Untersee (Lake Constance)
The ''Untersee'' (German language, German for ''Lower Lake''), also known as Lower Lake Constance, is the smaller of the two lakes that together form Lake Constance. The boundary between Switzerland and Germany runs through it. The lake surrounds several islands, the largest being Reichenau Island. Geography The Lower Lake Constance measures and is situated about lower than the Obersee (Lake Constance), Obersee. The Roman Empire, Romans called it ''Lacus Acronius''. In the Middle Ages, the Upper Lake was called ''Bodamicus Lacus'', or ''Bodensee'' in German. At some point in time, this term began to include the Lower Lake, and a new term "Upper Lake" (in German: ''Obersee (Lake Constance), Obersee''), was introduced for the larger lake. The main tributaries are the ''Seerhein'' and Radolfzeller Aach. The source of the latter is the Aachtopf, a karst spring whose waters mainly derive from the Danube Sinkhole, making the Danube indirectly a tributary of ''Untersee'' and ...

List Of Islands Of Switzerland ...
__NOTOC__ This is a list of islands of Switzerland. Switzerland is a landlocked country, hence all Swiss islands are located in lakes or rivers. This list also includes islands in artificial lakes (*). In these cases, the water levels may drop by a few metres at some periods of the year, thereby turning some islands into peninsulas.

Isobath
A bathymetric chart is a type of isarithmic map that depicts the submerged bathymetry and physiographic features of ocean and sea bottoms. Their primary purpose is to provide detailed depth contours of ocean topography as well as provide the size, shape and distribution of underwater features. Topographic maps display elevation above ground (topography) and are complementary to bathymetric charts. Bathymetric charts showcase depth using a series of lines and points at equal intervals, called depth contours or isobaths (a type of contour line). A closed shape with increasingly smaller shapes inside of it can indicate an ocean trench or a seamount, or underwater mountain, depending on whether the depths increase or decrease going inward. Bathymetric surveys and charts are associated with the science of oceanography, particularly marine geology, and underwater engineering or other specialized purposes. Bathymetric data used to produce charts can also be converted to bathymet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Former Islands
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being used in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose cone to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until t ...

Wave
In physics, mathematics, engineering, and related fields, a wave is a propagating dynamic disturbance (change from List of types of equilibrium, equilibrium) of one or more quantities. ''Periodic waves'' oscillate repeatedly about an equilibrium (resting) value at some frequency. When the entire waveform moves in one direction, it is said to be a travelling wave; by contrast, a pair of superposition principle, superimposed periodic waves traveling in opposite directions makes a ''standing wave''. In a standing wave, the amplitude of vibration has nulls at some positions where the wave amplitude appears smaller or even zero. There are two types of waves that are most commonly studied in classical physics: mechanical waves and electromagnetic waves. In a mechanical wave, Stress (mechanics), stress and Strain (mechanics), strain fields oscillate about a mechanical equilibrium. A mechanical wave is a local deformation (physics), deformation (strain) in some physical medium that propa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sand Bank
In oceanography, geomorphology, and geoscience, a shoal is a natural submerged ridge, bank, or bar that consists of, or is covered by, sand or other unconsolidated material, and rises from the bed of a body of water close to the surface or above it, which poses a danger to navigation. Shoals are also known as sandbanks, sandbars, or gravelbars. Two or more shoals that are either separated by shared troughs or interconnected by past or present sedimentary and hydrographic processes are referred to as a shoal complex.Neuendorf, K.K.E., J.P. Mehl Jr., and J.A. Jackson, eds. (2005) ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. The term ''shoal'' is also used in a number of ways that can be either similar to, or quite different from, how it is used in geologic, geomorphic, and oceanographic literature. Sometimes, the term refers to either any relatively shallow place in a stream, lake, sea, or other body of water; a rocky area ...

