The geography of Italy includes the description of all the physical geographical elements of Italy. Italy, whose territory largely coincides with the homonymous geographical region, is located in southern Europe and comprises the long, boot-shaped Italian Peninsula crossed by the Apennines, the southern side of Alps, the large plain of the Po Valley and some islands including Sicily and Sardinia. Italy is part of the Northern Hemisphere. Two of the Pelagie Islands are located on the African continent.
Sardinia is the second-largest island in the Mediterranean Sea, after Sicily, and one of the 20 regions of Italy. It is located west of the Italian Peninsula, north of Tunisia and immediately south of the French island of Corsica.
The nuraghe, or also nurhag in English, is the main type of ancient megalithic edifice found in Sardinia, developed during the Nuragic Age between 1900 and 730 B.C. Today it has come to be the symbol of Sardinia and its distinctive culture known as the Nuragic civilization. More than 7,000 nuraghes have been found, though archeologists believe that originally there were more than 10,000.
Lake Nasser is a vast reservoir in southern Egypt and northern Sudan. It is one of the largest man-made lakes in the world. Before construction, Sudan was against the building of Lake Nasser, because it would encroach on land in the northern part of the country, where many Nubian people lived who would have to be resettled. In the end Sudan's land near the area of Lake Nasser was mostly flooded by the lake.
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower. 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. However, when constructed in lowland rainforest areas, where part of the forest is inundated, substantial amounts of greenhouse gases may be emitted.
The Sardinian pika is an extinct species of pika that was endemic to the islands of Sardinia, Corsica and neighbouring Mediterranean islands until its extinction likely in Roman times. Unlike living pikas, which all belong to the genus Ochotona, the Sardinian pika was the last surviving member of the genus Prolagus, a genus of pika once widespread throughout western Eurasia and North Africa during the Miocene and Pliocene epochs.
Lake Benmore is New Zealand's largest artificial lake. Located in the South Island of New Zealand and part of the Waitaki River, it was created in the 1960s by construction of Benmore Dam.
A spillway is a structure used to provide the controlled release of water downstream from a dam or levee, typically into the riverbed of the dammed river itself. In the United Kingdom, they may be known as overflow channels. Spillways ensure that water does not damage parts of the structure not designed to convey water.
The province of Sassari is a province in the autonomous island region of Sardinia in Italy. Its capital is the city of Sassari. As of 2017, the province had a population of 493,357 inhabitants.
Lake Oroville is a reservoir formed by the Oroville Dam impounding the Feather River, located in Butte County, northern California. The lake is situated 5 miles (8 km) northeast of the city of Oroville, within the Lake Oroville State Recreation Area, in the western foothills of the Sierra Nevada. Known as the second-largest reservoir in California, Lake Oroville is treated as a keystone facility within the California State Water Project by storing water, providing flood control, recreation, freshwater releases assist in controlling the salinity intrusion into the Sacramento-San Joaquin Delta and protecting fish and wildlife.
The San Luis Reservoir is an artificial lake on San Luis Creek in the eastern slopes of the Diablo Range of Merced County, California, approximately 12 mi (19 km) west of Los Banos on State Route 152, which crosses Pacheco Pass and runs along its north shore. It is the fifth largest reservoir in California. The reservoir stores water taken from the San Joaquin-Sacramento River Delta. Water is pumped uphill into the reservoir from the O'Neill Forebay which is fed by the California Aqueduct and is released back into the forebay to continue downstream along the aqueduct as needed for farm irrigation and other uses. Depending on water levels, the reservoir is approximately nine miles (14 km) long from north to south at its longest point, and five miles (8 km) wide. At the eastern end of the reservoir is the San Luis Dam, the fourth largest embankment dam in the United States, which allows for a total capacity of 2,041,000 acre-feet (2,518,000 dam3). Pacheco State Park lies along its western shores.
Orroli, meaning "downy oak" is, a comune (municipality) in the Province of South Sardinia in the Italian region of Sardinia, located about 67.4 kilometres (41.9 mi) north of Cagliari. As of 31 December 2010, it had a population of 2,430 and an area of 75.6 square kilometres (29.2 sq mi). Orroli territory hosts one of the most important nuraghi of Sardinia called Nuraghe Arrubiu, the only intact example of a five-tower nuraghe, one of the dam in the Flumendosa river and the dam of the Mulargia, which gave name to the artificial lake. Within the village there are many hostels and bed and breakfasts organized around old lifestyles and ancient traditions.
Campidano is a plain located in South-Western Sardinia (Italy), covering approximately 100 kilometres between Cagliari and Oristano.
Lake Qaraoun is an artificial lake or reservoir located in the southern region of the Beqaa Valley, Lebanon. It was created near Qaraoun village in 1959 by building a 61 m-high (200 ft) concrete-faced rockfill dam in the middle reaches of the Litani River. The reservoir has been used for hydropower generation, domestic water supply, and for irrigation of 27,500 ha.
Anderson Lake, also known as Anderson Reservoir, is an artificial lake in Morgan Hill, located in southern Santa Clara County, California. The reservoir is formed by the damming of Coyote Creek just below its confluence with Las Animas Creek. A 4,275-acre (1,730 ha) county park surrounds the reservoir and provides limited fishing, picnicking, and hiking activities. Although swimming is prohibited, boating, water-skiing, and jet-skiing are permitted in the reservoir.
Lake Peruća or Peruča is the second largest artificial lake in Croatia, after Lake Dubrava. It is located in the Split-Dalmatia County.
Lake Coghinas is an artificial lake, in northern Sardinia, Italy, located in the province of Sassari. With a surface of 17.8 km² and a capacity of 254 million cubic metres of water, it is the second largest lake in the region and one of the major reservoirs in Italy.
The Sardinians, or Sards, are a Romance language-speaking ethnic group native to Sardinia, from which the western Mediterranean island and autonomous region of Italy derives its name.
Codole Reservoir is a reservoir in the Haute-Corse department of France, on the island of Corsica. It supplies water for drinking and irrigation. The reservoir and its immediate surroundings are important as a biotope that offers habitat for many species of birds, reptiles and amphibians
