The sediments that the ancient channel is cut into or buried by can be unconsolidated, semi-consolidated, consolidated or lithified. … See more A palaeochannel is distinct from the overbank deposits of currently-active river channels, including ephemeral water courses that do not regularly flow (such as the Todd River, Central Australia) because the See more There is a large palaeovalley underneath Anangu Pitjantjatjara Yankunytjatjara (APY lands) in the remote north-west of South Australia. See more • Sedimentology • Erosion • Ore genesis • Paleoshoreline • Placer mining • Uranium ore deposits See more Paleochannels form when river channels aggrade and so deposit sediment on their bed. For the channel deposits to be preserved, the flow … See more Palaeochannels are important to geology for a number of reasons: • Understanding movements of faults, which may redirect river systems and so form stranded channels … See more Palaeochannels can host economic ore deposits of uranium, lignite, precious metals such as gold and platinum, heavy minerals such as tin, tungsten, and iron ore preserved as paleo- See more

During the past 20 years, a controversy, or at least a difference of opinion, has developed over the relative merits of deterministic and random models in fluvial geomorphology. A … WebJ.P. Miller’s (1923–1961) Fluvial Processes in Geomorphology demonstrated how geomorphology could become more process-based. 1965 S.A. Schumm (1927–2011) and R.W. Lichty recognized steady, graded ...

Old channels, however, have small bankfull flows, high sinuosity, small meander wavelength, gentler gradients, and are relatively stable. The multiple channels develop by avulsion.
