Argon Pedion
Argon Pedion ( gr, Ἀργὸν Πεδίον, 3=untilled plain) is the geological name of a "closed karst basin" in the Arcadian highlands in the Peloponnese peninsula of southern Greece. The first known appearance of this name was in a publication by the ancient geographer Pausanias (110–180 AD). He called it untilled plain, because the grassland and acres may be flooded beyond the time when annual vegetation starts. When the winter rains were very heavy, floods can even turn the plain into a temporary lake. Intensive karst formation (drainage in underground waterways of limestone layers) prevents the formation of a permanent lake. In rare cases, even today, modern technologies can not prevent flooding. Geography Environment The prefecture Arcadia (Νομός Αρκαδίας) is almost entirely rural and mountainous (Arcadian Plateau). The villages are scattered all over the land; there are only very few cities, even the largest city Tripoli, Greece, with ca. 30000 in ...

Karst
Karst is a topography formed from the dissolution of soluble rocks such as limestone, Dolomite (rock), dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German language, German in the late 19th century, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mediterranean Sea
The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Western and Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant. The Sea has played a central role in the history of Western civilization. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide.

Laconia
Laconia or Lakonia ( el, Λακωνία, , ) is a historical and administrative region of Greece located on the southeastern part of the Peloponnese peninsula. Its administrative capital is Sparta. The word '' laconic''—to speak in a blunt, concise way—is derived from the name of this region, a reference to the ancient Spartans who were renowned for their verbal austerity and blunt, often pithy remarks. Geography Laconia is bordered by Messenia to the west and Arcadia to the north and is surrounded by the Myrtoan Sea to the east and by the Laconian Gulf and the Mediterranean Sea to the south. It encompasses Cape Malea and Cape Tainaron and a large part of the Mani Peninsula. The Mani Peninsula is in the west region of Laconia. The islands of Kythira and Antikythera lie to the south, but they administratively belong to the Attica regional unit of islands. The island, Elafonisos, situated between the Laconian mainland and Kythira, is part of Laconia. The Eurotas is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Messenia
Messenia or Messinia ( ; el, Μεσσηνία ) is a regional unit (''perifereiaki enotita'') in the southwestern part of the Peloponnese region, in Greece. Until the implementation of the Kallikratis plan on 1 January 2011, Messenia was a prefecture (''nomos'') covering the same territory. The capital and largest city of Messenia is Kalamata. Geography Physical Messenia borders on Elis to the north, Arcadia to the northeast, and Laconia to the southeast. The Ionian Sea lies to the west, and the Gulf of Messinia to the south. The most important mountain ranges are the Taygetus in the east, the Kyparissia mountains in the northwest and the Lykodimo in the southwest. The main rivers are the Neda in the north and the Pamisos in central Messenia. Off the south coast of the southwesternmost point of Messenia lie the Messinian Oinousses islands. The largest of these are Sapientza, Schiza and Venetiko. The small island Sphacteria closes off the bay of Pylos. All these ...

Megalopoli
Megalopoli ( el, Μεγαλόπολη) is a town in the southwestern part of the regional unit of Arcadia, southern Greece. It is located in the same site as ancient Megalopolis ( grc, Μεγαλόπολις, literally ''large/great city''). When it was founded in 371 BC, it was the first large urbanization in rustic Arcadia. Its theater had a capacity of 20,000 visitors, making it one of the largest ancient Greek theaters. Today Megalopoli has several schools, shops, churches, hotels and other services. The population of Megalopoli in 2011 was 5,779 residents. Geography Megalopoli is situated in a wide valley, surrounded by mountains: the Taygetus to the south, the Mainalo to the north, the Tsemperou to the southeast and the Lykaion to the west. Its elevation is 430 m above sea level. The river Alfeios flows through this valley, coming from the east and flowing to the north, passing south and west of the town. Its tributary Elissonas passes north of the town. The large lig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corinth
Corinth ( ; el, Κόρινθος, Kórinthos, ) is the successor to an ancient city, and is a former municipality in Corinthia, Peloponnese (region), Peloponnese, which is located in south-central Greece. Since the 2011 local government reform, it has been part of the Corinth (municipality), municipality of Corinth, of which it is the seat and a municipal unit. It is the capital of Corinthia. It was founded as Nea Korinthos (), or New Corinth, in 1858 after an earthquake destroyed the existing settlement of Corinth, which had developed in and around the site of ancient Corinth. Geography Located about west of Athens, Corinth is surrounded by the coastal townlets of (clockwise) Lechaio, Isthmia, Corinthia, Isthmia, Kechries, and the inland townlets of Examilia and the archaeological site and village of ancient Corinth. Natural features around the city include the narrow coastal plain of Vocha (plain of), Vocha, the Gulf of Corinth, Corinthian Gulf, the Isthmus of Corinth ...

Corinthian Gulf
The Gulf of Corinth or the Corinthian Gulf ( el, Κορινθιακός Kόλπος, ''Korinthiakόs Kόlpos'', ) is a deep inlet of the Ionian Sea, separating the Peloponnese from western mainland Greece. It is bounded in the east by the Isthmus of Corinth which includes the shipping-designed Corinth Canal and in the west by the Strait of Rion which widens into the shorter Gulf of Patras (part of the Ionian Sea) and of which the narrowest point is crossed since 2004 by the Rio–Antirrio bridge. The gulf is bordered by the large administrative divisions (regional units): Aetolia-Acarnania and Phocis in the north, Boeotia in the northeast, Attica in the east, Corinthia in the southeast and south and Achaea in the southwest. The gulf is in tectonic movement comparable to movement in parts of Iceland and Turkey, growing by per year. In the Middle Ages, the gulf was known as the Gulf of Lepanto (the Italian form of Naupactus). Shipping routes between the Greek commer ...

Hydroelectric Power 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.

Irrigation
Irrigation (also referred to as watering) is the practice of applying controlled amounts of water to land to help grow crops, landscape plants, and lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world. Irrigation helps to grow crops, maintain landscapes, and revegetate disturbed soils in dry areas and during times of below-average rainfall. In addition to these uses, irrigation is also employed to protect crops from frost, suppress weed growth in grain fields, and prevent soil consolidation. It is also used to cool livestock, reduce dust, dispose of sewage, and support mining operations. Drainage, which involves the removal of surface and sub-surface water from a given location, is often studied in conjunction with irrigation. There are several methods of irrigation that differ in how water is supplied to plants. Surface irrigation, also known as gravity irrigation, is the oldest form of irr ...

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 ...

Biodiversity
Biodiversity or biological diversity is the variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic (''genetic variability''), species (''species diversity''), and ecosystem (''ecosystem diversity'') level. Biodiversity is not distributed evenly on Earth; it is usually greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than 10% of earth's surface and contain about 90% of the world's species. Marine biodiversity is usually higher along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future as a primary result of deforestation. It encompasses the evolutionary, ecological, and cultural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
