Limón Dam
The Limón Dam, part of the Olmos Transandino Project, is an under construction multi-purpose concrete-face rock-fill embankment dam on the Huancabamba River in northwestern Peru, located to the south of Guabal. When completed, the project will help produce of electricity per year and transfer water from the Cajamarca region west to Lambayeque, near Olmos for the reclamation and irrigation of of farmland. The greatest feature and engineering challenge of the project was digging the trans-Andean tunnel as it connects the Atlantic side of the Andes (Amazon basin) with the Pacific side. The Olmos Irrigation Project is the largest of seven irrigation projects in Peru. History and construction The idea to divert the Huancabamba River to the fertile but arid lands of Olmos was first envisioned in 1924. The hydroelectric component was added in the 1940s and 1950s. Preliminary feasibility studies were conducted in the 1960s by Italconsult, in 1979-1982 soviet engineers from Hyd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Huancabamba River
The Huancabamba River ("Stony Plain" in the Quechua language) in the Pasco Region of Peru has its origin in the confluence of several small rivers near the town of Oxapampa: the Chontabamba, the Llamaquizú, and the Esperanza rivers. From an elevation of at Oxapampa, the Huancabamba River runs northward for approximately by road paralleling the river to the village of Pozuzo. The Huancabamba is joined by the Santa Cruz River north of Pozuzo at an elevation of and thereafter is called the Pozuzo River. In its lower course the Pozuzó is called the Pachitea River which joins the Ucayali River, a major component in the Amazon River drainage basin. The Huancabamba runs in steep canyons for part of its course and with mountains on either side rising to more than in elevation. A few kilometres of the river above Pozuzo is within the Yanachaga–Chemillén National Park. The river is located in the ecological zone of the Peruvian Yungas, or Ceja de Selva ("eyebrow of the j ...

Dams In Peru
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, tap water, human consumption, Industrial water, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as Dike (construction), dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam (Jordan), Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam.

Water Tunnels
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 covers ab ...

Tunnels In Peru
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers saf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reservoirs In Peru
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 ...

Buildings And Structures In Cajamarca Region
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much art ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Strip The City
''Strip the City'' is a documentary science television series that aired on the Science Channel in 2012 and 2014. It explores the construction of major cities and the geology lying beneath them, with an emphasis on computer-generated imagery to "strip" away layers of structures and the rock of geological features to reveal their interiors. Content ''Strip the City'' uses computer-generated imagery (CGI) to "strip" major cities layer-by-layer of their steel, concrete, buildings, roads, rivers. and bedrock to reveal the technology and infrastructure that allowed their creation and keeps them functioning. CGI also peels back the layers of buildings to show they were constructed, strips away oceans to reveal sunken cities, and cuts into rock to display the inner workings of volcanoes, subterranean rivers, underground volcanoes and cliffs, fault lines, and ancient catacombs and describe their impact on life in the cities above them. A later Science Channel series, ''Strip the Cosmos'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
