catchment will take longer to drain than a circular catchment. Size will help determine the amount of water reaching the river, as the larger the catchment the greater the potential for flooding. It is also determined on the basis of length and width of the drainage basin. Soil type will help determine how much water reaches the river. The runoff from

9200-415: The time taken for rain to reach the river, while catchment size, soil type, and development determine the amount of water to reach the river. Generally, topography plays a big part in how fast runoff will reach a river. Rain that falls in steep mountainous areas will reach the primary river in the drainage basin faster than flat or lightly sloping areas (e.g., > 1% gradient). Shape will contribute to

9300-477: The time taken for runoff water within a drainage basin to reach a lake, reservoir or outlet, assuming constant and uniform effective rainfall. Drainage basins are the principal hydrologic unit considered in fluvial geomorphology . A drainage basin is the source for water and sediment that moves from higher elevation through the river system to lower elevations as they reshape the channel forms. Drainage basins are important in ecology . As water flows over

9400-509: The way for the Naryshkin baroque of the 1690s. After the reforms of Peter the Great, Russia's architecture became influenced by Western European styles. The 18th-century taste for Rococo architecture led to the splendid works of Bartolomeo Rastrelli and his followers. During the reign of Catherine the Great, Saint Petersburg was transformed into an outdoor museum of Neoclassical architecture . During Alexander I 's rule, Empire style became

9500-641: The world's land drains to the Atlantic Ocean . In North America , surface water drains to the Atlantic via the Saint Lawrence River and Great Lakes basins, the Eastern Seaboard of the United States, the Canadian Maritimes , and most of Newfoundland and Labrador . Nearly all of South America east of the Andes also drains to the Atlantic, as does most of Western and Central Europe and

9600-538: The year 862, which was ruled by the Varangians . Staraya Ladoga and Novgorod became the first major cities of the new union of immigrants from Scandinavia with the Slavs and Finns . In 882, the prince Oleg seized Kiev , thereby uniting the northern and southern lands of the East Slavs under one authority. The state adopted Christianity from the Byzantine Empire in 988. Kievan Rus' ultimately disintegrated as

9700-473: Was abolished and split between Pechorsky and Palkinsky Districts. After Estonian independence was re-established in 1991, the district was claimed by Estonia because of the Treaty of Tartu, in which the Soviet Union had relinquished further claims to Estonian territory. In November 1995, Estonia reportedly dropped this claim. A newer Estonian-Russian Border Treaty was signed by Estonia on May 18, 2005, reflecting

9800-433: Was best known for having identified the centers of origin of cultivated plants. Many famous Russian scientists and inventors were émigrés . Igor Sikorsky was an aviation pioneer . Vladimir Zworykin was the inventor of the iconoscope and kinescope television systems. Theodosius Dobzhansky was the central figure in the field of evolutionary biology for his work in shaping the modern synthesis . George Gamow

9900-420: Was established. In 1776, Pechory was granted town status and Pechorsky Uyezd was established, but in 1797, Pechorsky Uyezd was abolished, and the area became a part of Pskovsky Uyezd of Pskov Governorate. During the last year of World War I, from February to December 1918, the town of Pechory was occupied by German forces. The town was subsequently captured by Estonian forces on March 29, 1919, during

10000-573: Was one of the foremost advocates of the Big Bang theory. Konstantin Tsiolkovsky is called the father of theoretical astronautics , whose works had inspired leading Soviet rocket engineers, such as Valentin Glushko , and many others. In 1961, the first human trip into space was successfully made by Yuri Gagarin . In 1963, Valentina Tereshkova became the first and youngest woman in space , having flown
