Actually they are evidence of either a change in elevation or a drop in sea level. For example the image that I posted is of Goosenecks State Park. The small river within it is a tributary to the Colorado river. The area was a lowland in the past as shown by the meandering stream. Those do not form in high energy environments. Those are ones where where there is not much elevation change over the length of the river. An uplift can change that. As the land is raised it erodes at the border of the uplift and that erosion works it way upstream. It can freeze the meander in place by causing it to get so deep that it no longer overflows the banks during floods.Incised meanders are typical, nay, proof positive
of rift valley. I heard about that.
That is the first problem for flood believers. It could not have been formed from run off of the flood. The meanders may have existed, but when a flood recedes one gets essentially sheet run off.
The second problem is that the steep sides tell us that the rocks were well indurated. Some of them extremely well indurated. Unconsolidated sediments slump, even more so if they are wet. Since it would have had to have formed after the flood run off, and under essentially today's climate there was nowhere near the time for it to erode its way down. Especially when it first forms large flows would only cause the stream to flow over its banks and flow straight to the sea. Wiping out the meanders. An uplift with slow erosion down of the incised meanders does not present these self contradictions.
I am still waiting for a creationist explanation that either does not form it in the first place, erases the meander, or takes too long since the flow of a small stream simply will not cut that in a few thousand years.
