"WebBraided river channels are broad and shallow and found in areas where sediment is easily eroded like at a glacial outwash, or at a mountain front with high sediment loads. [1] [2] These types of river systems are associated with high slope, sediment supply, stream power, shear stress, and bed load transport rates. [2] " - Alluvial channel

WebPalaeochannel. In geology, a palaeochannel, palaeovalley, or palaeoriver (US spellings paleo-) is the remnant of an inactive river or stream channel that has been filled or buried by younger sediment.
