Australian Water Information Dictionary
An artificial or constructed waterway designed to convey water. Often described as open channels to distinguish then from pipes, channels can be categorised as: main (or major) channels whose primary purpose is to convey bulk water from headworks storage or river diversion points into the distribution system; or distribution channels whose primary purpose is to deliver water from main channels to individual farms. The term canal may sometimes be used for main channels that are used for other purposes than just conveyance of bulk water, such as recreation or transport.
