Canal Mauri
Canal Mauri is a canal in Peru and Chile. It transfers water from the Mauri River watershed and transfers it into the Caplina River for irrigation purposes. An earlier canal Canal Uchusuma was constructed in the early 19th century and was replaced by the Canal Mauri. This canal collects water from several tributaries of the Mauri River (notably the Uchusuma River) and diverts it through Chilean territory into the Quebrada Vilavilani, a tributary of the Caplina River; from there it is later diverted for irrigation purposes in the Tacna region. The diversion has damaged wetlands in the region and consequently the expansion project "Vilavilani II" - which would take additional water directly from the Mauri River - has engendered opposition. Name The canal is known in Peruvian sources as ''Canal Uchusuma'', but also as ''Azucarero'', ''Alto Uchusuma'' or ''Canal Uchusuma Alto''. ''Canal Uchusuma'' is also the name of a canal near Tacna, which starts on the Quebrada Vilavilani a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tacora
Tacora is a stratovolcano located in the Andes of the Arica y Parinacota Region of Chile. Near the border with Peru, it is one of the northernmost volcanoes of Chile. It is part of the Central Volcanic Zone in Chile, one of the four volcanic belts of the Andes. The Central Volcanic Zone has several of the highest volcanoes in the world. Tacora itself is a stratovolcano with a caldera and a crater. The youngest radiometric age is 50,000 years ago and it is heavily eroded by glacial activity. Volcanism in the Central Volcanic Zone results from the subduction of the Nazca Plate beneath the South America Plate. Tacora is constructed on the so-called "Arica Altiplano" and is part of a northsouth alignment of volcanoes. Tacora itself has uncertain reports of historical eruptions and there are active fumaroles. The fumarolic activity has resulted in the emplacement of substantial deposits of sulfur, which were already mentioned centuries ago. Towards the latter 19th century, sy ...

Aquifer
An aquifer is an underground layer of water-bearing, permeable rock, rock fractures, or unconsolidated materials (gravel, sand, or silt). Groundwater from aquifers can be extracted using a water well. Aquifers vary greatly in their characteristics. The study of water flow in aquifers and the characterization of aquifers is called hydrogeology. Related terms include aquitard, which is a bed of low permeability along an aquifer, and aquiclude (or ''aquifuge''), which is a solid, impermeable area underlying or overlying an aquifer, the pressure of which could create a confined aquifer. The classification of aquifers is as follows: Saturated versus unsaturated; aquifers versus aquitards; confined versus unconfined; isotropic versus anisotropic; porous, karst, or fractured; transboundary aquifer. Challenges for using groundwater include: overdrafting (extracting groundwater beyond the Dynamic equilibrium, equilibrium yield of the aquifer), groundwater-related subsidence of land, gro ...

Electric Power Development Company
The , operating under the brand name J-POWER, formerly , is an electric utility in Japan. It mainly produces electricity from coal and hydroelectric power stations. It also has a few wind farms and is currently building a nuclear plant in Ohma, Aomori prefecture, that is scheduled to begin operations in November 2014. J-Power is the sole operator of the transmission lines connecting the four main islands of Japan. History After World War II, as a part of many changes implemented, the Supreme Commander of the Allied Powers ordered the dismantling of , which at the time provided electricity to all of Japan with a semi-governmental status. This was broken up into a number of utilities, which have become Japan's modern electric utility companies. However, in the battered state of post-war Japan, there were few investors out there to put money in these new companies, and certainly not enough to allow for sufficient R&D of power sources that Japan needed to keep up with the deman ...

Soil mechanics is a branch of soil physics and applied mechanics that describes the behavior of soils. It differs from fluid mechanics and solid mechanics in the sense that soils consist of a heterogeneous mixture of fluids (usually air and water) and particles (usually clay, silt, sand, and gravel) but soil may also contain organic solids and other matter.Mitchell, J.K., and Soga, K. (2005) Fundamentals of soil behavior, Third edition, John Wiley and Sons, Inc., .Powrie, W., Spon Press, 2004, ''Soil Mechanics – 2nd ed'' A Guide to Soil Mechanics, Bolton, Malcolm, Macmillan Press, 1979. Along with rock mechanics, soil mechanics provides the theoretical basis for analysis in geotechnical engineering, a subdiscipline of civil engineering, and engineering geology, a subdiscipline of geology. Soil mechanics is used to analyze the deformations of and flow of fluids within natural and man-made structures that are supported on or made of soil, or structures that are buried in soils.L ...

Capital Cost
Capital costs are fixed, one-time expenses incurred on the purchase of land, buildings, construction, and equipment used in the production of goods or in the rendering of services. In other words, it is the total cost needed to bring a project to a commercially operable status. Whether a particular cost is capital or not depend on many factors such as accounting, tax laws, and materiality. Categories Capital costs include expenses for tangible goods such as the purchase of plants and machinery, as well as expenses for intangibles assets such as trademarks and software development. Capital costs are not limited to the initial construction of a factory or other business. Namely, the purchase of a new machine to increase production and last for years is a capital cost. Capital costs do not include labor costs (they do include construction labor). Unlike operating costs, capital costs are one-time expenses but payment may be spread out over many years in financial reports and tax r ...

General Lagos
General Lagos (indigenous name: Takura) is Chile's northernmost commune in Parinacota Province, Arica and Parinacota Region. Its capital is Visviri. The area, once part of Peru, was captured by Chilean forces in the War of the Pacific by its namesake and commander of Chilean troops in the Battle of Arica, General Pedro Lagos. Tacora volcano lies in this commune. Demographics According to the 2002 census of the National Statistics Institute, General Lagos had 1,179 inhabitants (761 men and 418 women), all listed as living in rural areas. The population grew by 16.5% (167 persons) between the 1992 and 2002 censuses. Administration As a commune, General Lagos is a third-level administrative division of Chile administered by a municipal council, headed by an alcalde who is directly elected every four years. The 2008-2012 alcalde was Gregorio Mendoza Chura. Within the electoral divisions of Chile, General Lagos is represented in the Chamber of Deputies by Nino Baltolu (UDI) and Orl ...

Treaty Of Lima (1929)
The Tacna–Arica compromise or Treaty of Lima was a series of documents that settled the territorial dispute of both Tacna and Arica provinces of Peru and Chile respectively. According to the Treaty, the Tacna-Arica Territory was divided between both countries; Tacna being awarded to Peru and with Chile retaining sovereignty over Arica. Chile also agreed to pay up to 6 million dollars in compensation to Peru. The Treaty was signed on June 3, 1929, in the city of Lima by then Peruvian Representative Pedro José Rada y Gamio and Chilean Representative Emiliano Figueroa Larrain. Background The controversy was a direct aftermath of the War of the Pacific, a confrontation that involved Chile against Peru and Bolivia. Chile won the war and conquered the Peruvian territories of Tarapacá, Tacna and Arica. The defeated Peruvian government was forced to sign the Treaty of Ancón in 1883. According to this treaty, Tarapacá was annexed to Chile, and a plebiscite was meant to take plac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Irrigated Agriculture
Irrigation (also referred to as watering) is the practice of applying controlled amounts of water to land to help grow Crop, crops, Landscape plant, landscape plants, and Lawn, 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 revegetation, 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 irri ...
