77-473: The Kabaty Woods lie on flat ground, except for an east part comprising hills of dune origin. A striking landscape accent is a high escarpment above the glacial valley of the Vistula River , which forms the reserve's eastern border. The Kabaty Woods are a reservoir of fresh air for the surrounding housing developments, as well as a popular place of rest and recreation. The Woods are easily reached via buses and

154-427: A hierarchical pattern . Other terms for a drainage basin are catchment area , catchment basin , drainage area , river basin , water basin , and impluvium . In North America, they are commonly called a watershed , though in other English-speaking places, "watershed" is used only in its original sense, that of the drainage divide line. A drainage basin's boundaries are determined by watershed delineation ,

231-437: A common task in environmental engineering and science. In a closed drainage basin, or endorheic basin , rather than flowing to the ocean, water converges toward the interior of the basin, known as a sink , which may be a permanent lake, a dry lake , or a point where surface water is lost underground . Drainage basins are similar but not identical to hydrologic units , which are drainage areas delineated so as to nest into

308-449: A drainage basin, and there are different ways to interpret that data. In the unlikely event that the gauges are many and evenly distributed over an area of uniform precipitation, using the arithmetic mean method will give good results. In the Thiessen polygon method, the drainage basin is divided into polygons with the rain gauge in the middle of each polygon assumed to be representative for

385-540: 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

462-745: A good and well-measured proxy for the economic growth of the Commonwealth. The owner of a folwark usually signed a contract with the merchants of Gdańsk, who controlled 80% of this inland trade, to ship the grain to Gdańsk. Many rivers in the Commonwealth were used for shipping, including the Vistula, which had a relatively well-developed infrastructure, with river ports and granaries . Most river shipping travelled north, with southward transport being less profitable, and barges and rafts often being sold off in Gdańsk for lumber. In order to arrest recurrent flooding on

539-581: A multi-level hierarchical drainage system . Hydrologic units are defined to allow multiple inlets, outlets, or sinks. In a strict sense, all drainage basins are hydrologic units but not all hydrologic units are drainage basins. About 48.71% of 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,

616-568: A project was undertaken to increase the traffic-carrying capacity of the river upstream of Warsaw by building a number of locks in and around Kraków , this project was not extended further, so that navigability of the Vistula remains limited. The potential of the river would increase considerably if a restoration of the east–west connection via the Narew – Bug – Mukhovets – Pripyat – Dnieper waterways were considered. The shifting economic importance of parts of Europe may make this option more likely. Vistula

A basin is separated from adjacent basins by a perimeter, the drainage divide , made up of a succession of elevated features, such as ridges and hills . A basin may consist of smaller basins that merge at river confluences , forming

847-480: Is referred to as " watershed management ". In Brazil , the National Policy of Water Resources, regulated by Act n° 9.433 of 1997, establishes the drainage basin as the territorial division of Brazilian water management. When a river basin crosses at least one political border, either a border within a nation or an international boundary, it is identified as a transboundary river . Management of such basins becomes

924-600: Is the Dead Sea . Drainage basins have been historically important for determining territorial boundaries, particularly in regions where trade by water has been important. For example, the English crown gave the Hudson's Bay Company a monopoly on the fur trade in the entire Hudson Bay basin, an area called Rupert's Land . Bioregional political organization today includes agreements of states (e.g., international treaties and, within

1001-562: Is the longest river in Poland and the ninth-longest in Europe, at 1,047 kilometres (651 miles) in length. Its drainage basin , extending into three other countries apart from Poland, covers 193,960 km (74,890 sq mi), of which 168,868 km (65,200 sq mi) is in Poland. The Vistula rises at Barania Góra in the south of Poland, 1,220 meters (4,000 ft) above sea level in

1078-695: Is the northern part of the proposed E40 waterway , continuing eastward into the Bug River , linking the Baltic Sea to the Black Sea . Large parts of the Vistula Basin were occupied by the Iron Age Lusatian and Przeworsk cultures in the first millennium BC. Genetic analysis indicates that there has been an unbroken genetic continuity of the inhabitants over the last 3,500 years. The Vistula Basin along with

