- Water transportation
Water transportation is the intentional movement of
waterover large distances. Methods of transportation fall into three categories:
Aqueducts, which include pipelines, canals, and tunnels,
*container shipment, which includes transport by
tank truck, tank car, and tank ship, and
*towing, where a
tugboatis used to pull an icebergor a large water bagalong behind it.
Due to its weight, the transportation of water is very energy intensive. Unless it has the assistance of gravity, a canal or long-distance pipeline will need
pumping stations at regular intervals. In this regard, the lower frictionlevels of the canal make it a more economical solution than the pipeline. Water transportation is also very common along rivers and oceans.
Major Water Transportation Projects
Grand Canal of China, finished in the 7th Century AD and measuring 1794 kilometres.
California Aqueduct, near Sacramento, is 444 miles long.
Great Manmade Riveris a vast underground network of pipes (1600 kilometres) in the Sahara desert, transporting water from an immense aquiferto the largest cities in the region.
Kimberley Water Source Projectis currently underway in Australia to determine the best method of transporting water from the Fitzroy River to the city of Perth. Options being considered include a 3,700 kilometre canal, a pipeline of at least 1,800 kilometres, tankers of 300,000 to 500,000 tonnes, and water bags each carrying between 0.5 and 1.5 gigalitres.
