Radolfzeller Aach
The Radolfzeller Aach (also known as Hegauer Aach) is a right or north tributary of the Rhine in the south of Baden-Württemberg (Germany). It is approximately 32 km long. Course The source of the river is the ''Aachtopf'' in Aach, the largest spring in Germany, at a height of 475 m above sea level. The water emerges from a karst cave. About two thirds of the water originates in the headwaters of the Danube. Between Immendingen and Möhringen an der Donau and in Fridingen, water from the Danube disappears underground (this is known as the ''Danube Sinkhole''); this water reappears in the Aachtopf. The river first flows through a number of nature reserves in the Hegau area. This segment of the river is known as ''Hegauer Aach''. It then flows South to Singen, where it is known as ''Radolfzeller Aach''. The last six kilometers of the lower course flow through a nature reserve called ''Radolfzeller Aach Ried''. It flows into the northwestern part of Lake Unterse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alemannic German
Alemannic, or rarely Alemannish (''Alemannisch'', ), is a group of High German dialects. The name derives from the ancient Germanic tribal confederation known as the Alamanni ("all men"). Distribution Alemannic dialects are spoken by approximately ten million people in several countries: * In Europe: ** Switzerland: all German-speaking parts of the country except Samnaun ** Germany: centre and south of Baden-Württemberg, Swabia, and certain districts of Bavaria ** Austria: Vorarlberg, Reutte District of Tyrol ** Liechtenstein ** France: Alsace region ( Alsatian dialect) and in some villages of the Phalsbourg county, in Lorraine ** Italy: Gressoney-La-Trinité, Gressoney-Saint-Jean, Issime, Alagna Valsesia, Rimella and Formazza, in some other villages almost extinct *Outside Europe: ** United States: Allen and Adams County, Indiana, by the Amish there and also in their daughter settlements in Indiana and other U.S. states. ** Venezuela: Colonia Tovar ( Colonia Tova ...

Karst
Karst is a topography formed from the dissolution of soluble rocks such as limestone, Dolomite (rock), dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German language, German in the late 19th century, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snipe
A snipe is any of about 26 wading bird species in three genera in the family Scolopacidae. They are characterized by a very long, slender bill, eyes placed high on the head, and cryptic/ camouflaging plumage. The ''Gallinago'' snipes have a nearly worldwide distribution, the ''Lymnocryptes'' snipe is restricted to Asia and Europe and the '' Coenocorypha'' snipes are found only in the outlying islands of New Zealand. The four species of painted snipe are not closely related to the typical snipes, and are placed in their own family, the Rostratulidae. Behaviour Snipes search for invertebrates in the mud with a "sewing-machine" action of their long bills. The sensitivity of the bill is caused by filaments belonging to the fifth pair of nerves, which run almost to the tip and open immediately under the soft cuticle in a series of cells; a similar adaptation is found in sandpipers; this adaptation give this portion of the surface of the premaxillaries a honeycomb-like appeara ...

Sediment
Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice or by the force of gravity acting on the particles. For example, sand and silt can be carried in suspension in river water and on reaching the sea bed deposited by sedimentation; if buried, they may eventually become sandstone and siltstone ( sedimentary rocks) through lithification. Sediments are most often transported by water ( fluvial processes), but also wind (aeolian processes) and glaciers. Beach sands and river channel deposits are examples of fluvial transport and deposition, though sediment also often settles out of slow-moving or standing water in lakes and oceans. Desert sand dunes and loess are examples of aeolian transport and deposition. Glacial moraine deposits and till are ice-transported sediments. Classification Sediment can be classified based on its grain size, grain s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nature Restoration
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-So ...

Hydropower
Hydropower (from el, ὕδωρ, "water"), also known as water power, is the use of falling or fast-running water to produce electricity or to power machines. This is achieved by converting the gravitational potential or kinetic energy of a water source to produce power. Hydropower is a method of sustainable energy production. Hydropower is now used principally for hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity. Hydropower is an attractive alternative to fossil fuels as it does not directly produce carbon dioxide or other atmospheric pollutants and it provides a relatively consistent source of power. Nonetheless, it has economic, sociological, and environmental downsides and requires a sufficiently energetic source of water, such as a river or elevated lake. International institutions such as the World Bank view hydropower as a low-carbon means for economic development. Since ancient t ...

Watermill
A watermill or water mill is a mill that uses hydropower. It is a structure that uses a water wheel or water turbine to drive a mechanical process such as milling (grinding), rolling, or hammering. Such processes are needed in the production of many material goods, including flour, lumber, paper, textiles, and many metal products. These watermills may comprise gristmills, sawmills, paper mills, textile mills, hammermills, trip hammering mills, rolling mills, wire drawing mills. One major way to classify watermills is by wheel orientation (vertical or horizontal), one powered by a vertical waterwheel through a gear mechanism, and the other equipped with a horizontal waterwheel without such a mechanism. The former type can be further divided, depending on where the water hits the wheel paddles, into undershot, overshot, breastshot and pitchback (backshot or reverse shot) waterwheel mills. Another way to classify water mills is by an essential trait about their location: tide mills ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. 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 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 a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside 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 simi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hegau
The Hegau is an extinct volcanic landscape in southern Germany extending around the industrial city of Singen (Hohentwiel), between Lake Constance in the east, the Rhine River in the south, the Danube River in the north and the Randen (mountain range), Randen—as the southwestern mountains of the Swabian Jura are called—in the west. It was first mentioned in A.D. 787 in the Latinised form ''in pago Egauinsse''.Albert Krieger: Topographisches Wörterbuch des Großherzogtums Baden, Vol. 1, p. 882 (1904)' The most famous sight of the Hegau is the Hohentwiel, a volcanic stub. On top of the mountain lies Hohentwiel fortress. The Hohentwiel is the southernmost of a row of volcanic stubs in the Hegau, including the Hohenkrähen, the Hohenstoffeln, and the Hohenhewen.

Danube Sinkhole
Sinkhole in the Danube near Möhringen Schematic of the sinkhole locations and the route to Aachtopf Completely dry Danube riverbed right , Sink hole on the southern bank of the Danube, at the main sinkhole site below Immendingen Sign in Immendingen. Translation: "Sinkhole – Here the Danube sinks dry on about 155 days per year" The Danube Sinkhole (german: Donauversinkung or ) is an incipient underground stream capture in the Upper Danube Nature Park. Between Immendingen and Möhringen and also near Fridingen ( Tuttlingen), the water of the Danube sinks into the riverbed in various places. The main sinkhole is next to a field named ''Brühl'' between Immendingen and Möhringen. The term "sinking" is more accurate than "seeping", because, instead of just distributing into the soil, the Danube's water flows through caverns to the Aachtopf, where it emerges as the river Radolfzeller Aach, a tributary of the Rhine.
