Billabong \Bil"la*bong`\, n. [Native name.] In Australia, a blind channel leading out from a river; -- sometimes called an anabranch. This is the sense of the word as used in the Public Works Department; but the term has also been locally applied to mere back-waters forming stagnant pools and to certain water channels arising from a source.
n. (context hydrology of a water channel English) A diverging branch of a river, creek, or stream which re-enters the main stream.
An anabranch is a section of a river or stream that diverts from the main channel or stem of the watercourse and rejoins the main stem downstream. Local anabranches can be the result of small islands in the watercourse. In larger anabranches, the flow can diverge for a distance of several kilometers before rejoining the main channel.
