Reservoir
A reservoir (; ) is an enlarged lake behind a dam, usually built to water storage, store fresh water, often doubling for hydroelectric power generation. Reservoirs are created by controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an Bay, embayment within it, excavating, or building any number of retaining walls or levees to enclose any area to store water. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley and rely on the natural topography to provide most of the basin of the reservoir. These reservoirs can either be ''on-stream reservoirs'', which are located on the original streambed of the downstream river and are filled by stream, creeks, rivers or rainwater that surface runoff, runs off the surrounding forested catchments, or ''off-stream reservoirs'', which receive water diversion, diverted water from a nearby stream or aqueduct (water supply), aq ...

Spöl
The Spöl or Aqua Granda is an Italian and Swiss river and is a right tributary of the Inn. The source of the river is near Corno di Campo in the Province of Sondrio in Italy. It flows northeast past Livigno and into Lago di Livigno. It exits the lake at the Italian/Swiss border and flows northwest through Parc Naziunal Svizzer before emptying into the Inn near Zernez. Despite rising in Italy, the river is a tributary of the Inn, and the Danube, rather than of the Po. In other words, its valley is on the northern side of the Alpine watershed. In this area geographical and political boundaries do not coincide. Due to an international treaty, an artificial lake, Lago di Livigno, was created by Engadiner Kraftwerke in the 1960s, with a dam on the border. Despite indemnisation, not all inhabitants were willing to leave this part of the valley. The reservoir has a capacity of . Its minimum and maximum water levels above sea level are at and respectively. Since its constr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arch Dam
An arch dam is a concrete dam that is curved upstream in plan. The arch dam is designed so that the force of the water against it, known as hydrostatic pressure, presses against the arch, causing the arch to straighten slightly and strengthening the structure as it pushes into its foundation or abutments. An arch dam is most suitable for narrow canyons or gorges with steep walls of stable rock to support the structure and stresses. Since they are thinner than any other dam type, they require much less construction material, making them economical and practical in remote areas. Classification In general, arch dams are classified based on the ratio of the base thickness to the structural height (b/h) as: * Thin, for b/h less than 0.2, * Medium-thick, for b/h between 0.2 and 0.3, and * Thick, for b/h ratio over 0.3. Arch dams classified with respect to their structural height are: * Low dams up to , * Medium high dams between , * High dams over . History The development ...

List Of Lakes Of Switzerland
This article contains a sortable table listing all major lakes of Switzerland. The table includes all still water bodies located either entirely or partly in Switzerland, both natural and artificial, that have a surface area of at least , regardless of water volume, maximum depth or other metric. These lakes are ranked by area, the table including also the elevation above sea level and maximum depth. They are either natural (type N), natural but used as reservoirs (NR) or fully artificial (A). Along with the mountains, lakes constitute a major natural feature of Switzerland, with over of shores within the country.Approximately (see coastline paradox) counting only the 17 lakes over (length retrieved from the Google Earth geographical information program). Lakes, large and small, can be found in almost all cantons and provide an important source of water, leisure opportunities, as well as suitable habitat for fish-eating birds.

List Of Mountain Lakes Of Switzerland
This is a list of high-altitude lakes of Switzerland. It includes all significant lakes located either entirely or partly in Switzerland, both natural and artificial, with an area of at least 4 ha (9.9 acres) and a location at over above sea level. This altitude approximately corresponds to the transition between the foothill zone and the montane zone in both the Alps and the Jura Mountains, the two mountainous areas of Switzerland. Lakes can be found up to elevations of almost , the climatic snow line in the Alps.

Lakes Of Graubünden
A lake is often a naturally occurring, relatively large and fixed body of water on or near the Earth's surface. It is localized in a basin or interconnected basins surrounded by dry land. Lakes lie completely on land and are separate from the ocean, although they may be connected with the ocean by rivers. Lakes, as with other bodies of water, are part of the water cycle, the processes by which water moves around the Earth. Most lakes are fresh water and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume of water. Lakes are typically larger and deeper than ponds, which are also water-filled basins on land, although there are no official definitions or scientific criteria distinguishing the two. Lakes are also distinct from lagoons, which are generally shallow tidal pools dammed by sandbars or other material at coastal regions of oceans or large la ...

Arch Dams
An arch is a curved vertical structure spanning an open space underneath it. Arches may support the load above them, or they may perform a purely decorative role. As a decorative element, the arch dates back to the 4th millennium BC, but structural load-bearing arches became popular only after their adoption by the Ancient Romans in the 4th century BC. Arch-like structures can be horizontal, like an arch dam that withstands the horizontal hydrostatic pressure load. Arches are usually used as supports for many types of vaults, with the barrel vault in particular being a continuous arch. Extensive use of arches and vaults characterizes an arcuated construction, as opposed to the trabeated system, where, like in the architectures of ancient Greece, China, and Japan (as well as the modern steel-framed technique), posts and beams dominate. Arches had several advantages over the lintel, especially in the masonry construction: with the same amount of material it can have larger ...
