Königshütte Dam
The Königshütte Dam (german: Talsperre Königshütte) is a dam in the German state of Saxony-Anhalt in the Harz mountains. It impounds the River Bode and lies between Königshütte and Susenburg (both in the borough of Oberharz am Brocken). It is a so-called storage reservoir (''Überleitungssperre'') forming part of the Rappbode Dam system. The dam itself was built on the Bode from 1939–1943 and 1952–1956 with construction being interrupted by the war. It is an 18 metre high gravity dam, made of concrete, for the supply of drinking water and for flood protection. It also provides reserves of water during times of drought and hydro-electric power. The power station has a nominal output of 60 kW and generates 0.18 GWh per annum. The gently curving dam wall is 108 m long and has a volume of 13,500 m³. It can be overtopped along almost its entire length. In one section there is a fish-belly flap gate that can be lowered by 1.5 metres to ...

Fish-belly Flap Gate
Floodgates, also called stop gates, are adjustable gates used to control water flow in flood barriers, reservoir, river, stream, or levee systems. They may be designed to set spillway crest heights in dams, to adjust flow rates in sluices and canals, or they may be designed to stop water flow entirely as part of a levee or storm surge system. Since most of these devices operate by controlling the water surface elevation being stored or routed, they are also known as crest gates. In the case of flood bypass systems, floodgates sometimes are also used to lower the water levels in a main river or canal channels by allowing more water to flow into a flood bypass or detention basin when the main river or canal is approaching a flood stage. Types Valves Valves used in floodgate applications have a variety of design requirements and are usually located at the base of dams. Often, the most important requirement (besides regulating flow) is energy dissipation. Since water is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dams In Saxony-Anhalt
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Dams In The Harz
In the Harz mountains, there is a higher than average number of dams with their associated reservoirs. The reason is that the Harz is one of the regions with the heaviest rainfall in Germany and so its water power was utilised very early on. The first dam (on the Upper Harz Ponds) was built to drive water-powered pumps and stamp mills used in the mines. At present, the Harz reservoirs provide hydroelectricity, drinking water and flood protection particularly when the snows melt in spring. The following is a list of dams in the Harz: * Ecker Dam which impounds the waters of the Ecker * Grane Dam which impounds the waters of the Grane * Hassel Auxiliary Dam which impounds the waters of the Hassel, is part of the Rappbode Dam system * Innerste Dam which impounds the waters of the Innerste * Kelbra Dam which impounds the waters of the Helme * Königshütte Dam impounds the waters of both the Warme and Kalte Bode, and is part of the Rappbode Dam system * Mandelholz Dam (f ...

List Of Reservoirs And Dams In Germany
These are dams and reservoirs in Germany. The German language, German word ''Talsperre'' (literally: valley barrier) may mean dam, but it is often used to include the associated reservoir as well. The reservoirs are often separately given names ending in ''-see'', ''-teich'' or ''-speicher'' which are the German words for "lake", "pond" and "reservoir", but in this case all may also be translated as "reservoir". The more specific word for the actual dam is ''Staumauer'' and for the lake is ''Stausee''.

Pedestrian
A pedestrian is a person traveling on foot, whether walking or running. In modern times, the term usually refers to someone walking on a road or pavement, but this was not the case historically. The meaning of pedestrian is displayed with the morphemes ''ped-'' ('foot') and ''-ian'' ('characteristic of'). This word is derived from the Latin term ''pedester'' ('going on foot') and was first used (in English language) during the 18th century. It was originally used, and can still be used today, as an adjective meaning plain or dull. However, in this article it takes on its noun form and refers to someone who walks. The word pedestrian may have been used in middle French in the Recueil des Croniques et Anchiennes Istories de la Grant Bretaigne, à présent nommé Engleterre. In California the definition of a pedestrian has been broadened to include anyone on any human powered vehicle that is not a bicycle, as well as people operating self-propelled wheelchairs by reason of ...

Fisherman
A fisher or fisherman is someone who captures fish and other animals from a body of water, or gathers shellfish. Worldwide, there are about 38 million commercial and subsistence fishers and fish farmers. Fishers may be professional or recreational. Fishing has existed as a means of obtaining food since the Mesolithic period.Profile for the USA * inadequate preparation for emergencies * poor vessel maintenance and inadequate safety equipment * lack of awareness of or ignoring stability issues. Many fishers, while accepting that fishing is dangerous, staunchly defend their independence. Many proposed laws and additional regulation to increase safety have been defeated because fishers oppose them. Alaska's commercial fishers work in one of the world's harshest environments. Many of the hardships they endure include isolated fishing grounds, high winds, seasonal darkness, very cold water, icing, and short fishing seasons, where very long work days are the norm.

Confluence
In geography, a confluence (also: ''conflux'') occurs where two or more flowing bodies of water join to form a single channel. A confluence can occur in several configurations: at the point where a tributary joins a larger river ( main stem); or where two streams meet to become the source of a river of a new name (such as the confluence of the Monongahela and Allegheny rivers at Pittsburgh, forming the Ohio); or where two separated channels of a river (forming a river island) rejoin at the downstream end. Scientific study of confluences Confluences are studied in a variety of sciences. Hydrology studies the characteristic flow patterns of confluences and how they give rise to patterns of erosion, bars, and scour pools. The water flows and their consequences are often studied with mathematical models. Confluences are relevant to the distribution of living organisms (i.e., ecology) as well; "the general pattern ownstream of confluencesof increasing stream flow and decreasing ...

Rappbode Reservoir
The Rappbode is a right-hand, southwestern tributary of the River Bode in the Harz mountains in the German state of Saxony-Anhalt. In its lower reaches it is impounded by the Rappbode Dam, the largest dam in the Harz. The Rappbode rises east of the B 4 federal road near the ''Jägerfleck'' at the junction of the three federal states of Lower Saxony, Saxony-Anhalt and Thuringia. Its source is about southwest of Benneckenstein and southeast of Hohegeiß at an elevation of above sea level. On the opposite side of the B 4 there are numerous source streams of the river Zorge. The Rappbode flows in a mainly northeastern direction through the villages of Benneckenstein and Trautenstein, before it enters the Rappbode Auxiliary Dam and, shortly thereafter, the Rappbode Dam itself. It is united with the Bode further downstream at the Wendefurth Dam The Wendefurth Dam (german: Talsperre Wendefurth) near Wendefurth in the Harz is one of the dams downstream of the Rappbode D ...

Reservoir
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. 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 ...

Flood Control
Flood control methods are used to reduce or prevent the detrimental effects of flood waters."Flood Control", MSN Encarta, 2008 (see below: Further reading). Flood relief methods are used to reduce the effects of flood waters or high water levels. Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff. Though building hard infrastructure to prevent flooding, such as flood walls, can be effective at managing flooding, increased best practice within landscape engineering is to rely more on soft infrastructure and natural systems, such as marshes and flood plains, for handling the increase in water. For flooding on coasts, coastal management practices have to not only handle changes water flow, but also natural processes like tides. Flood control and relief is a particularly important part of climate change adaptation and climate resilience, both sea level rise and changes in the weather ...
