| 释义 |
The Canal Lauca is an artificial channel to divert the waters of the Lauca River westward through a canal and tunnel into the Azapa Valley for purposes of irrigation in the valley and hydroelectric-power generation. Its construction began 1948 and water diversion began 14 years later from a dam located about 16 miles southwest of Lago Cotacotani Lake. The canal lies in the commune of Putre in the Arica y Parinacota Region of Chile. It is {{convert|33|km}} long and has a capacity of {{convert|1.9|m3/s}}.[1] It transfers water from the Lauca River into the Rio San Jose for irrigation{{sfn|Cade Idepe|2004|p=20}} and hydropower purposes; the endpoint of the canal includes the Chapiquiña power plant which produces {{convert|56|GWh/year|MW}}.{{sfn|Cade Idepe|2004|p=21}} Typically about {{convert|0.8|m3/s}} are transferred;{{sfn|Cade Idepe|2004|p=21}} a plan to transfer additional water from Lake Chungara was blocked after litigation by an environmentalist group. The canal was put into service in 1962 and is owned by the government of Chile.[1] As a consequence of the construction of the canal, the surface of irrigated land in the Azapa valley increased. This also led to increased immigration from Bolivia into Chile.[4] The construction of the canal led to protests by Bolivians.[5] The Lauca River originates at the Laguna Cotacotani, which in turn receives seepage water from Lake Chungara.{{sfn|Cade Idepe|2004|p=1}} It first flows due westward before turning south and later back east into Bolivia.{{sfn|Cade Idepe|2004|p=2}} After draining a watershed of {{convert|2350|km2}}, the river ends in the Salar de Coipasa of Bolivia.{{sfn|Cade Idepe|2004|p=1}} References1. ^1 {{cite journal|last1=Justwan|first1=Florian|last2=Fisher|first2=Sarah K.|title=Generalized Social Trust and International Dispute Settlement|journal=International Interactions|date=2017|volume=43|issue=5|page=726|doi=10.1080/03050629.2017.1257490}} [1][2][3]2. ^1 {{cite web|title=Bolivia selecciona 50 familias en valles en de Arica para repatriarlas|url=http://inra.gob.bo/InraPb/paginaController;jsessionid=AF9BE00D41BA56146D722CF2673FCE68?cmd=noticia&id=568|publisher=Instituto Nacional de Reforma Agraria|accessdate=2 March 2018|language=es|date=14 December 2009}} 3. ^1 2 {{cite web|author1=PROCIVIL INGENIERIA LTDA|title=CATASTRO DE OBRAS DE RIEGO Y ELABORACIÓN DEL PLAN DE INVERSIONES AL AÑO 2018 ZONA NORTE - REGIONES DE ARICA Y PARINACOTA A METROPOLITANA|url=http://www.cnr.gob.cl/DivisionDeEstudios/Licitacin%20Mostazal/Catastro_OM_Riego_zona_norte_TOMO%20I.pdf|publisher=Ministry of Agriculture (Chile)|accessdate=2 March 2018|location=Santiago|page=126|language=es|date=2009}} }} Source{{refbegin}}
