 Braided rivers leave a distinctive set of facies behind with deposition that's tied very closely to the dynamics of how the sediment's transported and deposited within the channels. So the channels in braided rivers migrate back and forth, and the deepest part of the flow has, of course, its grain sediments. As the channels migrate, they're eroding away the bars. And so if we plot a typical sequence of rocks, starting with zero at the base of a channel, it's eroding the bar on one side. So it's usually an erosional surface, and the course's grain sediments are at the bottom. And now the course's grain size that's integrated depends on the river itself. We'll make ours have cobbles here, and cobbles can accumulate. They get deposited, brought in by floods, and accumulate. And so this right here represents the base deposits at the base of the channel. As the beds accumulate, the water gets shallower, the bar migrates to the side, and so they often find upward. Usually the flow is so fast that you might not deposit very much of this finer sand. So we'll make ours end, and it looks like about coarse sand. And if we think about the sedimentary structures down here, there might be some planar lamination, but the trough cross stratification is more common. As you get further up into the area here, you can end up with ripples. Or if you remember the bed form diagram, you start to get planar lamination and finer grains at a lower flow speed. And so you might actually have some upper planar lamination in some of the sediment here. So in general, what this change in the channel faces are showing is a finding upward of the sediment and a change in the grain size. So this is at the base of the channel. This part is deposited on a bar that's migrating into that area. And so then at some point the top of the bar might be exposed a little bit. And then the next flood comes, and the flow speed might be fast enough that this gets eroded. Or it could be that just another channel migrates into this area, and this will end up eroded, and the thicknesses vary. So this would be, again, the base of a channel, the main part of a channel finding upward onto the bar. So this would be another channel deposit, and then this would be a channel deposit as well. So if we were going to define faces for a braided river channel, the characteristics would include the sedimentary structures, the grain size, and their relationships to each other. So we could define them as being a group of rocks. The channel faces of a braided river could be a group of rocks that typically has a scoured surface at the base with gravel or cobble lag deposit or conglomerate. And they find upward with a trough cross stratification, a planar lamination, and current ripples in correspondingly finer grain sizes. So that's the channel faces themselves, but we also have overbank deposits. And so the overbank deposits, because the water is still flowing, usually consist of sand and silt, plus soil, and if it's post-divonian and on earth, vegetation. If there is some mud present, they can include things like mud cracks as well. Thanks for watching.
