Question

I know what a Meander is, but I cannot find a true definition of how a Incised Meander is formed, somebody out ther has had this before

Answer 1

Another landform that can be produced as a result of rejuvenation and uplift is an "incised meander."

The key factor distinguishing incised meanders from normal meanders is that they are cut well below the level of a river's former floodplain.

Incised meanders result from down-cutting along the deepest part of a river's channel.

The down-cutting is so rapid, the river maintains a meandering pattern while deepening its valley. Common along the Ozark and Colorado Rivers.

Answer 2

I agree, kinspirit01 gave an excellent answer. I am also a geologist (as in PG).

Incised meanders can also occur in areas of previous glacial and periglacial activity. For example; at the end of the Late Wisconsinan glaciation, vast torrents of glacial meltwater rushed through the upper Appalachians and Adirondacks down cutting major sluiceways and deep meanders in the mountains. Sometimes the meanders cut so deep they left umlaufbergs, a rounded tall hill or mountain, stranded out in a valley.

Take a geomorphology course. I think you will like it.

Answer 3

it is a meander that has become deepened by renewed downcutting as a result of environmental change. It is usually bordered on one or both banks by vertical walls. Two types can be recognized: Entrenched meander, which shows little or no difference between the slopes of the two valleys of the meander curve; and the Ingrown meander, which exhibis obvious asymmetry in cross-profile, with undercut banks on the outside curve and prominent spurs on the inside

Answer 4

kinspirit01 gave you a great answer. Trust me, I'm a geologist.
(Go look at the Grand Canyon for the great grand-daddy best example of all time).

Answer 5

Try the Colorado Valley - a perfect example............
