It starts at the base of the Irazú Volcano , passing through the east side of the Central Valley , and flows through the Orosí and Turrialba Valleys. After reaching the Caribbean coastal plains it joins the Parismina River and forms what is called

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 ,

This awakening was accelerated by writers and other intellectuals, who recognized the societal paralysis of decaying dictatorships and felt compelled to speak up against Soviet oppression. In

There were also various resistance movements around Otto von Habsburg that pursued this goal. The group around the Austrian priest Heinrich Maier also planned in this direction, which also successfully helped the Allies to wage war by, among other things, forwarding production sites and plans for V-2 rockets , Tiger tanks and aircraft to

Besides Austria, Switzerland and Yugoslavia, only the marginal European states of Cyprus , Finland , Malta and Sweden preserved their political sovereignty to a certain degree, being left out of any military alliances in Europe. The opening of the Iron Curtain between Austria and Hungary at
534-656: A buffer zone between these regions. In the early nineteenth century, the terms "Middle" or "Central" Europe (known as "Mitteleuropa" in German and "Europe centrale" in French) were introduced in geographical scholarship in both German and French languages. At first, these terms were linked to the regions spanning from the Pyrenees to the Danube, which, according to German authors, could be united under German authority. However, after

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

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
801-540: 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

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,

Before 1870, the industrialization that had started to develop in Northwestern and Central Europe and the United States did not extend in any significant way to the rest of the world. Even in Eastern Europe , industrialization lagged far behind. Russia , for example, remained largely rural and agricultural, and its autocratic rulers kept

Johnson's study on Central Europe received acclaim and positive reviews in the scientific community.

At times, the term "Central Europe" denotes a geographic definition as the Danube region in the heart of the continent, including the language and culture areas which are today included in the states of Bulgaria , Croatia , the Czech Republic , Hungary , Moldova , Poland , Romania , Serbia , Slovakia , Slovenia and usually also Austria and Germany.

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

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

Both Adolf Hitler and Joseph Stalin diametrically opposed the centuries-old Habsburg principles of "live and let live" with regard to ethnic groups, peoples, minorities, religions, cultures and languages and tried to assert their own ideologies and power interests in Central Europe. There were various Allied plans for state order in Central Europe for post-war. While Stalin tried to get as many states under his control as possible, Winston Churchill preferred

While the Avars dominated the east of what is now Austria, its north and south were under Germanic and Slavic influence, respectively. Meanwhile, the territories now comprising Germany and Switzerland were under the influence of the Merovingian dynasty , and later the Carolingian dynasty . Various Slavic tribes that inhabited eastern Central Europe established settlements during this period, primarily in present-day Croatia, Czech Republic, Poland, Slovakia and Slovenia.

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

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

Isochrone maps can be used to show

In this case Austria, Germany and Switzerland are often placed in Western Europe, while Croatia, the Czech Republic, Hungary, Lithuania, Poland, Slovakia and Slovenia are placed in Eastern Europe. Croatia

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

Before World War I, it embraced mainly German-speaking states, with non-German speaking territories being an area of intended German penetration and domination – German leadership was to be the 'natural' result of economic dominance. Post-war, the Eastern part of Central Europe
6764-461: 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
6853-418: 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.
