paleochannel means ancient channels, i.e. there were lot many channels in the present desert

1st: transport of sediment determines erosion or deposition - only deposition can balance erosion; second, deposits only form when there is more deposition than erosion.

2nd - or perhaps they're just in a subsiding sedimentary basin.

Well, I guess I screwed up and used the wrong tag (should have used "fact"), so thanks Vsmith. In any case, I replaced the text. Not sure about the quality of the prose, but the facts are there. Awickert (talk) 19:16, 29 March 2009 (UTC)[reply]

A palaeochannel is a vastly different sedimentological feature from a palaeovalley. They are not the same in scale, form, origin, and function. Go see Figure 7.1. Nomenclature for Fluvial Valley Landforms. on page 70 of Response of Later Quaternary Valley Systems to Holocene Sea Level Rise on the Continental Shelf Offshore Louisiana: Preservation Potential of Paleolandscapes, OCS Study BOEM 2020-004 for an illustration and adjacent pages for discussion.