1155-682: The African Great Lakes , the interiors of Australia and the Arabian Peninsula , and parts in Mexico and the Andes . Some of these, such as the Great Basin, are not single drainage basins but collections of separate, adjacent closed basins. In endorheic bodies of water where evaporation is the primary means of water loss, the water is typically more saline than the oceans. An extreme example of this

1232-584: 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 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

1309-531: The Gdańsk Bay of the Baltic Sea with a delta of six main branches ( Leniwka , Przekop , Śmiała Wisła , Martwa Wisła , Nogat and Szkarpawa ). The river has many associations with Polish culture , history and national identity. It is Poland's most important waterway and natural symbol , flowing notably through Kraków and the capital Warsaw , and the phrase "Country upon Vistula" ( Polish : kraj nad Wisłą ) can be synonymous with Poland. Historically,

1386-718: The Mississippi (3.22 million km ), and the Río de la Plata (3.17 million km ). The three rivers that drain 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

The Arctic Ocean drains most of Western Canada and Northern Canada east of the Continental Divide , northern Alaska and parts of North Dakota , South Dakota , Minnesota , and Montana in the United States, the north shore of the Scandinavian peninsula in Europe, central and northern Russia, and parts of Kazakhstan and Mongolia in Asia , which totals to about 17% of

1540-584: The North Sea somewhere at the latitude of contemporary Scotland. The climate of the Vistula valley, its plants, animals, and its very character changed considerably during the process of glacial retreat. Vistula is navigable from the Baltic Sea to Bydgoszcz (where the Bydgoszcz Canal joins the river). It can accommodate modest river vessels of CEMT class II. Farther upstream the river depth lessens. Although

During the German occupation of Poland ( World War II ), it was the site of a massacre of 200 Poles , perpetrated by the Germans in December 1939 and January 1940 as part of the genocidal Intelligenzaktion campaign. The Kabaty Woods are named after Kabaty , a village that once stood on the picturesque banks of the Vistula River. The woods reserve has subsequently been named for Stefan Starzyński , Warsaw's patriotic mayor who in 1938 secured its purchase from private owners. During World War II , Starzyński

1848-487: The 16th century most of the grain exported was leaving Poland through Gdańsk, which because of its location at the end of the Vistula and its tributary waterway and of its Baltic seaport trade role became the wealthiest, most highly developed, and by far the largest centre of crafts and manufacturing, and the most autonomous of the Polish cities. Other towns were negatively affected by Gdańsk's near-monopoly in foreign trade. During

1925-692: The Alpine zone to which the Alps and the Carpathians belong. The Vistula begins in the Carpathian mountains. The run and character of the river were shaped by ice sheets flowing down from the Scandinavian peninsula. The last ice sheet entered the area of Poland about 20,000 years ago. During periods of warmer weather, the ancient Vistula, "Pra-Wisła", searched for the shortest way to the sea—thousands of years ago it flowed into

2002-758: The Andes. The Indian Ocean 's drainage basin also comprises about 13% of Earth's land. It drains the eastern coast of Africa, the coasts of the Red Sea and the Persian Gulf , the Indian subcontinent , Burma, and most parts of Australia . The five largest river basins (by area), from largest to smallest, are those of the Amazon (7 million km ), the Congo (4 million km ), the Nile (3.4 million km ),

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 , 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

2156-527: The Baltic area as a centre of merchants and trade and as a port city. At this time the surrounding lands were inhabited by Pomeranians , but Gdańsk soon became a starting point for German settlement of the largely fallow Vistulan country. Before its peak in 1618, trade increased by a factor of 20 from 1491. This factor is evident when looking at the tonnage of grain traded on the river in the key years of: 1491: 14,000; 1537: 23,000; 1563: 150,000; 1618: 310,000. In