Triboldingerbohl
Triboldingerbohl, also known as Triboltingen or großes Bohl or Langenrain, is the fourth largest island of Lake Constance, with an area of . It is long and up to wide. It is located in the easternmost part of the Untersee (Lake Constance), near the point where the Seerhein flows into the lake. This part of the lake is also known as the Rheinsee. It belongs to the Wollmatinger Ried nature conservation area; administratively it belongs to the district ''industrial area'' of the City of Constance. Until 1934, it belonged to the municipality of Wollmatingen, which was then annexed by Constance. Triboldingerbohl lies southeast of Reichenau Island and from the dam that connects Reichenau to the mainland. The area between Triboldingerbohl island and the Reichenau dam is called ''Ermatinger pool'' and is an ecologically important shallow-water zone. Triboldingerbohl is uninhabited. It is a bird sanctuary. It takes its name from the former Swiss municipality Triboltingen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hectare
The hectare (; SI symbol: ha) is a non-SI metric unit of area equal to a square with 100-metre sides (1 hm2), that is, square metres (), and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about and one hectare contains about . In 1795, when the metric system was introduced, the ''are'' was defined as 100 square metres, or one square decametre, and the hectare (" hecto-" + "are") was thus 100 ''ares'' or km2 ( square metres). When the metric system was further rationalised in 1960, resulting in the International System of Units (), the ''are'' was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI and whose use is "expected to continue indefinitely". Though the dekare/decare daa () and are (100 m2) are not officially "accepted for use", they are still used in some contexts. Description The hectare (), although not a unit of SI, is ...

Shallow (underwater Relief)
Shallow is an elevation of the bottom in the sea, river, lake, which impedes navigation. It is a type of an underwater relief where the depth of the water is low compared to that of the surrounding points. Usually formed by sand or pebble deposits, can also be of volcanic origin or the result of human or animal activities. Stranded near the shore of a reservoir or watercourse is called a shoal; the shallow ocean area adjacent to the mainland is the continental shelf. Shallows can be permanently hidden under water or appear on the surface of the water periodically (for example, during low tide in the seas, changes in the water level in rivers from water content) in the form of islands, sediments, side streams, spits, etc. On river shoals, if possible, to cross the river on foot, or by land transport, arrange fords.

Ermatingen
Ermatingen is a Municipalities of Switzerland, municipality in the district of Kreuzlingen (district), Kreuzlingen in the Cantons of Switzerland, canton of Thurgau in Switzerland. History The Stone Age Westerfeld and Büge shoreline settlements were discovered in 1861 and studied extensively 1981-83, with finds from the Pfyn culture, Pfyn, Horgen culture, Horgen and Corded Ware cultures (4000-2500 BC.) An Alamanni graveyard has also been found outside the Early Middle Ages, early medieval village. The village of Ermatingen is first mentioned in 724 as ''Erfmotingas''. It was part of the land owned by the monastery of Reichenau Island, Reichenau, and the abbot was the landlord, judge and appointed the priest for the village. The High, middle and low justice, low court in the village was administered by a monastery appointed ''Meierhof, Meier''. The position of ''Meier'' and the associated bailiwick were often used as security for a loan, for example in 1446 to the Lords of Klin ...

Lake Constance
Lake Constance (, ) refers to three bodies of water on the Rhine at the northern foot of the Alps: Upper Lake Constance (''Obersee''), Lower Lake Constance (''Untersee''), and a connecting stretch of the Rhine, called the Seerhein (). These waterbodies lie within the Lake Constance Basin () in the Alpine Foreland through which the Rhine flows. The nearby '' Mindelsee'' is not considered part of Lake Constance. The lake is situated where Germany, Switzerland, and Austria meet. Its shorelines lie in the German states of Baden-Württemberg and Bavaria; the Swiss cantons of St. Gallen, Thurgau, and Schaffhausen; and the Austrian state of Vorarlberg. The actual locations of the country borders within the lake are disputed. The Alpine Rhine forms, in its original course ( Alter Rhein), the Austro-Swiss border and flows into the lake from the south. The High Rhine flows westbound out of the lake and forms (with the exception of the Canton of Schaffhausen, Rafzerfeld and Bas ...
