Puquios
Puquios (from Quechua ''pukyu'' meaning source, spring, or water well) are ancient systems of subterranean aqueducts which allow water to be transported over long distances in hot dry climates without loss of much of the water to evaporation. Puquios are found in the coastal deserts of southern Peru, especially in the Nazca region, and northern Chile. Forty-three puquios in the Nazca region were still in use in the early 21st century and relied upon to bring fresh water for irrigation and domestic use into desert settlements. The origin and dating of the Nazca puquios is disputed, although some archaeologists have estimated that their construction began about 500 CE by indigenous people of the Nazca culture. The technology of the puquios is similar to that of the Qanats of Iran and other desert areas of Asia and Europe, including Spain. A few puquios in northern Chile and in other parts of Peru were probably constructed at the initiative of the Spanish after the conquest ...

Nazca Culture
The Nazca culture (also Nasca) was the archaeological culture that flourished from beside the arid, southern coast of Peru in the river valleys of the Rio Grande de Nazca drainage and the Ica Valley.''The Nasca'' by Helaine Silverman and Donald A. Proulx. Blackwell Publishers. Malden. 2002. Strongly influenced by the preceding Paracas culture, which was known for extremely complex textiles, the Nazca produced an array of crafts and technologies such as ceramics, textiles, and geoglyphs. They are known for two extensive construction projects that would have required the coordination of large groups of laborers: the Nazca Lines, immense designs in the desert whose purpose is unknown, and puquios, underground aqueducts for providing water for irrigation and domestic purposes in the arid environment. Several dozen still function today. The Nazca Province in the Ica Region was named for this people. History Time frame Nazca society developed during the Early Intermediate Period ...

Qanat Cross Section
A qanat or kārīz is a system for transporting water from an aquifer or water well to the surface, through an underground aqueduct; the system originated approximately 3,000 BC in what is now Iran. The function is essentially the same across North Africa and the Middle East but the system operates under a variety of regional names: ''qanat'' or kārīz in Iran, ''foggara'' in Algeria, ''khettara'' in Morocco, ''falaj'' in Oman, ''karez'' in Afghanistan, ''auyoun'' in Saudi Arabia, et al. The largest extant and functional qanat systems are located in Iran, Afghanistan, Oman, the oases of Turfan region of China, Algeria, and Pakistan. This is a system of water supply that allows water to be transported over long distances in hot dry climates without loss of much of the water to evaporation. The system has the advantage of being resistant to natural disasters such as earthquakes and floods, and to deliberate destruction in war. Furthermore, it is almost insensitive to the level ...

Atacama Desert
The Atacama Desert ( es, Desierto de Atacama) is a desert plateau in South America covering a 1,600 km (990 mi) strip of land on the Pacific coast, west of the Andes Mountains. The Atacama Desert is the driest nonpolar desert in the world, and the second driest overall, just behind some very specific spots within the McMurdo Dry Valleys as well as the only hot true desert to receive less precipitation than the polar deserts, and the largest fog desert in the world. Both regions have been used as experimentation sites on Earth for Mars expedition simulations. The Atacama Desert occupies , or if the barren lower slopes of the Andes are included. Most of the desert is composed of stony terrain, salt lakes (''salares''), sand, and felsic lava that flows towards the Andes. The desert owes its extreme aridity to a constant temperature inversion due to the cool north-flowing Humboldt ocean current and to the presence of the strong Pacific anticyclone. The most arid re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nazca
Nazca (; sometimes spelled Nasca; qu, Naska) is a city and system of valleys on the southern coast of Peru. It is also the name of the largest existing town in the Nazca Province. The name is derived from the Nazca culture, which flourished in the area between 100 BC and AD 800. This culture was responsible for the Nazca Lines and the ceremonial city of Cahuachi. They also constructed additional underground aqueducts, named puquios, in a regional system that still functions today. The first puquios are believed to have been built by the preceding Paracas culture. Nazca is the capital of the Nazca Province located in the Ica District of the Ica region of Peru. Earthquake On November 12, 1996, at 11:59 a.m. local time (16:59 GMT) there was an earthquake of magnitude 7.5 with its epicenter at 7.7 km into the sea. The earthquake almost completely destroyed the city of Nazca and its surroundings. Due to its occurrence during the day, there were only 14 fatalities. Ho ...

Puquio De Núñez
Puquio de Núñez is a small oasis and orchard in the Atacama Desert of Chile. The oasis is irrigated by an underground canal, a puquio tapping Pampa del Tamarugal Aquifer. Puqui de Núñez lies about 10 kilometers south of the nearby oases of Matilla and Pica. As the puquios of Pica and Matilla tap the Pica Aquifer, it is thought that the hydraulic divide between the aquifers of Pampa del Tamarugal and Pica should be between Puquio de Núñez and Matilla. Located 1,187 meters above sea level Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The comb ... (m asl.) the water at Puquio de Núñez is estimated to come from a recharge zone at ~3,000 m asl.

Pica Aquifer
Pica Aquifer ( es, acuífero de Pica) located in Tarapacá Region of northern Chile is one of the most important aquifers of Atacama Desert. The water of the aquifer is tapped by a system of underground aqueducts known as puquios to irrigate the oases of Pica and Matilla. The uppermost part of the aquifer is within loosely consolidated alluvial and aeolian sediments deposited in the Quaternary period. The recharge zone of Pica Aquifer is estimated to lie between ~3,000 and 4,000 meters above sea level. As nearby oasis Puquio de Núñez taps the Pampa del Tamarugal Aquifer it is thought that the hydraulic divide between the aquifers of Pampa del Tamarugal and Pica should be between Puquio de Núñez and Matilla. It is not known if the waters of Pica Aquifer flow into Pampa del Tamarugal Aquifer as these two aquifers are separated by the Longacho fault line. While this fault may deviate and block part of the flow a 2012 study showed a hydraulic gradient Hydraulic head or pi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potosí
Potosí, known as Villa Imperial de Potosí in the colonial period, is the capital city and a municipality of the Department of Potosí in Bolivia. It is one of the highest cities in the world at a nominal . For centuries, it was the location of the Spanish colonial silver mint. A considerable amount of the city's colonial architecture has been preserved in the historic center of the city, which - along with the globally important Cerro Rico de Potosí - are part of a designated UNESCO World Heritage Site. Potosí lies at the foot of the ''Cerro de Potosí'' —sometimes referred to as the ''Cerro Rico'' ("rich mountain")— a mountain popularly conceived of as being "made of" silver ore that dominates the city. The Cerro Rico is the reason for Potosí's historical importance since it was the major supply of silver for the Spanish Empire until Guanajuato in Mexico surpassed it in the 18th century. The silver was taken by llama and mule train to the Pacific coast, shipped north ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pica, Chile
Pica is a Chilean town and commune in Tamarugal Province, Tarapacá Region. Situated in the inland of the Atacama Desert on an oasis, Pica is famous for its small and unusually acidic limes known as Limón de Pica. The town has a communal hot spring with a surface temperature of 40 °C, which makes it a popular bath place in the middle of the desert. It has hotels and all basic services. The town lies four kilometers to the northeast of the oasis village of Matilla. Pica has a mild microclimate that does not display the typical high temperature oscillations seen in many of the worlds deserts. The settlement has pre-Hispanic origins and served as an important stopover for transit between the coast and the Altiplano during the time of the Inca Empire. Bird mummies of pre-Hispanic origin have been found next to Pica. Pica gained prominence over the course of the 17th, 18th and 19th centuries when it grew in association with important mining cycles of nearby areas. The first min ...
