By the way: it depends on the detail!
Pre glacial reconstruction of watersheds from isostatical
land-level-changes (ger. Ausgleichsbewegungen) were done for noth
america. I think it was last year.

That erosion processes are highly non-linear. Running physical based
erosion models in "backwards-mode" is not possible I would bet.
I guess one have to work with ground layers, geological land rising and
lowering, climatic changes and so on.
But well-wrought concept ideas are always welcome.
One can't turn back time, still I also have been thinking about
playing with erosion models in backwards mode. If it's possible to
calculate current erosion rate and eroded material ammount, it should
be possible to add erroded material to DEM, repeat erosion model run
on new DEM and in such way ba
Hi,
that mean, as I understand, that you have to have a paleo DEM.
You have to ask the question:
On what data basis do I want to reconstruct paleo landscape?
Geomorphological changes cannot be reconstructed just with a present day
DEM.

Can anyone suggest a method to backward model a river system's flow path that
can integrate with srtm data?
I am seeking a way (if possible ) to look back in time at the paleo-course of a

I have no doubt that a solution would be a complex undertaking - could anyone