According to the most popular variant, popularized by the 15th-century historian Jan Długosz , Wanda, daughter of King Krak , became queen of the Poles upon her father's death. She refused to marry a German prince Rytigier (Rüdiger), who took offence and invaded Poland, but was repelled. Wanda however committed suicide , drowning in the Vistula River, to ensure he would not invade her country again. For hundreds of years

2310-564: The River Vistula and its valley spans over 2 million years. The river is connected to the geological period called the Quaternary , in which distinct cooling of the climate took place. In the last million years, an ice sheet entered the area of Poland eight times, bringing along with it changes of reaches of the river. In warmer periods, when the ice sheet retreated, the Vistula deepened and widened its valley. The river took its present shape within

The Baltic Sea– Vistula– Dnieper– Black Sea route with its rivers was one of the most ancient trade routes, the Amber Road , on which amber and other items were traded from Northern Europe to Greece, Asia, Egypt , and elsewhere. The Vistula estuary

2618-453: The Vistula below this point is sometimes called the Leniwka . Various causes (rain, snow melt, ice jams ) have caused many severe floods of the Vistula over the centuries. Land in the area was sometimes depopulated by severe flooding, and later had to be resettled. See (Figure 7, on page 812 at History of floods on the River Vistula ) for a reconstruction map of the delta area as it was around

The Polish September campaign included battles over control of the mouth of the Vistula, and of the city of Gdańsk, close to

3080-430: The discharge of water from a basin may be made by a stream gauge located at the basin's outlet. Depending on the conditions of the drainage basin, as rainfall occurs some of it seeps directly into the ground. This water will either remain underground, slowly making its way downhill and eventually reaching the basin, or it will permeate deeper into the soil and consolidate into groundwater aquifers. As water flows through

3157-441: The drainage area is dependent on the soil type. Certain soil types such as sandy soils are very free-draining, and rainfall on sandy soil is likely to be absorbed by the ground. However, soils containing clay can be almost impermeable and therefore rainfall on clay soils will run off and contribute to flood volumes. After prolonged rainfall even free-draining soils can become saturated , meaning that any further rainfall will reach

This can cause eutrophication where plant growth is accelerated by the additional material. Because drainage basins are coherent entities in a hydrological sense, it has become common to manage water resources on the basis of individual basins. In the U.S. state of Minnesota , governmental entities that perform this function are called " watershed districts ". In New Zealand, they are called catchment boards. Comparable community groups based in Ontario, Canada, are called conservation authorities . In North America, this function

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

3619-492: The lands of the Rhine , Danube , Elbe , and Oder came to be called Magna Germania by Roman authors of the first century AD. This does not imply that the inhabitants were " Germanic peoples " in the modern sense of the term; Tacitus , when describing the Venethi , Peucini and Fenni , wrote that he was not sure if he should call them Germans, since they had settlements and they fought on foot, or rather Sarmatians since they have some similar customs to them. Ptolemy , in

At present, along with the Vistula valley, erosion of the banks and collecting of new deposits are still occurring. As the principal river of Poland, the Vistula is also in the centre of Europe. Three principal geographical and geological land masses of the continent meet in its river basin: the Eastern European Plain , Western Europe, and

3773-414: The lower Vistula, the Prussian government in 1889–95 constructed an artificial channel about 12 kilometres (7 miles) east of Gdańsk (German name: Danzig )—known as the Vistula Cut (German: Weichseldurchstich ; Polish: Przekop Wisły )—that acted as a huge sluice, diverting much of the Vistula flow directly into the Baltic . As a result, the historic Vistula channel through Gdańsk lost much of its flow and

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

4081-400: The reign of Stephen Báthory Poland ruled two main Baltic Sea ports: Gdańsk controlling the Vistula river trade and Riga controlling the Western Dvina trade. Both cities were among the largest in the country. Around 70% the exports from Gdańsk were of grain. Grain was also the largest export commodity of the Polish–Lithuanian Commonwealth . The volume of traded grain can be considered

