Lago Di Ledro
Lago di Ledro is a lake in Trentino, northern Italy. The lake is at an elevation of , and its surface area is . Lake Ledro is reputed to be one of the cleanest lakes in Trentino, and during the summer it reaches a temperature of , attracting tourists with its four beaches. In 2009 and 2011 the lake suffered from algal blooms, caused by Planktothrix. History Lake Ledro originates from the deposition of a morainal bank during the fourth glacial era. Since 1929, the lake level has been regulated to suit the energy requirements of the hydroelectric power station of Riva del Garda, which uses the water of the lake to produce electricity on a pumped-storage basis. The Lake's water sources are mainly underneath the lake. There are also tributaries (Massangla ''openstreetmap.org'', accessed 4 ...

Trentino
Trentino ( lld, Trentin), officially the Autonomous Province of Trento, is an autonomous province of Italy, in the country's far north. The Trentino and South Tyrol constitute the region of Trentino-Alto Adige/Südtirol, an autonomous region under the constitution. The province is composed of 166 ''comuni'' (municipalities). Its capital is the city of Trento (Trent). The province covers an area of more than , with a total population of 541,098 in 2019. Trentino is renowned for its mountains, such as the Dolomites, which are part of the Alps. Etymology The province is generally known as "Trentino". The name derives from Trento, the capital city of the province. Originally, the term was used by the local population only to refer to the city and its immediate surroundings. Under former Austrian rule, which began in the 19th century (previously, Trentino was governed by the local bishop), the common German name for the region was ''Welschtirol'' () or ''Welschsüdtirol'' (‘It ...

Lake
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Italy
Italy ( it, Italia ), officially the Italian Republic, ) or the Republic of Italy, is a country in Southern Europe. It is located in the middle of the Mediterranean Sea, and its territory largely coincides with the homonymous geographical region. Italy is also considered part of Western Europe, and shares land borders with France, Switzerland, Austria, Slovenia and the enclaved microstates of Vatican City and San Marino. It has a territorial exclave in Switzerland, Campione. Italy covers an area of , with a population of over 60 million. It is the third-most populous member state of the European Union, the sixth-most populous country in Europe, and the tenth-largest country in the continent by land area. Italy's capital and largest city is Rome. Italy was the native place of many civilizations such as the Italic peoples and the Etruscans, while due to its central geographic location in Southern Europe and the Mediterranean, the country has also historically been home ...

Algal Blooms
An algal bloom or algae bloom is a rapid increase or accumulation in the population of algae in freshwater or marine water systems. It is often recognized by the discoloration in the water from the algae's pigments. The term ''algae'' encompasses many types of aquatic photosynthetic organisms, both macroscopic multicellular organisms like seaweed and microscopic unicellular organisms like cyanobacteria. ''Algal bloom'' commonly refers to the rapid growth of microscopic unicellular algae, not macroscopic algae. An example of a macroscopic algal bloom is a kelp forest. Algal blooms are the result of a nutrient, like nitrogen or phosphorus from various sources (for example fertilizer runoff or other forms of nutrient pollution), entering the aquatic system and causing excessive growth of algae. An algal bloom affects the whole ecosystem. Consequences range from the benign feeding of higher trophic levels to more harmful effects like blocking sunlight from reaching other or ...

Planktothrix
''Planktothrix'' is a diverse genus of filamentous cyanobacteria observed to amass in algal blooms in water ecosystems across the globe. Like all Oscillatoriales, ''Planktothrix'' species have no heterocysts and no akinetes. Planktothrix are unique because they have trichomes and contain gas vacuoles unlike typical planktonic organisms. Previously, some species of the taxon were grouped within the genus ''Oscillatoria,'' but recent work has defined Planktothrix as its own genus. A tremendous body of work on ''Planktothrix'' ecology and physiology has been done by Anthony E. Walsby, and the 55.6 kb microcystin synthetase gene which gives these organisms the ability to synthesize toxins has been sequenced. ''P. agardhii'' is an example of a type species of the genus. ''P. agardhii'' and ''P. rubescens'' are commonly observed in lakes of the Northern Hemisphere where they are known producers of potent hepatotoxins called microcystins. Habitats and niches Both ''P. agardhii'' and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moraine
A moraine is any accumulation of unconsolidated debris (regolith and rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders (in which case it is often referred to as boulder clay) down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines were formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines (till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet). Etymology The word ''moraine'' is borrowed from French , which in turn is derived from the Savoyard Italian ("mound of earth"). ''Morena'' in this case was derived from Proven ...

Hydroelectric
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.

Ponale Hydroelectric Power Plant
Ponale Hydroelectric Power Plant ( it, Centrale idroelettrica del Ponale) is a pumped storage plant, located in city of Riva del Garda in the Italian province of Trentino, on River Ponale between Lake Ledro and Lake Garda. Its output capability is 76MW. The station was built in 1928-1929 and, following rework of the pipes, underwent overhaul in 1998. From Lake Ledro, the water is ducted several kilometers to penstocks at a point (close to the Chiesa di Santa Barbara) almost directly above the power station buildings and machinery at Riva del Garda; from here it falls on a gradient approaching 3:1 to the turbines. The station is known by the world record in high-rise concrete pumping during the reconstruction in 1994. The achieved record was 532m.; it was beaten only during construction of Burj Khalifa The Burj Khalifa (; ar, برج خليفة, , Khalifa Tower), known as the Burj Dubai prior to its inauguration in 2010, is a skyscraper in Dubai, United Arab Emirates. ...

Riva Del Garda
Riva del Garda (''Rìva'' in local dialect) is a town and ''comune'' in the northern Italian province of Trento of the Trentino Alto Adige region. It is also known simply as ''Riva'' and is located at the northern tip of Lake Garda. History Riva del Garda belonged to the Republic of Venice, the Bishopric of Trent, the Napoleonic Kingdom of Italy and later (1815–1918) to the Austro-Hungarian Empire (when it was known as ). During the Third Italian War of Independence, Riva del Garda was an important supply base for the Austrian navy and was the only town on the lake captured by Italian forces. In 1918, after the end of World War I, Riva del Garda, with the rest of the Trentino, became part of the Kingdom of Italy. Riva was the terminus for the long Mori–Arco–Riva railway line, opened in 1891. However, the railway line closed in 1936 and the railway terminus has been converted into a restaurant. Austrian dictator Kurt Schuschnigg was born in the town in 1897 and was of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pumped-storage Hydroelectricity
Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the pumps. During periods of high electrical demand, the stored water is released through turbines to produce electric power. Although the losses of the pumping process make the plant a net consumer of energy overall, the system increases revenue by selling more electricity during periods of peak demand, when electricity prices are highest. If the upper lake collects significant rainfall or is fed by a river then the plant may be a net energy producer in the manner of a traditional hydroelectric plant. Pumped-storage hydroelectricity allows energy from intermittent sources (such as solar, wind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
