Black Pockau
The Black Pockau (german: Schwarze Pockau or ''Schwarzwasser'', cz, Černá) is a river of Saxony, Germany, in the Ore Mountains. It is a left tributary of the Flöha. This virtually unspoilt wild stream with a length of is known for the picturesque gorge in its middle reaches. Its murky waters flowing from bogs in the hills give the river a dark colour. The name Pockau, which was recorded in similar form in 1292, probably comes from the Czech and means "opposed", i.e. a stream flowing from Bohemia towards the north. Course The Black Pockau rises 890 metres above sea level (NHN) in a raised bog northeast of the Jelení hora in the Bohemian Ore Mountains. The (German: ''Assigbach''), which flows into the Czech Republic, also has its source here. After , the stream reaches the German-Czech border at the old road between Přísečnice (''Preßnitz'') and Kalek (''Kallich'') and flows through the Satzung municipal pond (''Satzunger Gemeindeteich''). From here on, it for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Weir
A weir or low head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the river level. Weirs are also used to control the flow of water for outlets of lakes, ponds, and reservoirs. There are many weir designs, but commonly water flows freely over the top of the weir crest before cascading down to a lower level. Etymology There is no single definition as to what constitutes a weir and one English dictionary simply defines a weir as a small dam, likely originating from Middle English ''were'', Old English ''wer'', derivative of root of ''werian,'' meaning "to defend, dam". Function Commonly, weirs are used to prevent flooding, measure water discharge, and help render rivers more navigable by boat. In some locations, the terms dam and weir are synonymous, but normally there is a clear distinction made between the structures. Usually, a dam is designed specifically to impound water behind ...

Water Gauge
Water (chemical formula ) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food, energy or organic micronutrients. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is also the name of the liquid state of H2O at standard temperature and pressure. A number of natural states of water exist. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. Water co ...

Lauterstein Castle (Marienberg)
Lauterstein Castle, in German Burg Lauterstein, also called ''Burgruine Niederlauterstein'', is a medieval castle in Niederlauterstein, town of Marienberg, Erzgebirgskreis, Saxony. It has been a ruin since the Thirty Years' War. Geography Lauterstein castle is situated on a gneiss rock at the eastern end of Niederlauterstein village, above the left bank of Schwarze Pockau river, approximately 2 km north-west of Zöblitz and 4.5 km north-east of Marienberg. History Archeological investigations in the 1970s have shown that the castle was built in the second half of the 12th century. It was first mentioned in writing in 1304 when a document named a ''Johannis in Lutirstein'' of the ministerial family of Erdmannsdorf in the castle. The castle was mainly built from stone, hence probably the name ending in ''-stein''. Its purpose was the protection of a medieval trade route between Leipzig and Prague across the Ore Mountains. The family of Schellenberg became lords o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Niederlauterstein
Niederlauterstein is a village in Saxony which has been incorporated into the town of Marienberg in the district Erzgebirgskreis since 1996. Geography Niederlauterstein is a dispersed settlement (''Streusiedlung''), situated about north-east of Marienberg in the Ore Mountains. It extends from the left bank of Schwarze Pockau river for about westward on a steep slope. The ruined Lauterstein Castle which formed the origin of the settlement is situated on a rock spur above the river, at the eastern end of the village.

Slip-off Slope
A slip-off slope is a depositional landform that occurs on the inside convex bank of a meandering river. The term can refer to two different features: one in a freely meandering river with a floodplain and the other in an entrenched river. Freely meandering rivers In a freely meandering river, a ''slip-off slope'' is characterized by a gentle slope composed of sand and pebbles on the inside convex bank of a meander loop, across the channel from a cut bank or river-cut cliff.Scheffers, A.M., May, S.M. and Kelletat, D.H., 2015. ''Forms by Flowing Water (Fluvial Features).'' In ''Landforms of the World with Google Earth.'' (pp. 183-244). Springer, Amsterdam, Netherlands. 391 pp. As water in a meandering river travels around a bend, it moves in a secondary corkscrew-like flow as it travels downstream, in a pattern called helicoidal flow. This phenomenon causes increased water velocity in the outside bend of the meander, driving lateral bank erosion. It is also responsible for slo ...

Kunstgraben
A ''Kunstgraben'' is a type of man-made water channel that was once used by mines to drive the water wheels needed for power, mine drainage and a host of other purposes. The term is German (plural: ''Kunstgräben''). Similar ditches supplying water mills in England are called leats. Background Until the invention of the steam engine, water power was the main source of energy utilised by the various mechanical engines employed in the mining industry, such as water wheels, reversible water wheels, water-column engines or water turbines. To enable mine workings to be driven ever deeper, more and more power was needed. The water available in the vicinity of the pits was insufficient for that purpose and springs frequently dried up as a result of be diverted for use in the mines. As a result, the water needed for the mine workings sometimes had to be transported over long distances. Usage The aim was to have the greatest possible height difference at the site of the water pow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydropower
Hydropower (from el, ὕδωρ, "water"), also known as water power, is the use of falling or fast-running water to Electricity generation, produce electricity or to power machines. This is achieved by energy transformation, converting the Potential energy, 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 Hydroelectricity, 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 in Earth's atmosphere, carbon dioxide or other Air pollution, 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. Int ...

Abandoned Village
An abandoned village is a village that has, for some reason, been deserted. In many countries, and throughout history, thousands of villages have been deserted for a variety of causes. Abandonment of villages is often related to epidemic, famine, war, climate change, economic depressions, environmental destruction, or deliberate clearances. Armenia and Azerbaijan Hundreds of villages in Nagorno-Karabakh were deserted following the First Nagorno-Karabakh War. Between 1988 and 1993, 400,000 ethnic Azeris, and Kurds fled the area and nearly 200 villages in Armenia itself populated by Azeris and Kurds were abandoned by 1991. Likewise nearly 300,000 Armenians fled from Azerbaijan between 1988 and 1993, including 50 villages populated by Armenians in Northern Nagorno Karabakh that were abandoned. Some of the Armenian settlements and churches outside Armenia and the Nagorno-Karabakh Republic have either been destroyed or damaged including those in Nakhichevan. Australia In Austr ...
