Brändbach Dam
The Brändbach Dam (german: Brändbachtalsperre), whose reservoir is called the Kirnbergsee, is a small dam near Bräunlingen in Baden-Württemberg in the Black Forest. It is used to generate electricity, for flood protection and for recreation. The lake lies within the Kirnbergsee protected area, which also includes surrounding areas. The dam impounds the Brändbach stream, which is part of the Breg (river), Breg catchment. Construction The barrier is a crooked gravity dam made of concrete with rubble stone cladding. It was renovated in 2000 and was the first dam in Germany to be sealed with a plastic sealing sheet (geomembrane) of Polyvinylchloride, PVC on the reservoir side. In 1955 it had already been reinforced with concrete on the reservoir side. Power The power capacity of the hydropower station is 300 kW; it generates 0.7 GWh per year. It is operated by the town of Bräunlingen. Reservoir Since 2008, the Kirnbergsee has been assessed as of "excellent qual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schwarzwald-Baar-Kreis
Schwarzwald-Baar () is a ''Landkreis'' (district) in the south of Baden-Württemberg, Germany. Neighboring districts are (from north clockwise) Ortenaukreis, Rottweil, Tuttlingen, Constance, the Swiss canton of Schaffhausen, and the districts Waldshut, Breisgau-Hochschwarzwald and Emmendingen. History The district was created in 1973, when the districts of Donaueschingen and Villingen were merged. Geography The district got its name from the two predominant landscapes in the district. The Black Forest (''Schwarzwald''), and the ''Baar'', the foothills between the Black Forest and the Swabian Alb. Both the Danube River and the Neckar The Neckar () is a river in Germany, mainly flowing through the southwestern state of Baden-Württemberg, with a short section through Hesse. The Neckar is a major right tributary of the Rhine. Rising in the Schwarzwald-Baar-Kreis near Schwenn ... River have their origins in the Schwarzwald and Baar district.

Geomembrane
A geomembrane is very low permeability synthetic membrane liner or barrier used with any geotechnical engineering related material so as to control fluid (liquid or gas) migration in a human-made project, structure, or system. Geomembranes are made from relatively thin continuous polymeric sheets, but they can also be made from the impregnation of geotextiles with asphalt, elastomer or polymer sprays, or as multilayered bitumen geocomposites. Continuous polymer sheet geomembranes are, by far, the most common. Manufacturing The manufacturing of geomembranes begins with the production of the raw materials, which include the polymer resin, and various additives such as antioxidants, plasticizers, fillers, carbon black, and lubricants (as a processing aid). These raw materials (i.e., the "formulation") are then processed into sheets of various widths and thickness by extrusion, calendering, and/or spread coating. Geomembranes dominate the sales of geosynthetic products, at U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gravity Dams
A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by using only the weight of the material and its resistance against the foundation to oppose the horizontal pressure of water pushing against it. Gravity dams are designed so that each section of the dam is stable and independent of any other dam section. Characteristics Gravity dams generally require stiff rock foundations of high bearing strength (slightly weathered to fresh), although in rare cases, they have been built on soil foundations. The bearing strength of the foundation limits the allowable position of the resultant force, influencing the overall stability. Also, the stiff nature of the gravity dam structure is unforgiving to differential foundation settlement, which can induce cracking of the dam structure. Gravity dams provide some advantages over embankment dams, the main advantage being that they can tolerate minor over-topping flows without damage, as the concre ...

List Of Dams In Germany
These are dams and reservoirs in Germany. The 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''.

Hydropower Station
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Reservoir Side
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 of the re ...

Rubble Stone
Rubble stone is rough, uneven building stone not laid in regular courses. It may fill the core of a wall which is faced with unit masonry such as brick or ashlar. Analogously, some medieval cathedral walls are outer shells of ashlar with an inner backfill of mortarless rubble and dirt. Square Rubble Masonry Square Rubble Masonry is where face stones are dressed (squared on all joints and beds) before laying, set in Mortar (masonry), mortar and appear as the outer surface of a wall. History The sack masonry is born as an evolution of Levee, embankment covered with boards, stones or bricks. The coating was used to give the embankment greater strength and make it more difficult for the enemies to climb. The Sadd el-Kafara, Sadd el-Khafara dam, 14 meters high and built in sacking masonry in Wadi Al-Garawi near Helwan in Egypt, dates back to 2900 - 2600 BC The Greeks called the brickwork emplekton, emplecton and made use of it in particular in the construction of the defensive ...

Breg (river)
The Breg is a river, 46 kilometres long, in Baden-Württemberg, Germany, and the primary headstream of the Danube. Description The '' Breg '' is the longest and biggest headstream of the River Danube. It flows through the southeast part of the Middle Black Forest and the lowlands of the Baar region. The Breg rises at a height of , six kilometres northwest of Furtwangen. Its source, which is near St. Martin's Chapel and is also called the source of the Danube or ''Donauquelle'', is protected as a natural monument. It is located about 100 metres south-east of the Rhine / Danube watershed (the great European Watershed). Beyond that, but only about 900 metres away is the source of the Elz, which flows in the same longitudinal valley but initially in the opposite direction, to the north, and later flows into the Rhine. In its upper section, known as the ''Katzensteig'', the Breg valley is clearly a result of glaciation, with a strikingly low gradient and landscape characterize ...