4158-572: 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

4235-488: The rich undergrowth includes rare plants and protected species such as Lilium martagon , Lycopodium clavatum , Carex brizoides , as well as lilies-of-the valley . The rich plant environment favors a wealth of animals — deer, wild boar, fox, badger, weasel, pine marten, hedgehog — and various birds: buzzard, Eurasian hobby, kestrel, sparrow hawk, tawny owl, long-eared owl, green woodpecker and black woodpecker, wilson, crossbill, bullfinch and others. Particularly notable are

4312-491: The river Vistla (4.81, 4.97, 4.100). The root of the name Vistula is often thought to come from Proto-Indo-European * weys- : 'to ooze, flow slowly' (cf. Sanskrit अवेषन् avēṣan "they flowed", Old Norse veisa "slime"), and similar elements appear in many European river-names (e.g. Svislach (Berezina) , Svislach (Neman) , Weser , Viešinta ). In writing about the river and its peoples, Ptolemy uses Greek spelling: Ouistoula . Other ancient sources spell

4389-431: The river basin (right-hand to left-hand side) is 73–27%. The most recent glaciation of the Pleistocene epoch , which ended around 10,000 BC, is called the Vistulian glaciation or Weichselian glaciation in regard to north-central Europe. The river forms a wide delta called Żuławy Wiślane , or the "Vistula Fens" in English. The delta currently starts around Biała Góra near Sztum , about 50 km (31 mi) from

4466-478: The river basin ranges from 100 to 300 metres (328 to 984 feet) in altitude. The highest point of the river basin is at 2,655 metres (8,711 feet) (Gerlach Peak in the Tatra mountains ). One of the features of the river basin of the Vistula is its asymmetry—in great measure resulting from the tilting direction of the Central European Lowland toward the northwest, the direction of the flow of glacial waters, and considerable predisposition of its older base. The asymmetry of

4543-418: The river delta. During the Invasion of Poland (1939) , after the initial battles in Pomerelia , the remains of the Polish Army of Pomerania withdrew to the southern bank of the Vistula. After defending Toruń for several days, the army withdrew further south under pressure of the overall strained strategic situation, and took part in the main battle of Bzura . The Auschwitz complex of concentration camps

4620-461: 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

4697-405: The river was also important for the Baltic and German ( Prussian ) peoples. The Vistula has given its name to the last glacial period that occurred in northern Europe, approximately between 100,000 and 10,000 BC, the Weichselian glaciation . The name Vistula first appears in the written record of Pomponius Mela (3.33) in AD   40. Pliny in AD   77 in his Natural History names

Both are on the western slope of Barania Góra in the Silesian Beskids in Poland. Vistula can be divided into three parts: upper, from its sources to Sandomierz ; central, from Sandomierz to

5159-418: 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

5236-431: The territory of interbellum Poland was drained northward into the Baltic Sea by the Vistula (total area of drainage basin of the Vistula within boundaries of the Second Polish Republic was 180,300 km (69,600 sq mi), the Niemen (51,600 km  [19,900 sq mi]), the Oder (46,700 km  [18,000 sq mi]) and the Daugava (10,400 km  [4,000 sq mi]). In 1920

5313-415: 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

5390-477: 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 .

Its basin includes much of China, eastern and southeastern Russia, Japan, the Korean Peninsula , most of Indochina, Indonesia and Malaysia, the Philippines, all of the Pacific Islands , the northeast coast of Australia , and Canada and the United States west of the Continental Divide (including most of Alaska), as well as western Central America and South America west of

5621-562: The year 1300: note much more water in the area, and the west end of the Vistula Lagoon (Frisches Haff) was bigger and nearly continuous with the Drausen See . As with some aggrading rivers, the lower Vistula has been subject to channel changing. Near the sea, the Vistula was diverted sideways by coastal sand as a result of longshore drift and split into an east-flowing branch (the Elbing (Elbląg) Vistula, Elbinger Weichsel, Szkarpawa, flows into
