Anabranching

Work on anabranching channels has been restricted mainly to the alluvial plains of the Murray and the Murrumbidgee, where the anabranches -- offshoots -- rejoin the original trunk or unite with a next-neighbouring trunk, sometimes after a distance of tens of miles.

In particular, logjams blocked channels and led to the formation of side channels and floodplain sloughs, producing multiple anabranching channels and riverine wetlands that are in stark contrast to the large, single channels that exist in these streams today.
