I am at a loss for words. This will be epic. Can't wait.

It has been eaten.

Better rivers picture using recently renewed maps.

The impression of small streams turning into rivers draining into lakes is quite impressive. 

Besides that, i noticed that the deposition is much more prominent and it almost looks more built-up along the slopes. Where there changes made there?

Fine rivers, Daniil! I haven't tested your latest file yet, but I will.

Chris, erosion shader has parameter "Deposition amount" which is set to a high value in this scene.

Thanks Ulco, your trick with added deposition derived from flow map works fine at the landscape with high deposition amount.

Those results looks rather realistic. The sedimentation morphology.

How are the calculation times on such a high value?

Can't wait to try Daniil!
These look amazing!

Deposition amount has almost no any effect on the calculation times.
Current deposition algorithm is very simple and doesn't use any modeling of sediment transport.
Rendering time of this particular scene is 11:40 on my old Mac Pro 8x2.26 (quite close to a modern quadcore i7@2.8 by performance).
Re-rendering time is 7:15 because of erosion cache was filled already.

Very interesting.

Well, you asked for a bigger sedimantation.  ;D Something like this?

This also would be great to become reality. As far as i am aware, no one has succeed with this yet.
