This calculated much quicker than I expected.

What's this Henry; I just get some google+ page...
There should be a link on my Google+ wall. I uploaded it to YouTube. It's so random, well it sucks to be honest. I was hoping for some insight of how to do this.
Basically, it's a small, low detail, low AA test of the flow distance of the erosion operator for heightfields. I wanted to see how the increase of the flow distance looks as the value increases. It did this, but the terrain wiggles around like jello.
I think the only way to fix this would be to save the heightfield after every erosion calculation. Render the image, then load the saved heightfield and calculate the next value/s.
Here's the link to the YouTube anim. http://www.youtube.com/user/njeneb?feature=mhum#p/u/0/dpgEMr0H5_I
