“Kimberley–Perth Canal”的意思、由来-开放百科全书

The Kimberley–Perth Canal is a proposal to channel water from the Fitzroy River in the Kimberley region of Western Australia via the Pilbara, to the southwestern capital of Perth, a distance of approximately {{convert|3700|km|mi|0}}.^[1]

History

In the late 1980s, Water Resources Minister Ernie Bridge proposed a water pipeline from the Kimberley.^[2]

In 2005, infrastructure company Tenix proposed the idea of a $2 billion, {{convert|7|m|abbr=on}} wide canal as a solution for Perth and the Western Australian region's water problems.^[3]

The canal proposal was presented as part of Colin Barnett's unsuccessful 2005 state election campaign.^[4]

As opposition leader, he ruled it out when campaigning for the 2008 election.^[5]

In 2012, following Perth's driest July on record, Premier Barnett raised the proposal again, saying that "from a technical or engineering point of view, it's not difficult to do".^[6]

Water source

The Fitzroy River, with its catchments fed by variable tropical rainfall, is reported to deliver 9,200 gigalitres of mean annual flow,^[7] and at peak floods is stated as being "probably the largest river in Australia"{{citation needed|date=August 2012}} when it has been reported to discharge up to 30,000 cubic metres per second into King Sound and the Indian Ocean.{{citation needed|date=August 2012}}

To prevent damage to the river, the surrounding environment and fish, surplus wet-season flood flow would be pumped from the river {{convert|60|km|mi|0}} inland from the coast and transported by canal, avoiding interference with the eco-sensitive flood plain, then stored by aquifer recharge in and re-gathered from the La Grange Aquifer – a {{convert|280|km|mi}} long natural underground lake – to provide a variable wet-season buffer supply.{{citation needed|date=August 2012}}

Environmental issues

Environmental groups generally consider Kimberley water should not be developed at all, and the World Wildlife Fund cited a 1993 WA Government report stating that aquifers in the Fitzroy River had volumes of not much more than {{convert|200|Gl|cuyd}} and that the pipeline or canal requirements would cause serious environmental damage.
