I'm hoping there might be an easy answer to this question.

I have an existing height map in bmp format that I like the looks of. The problem is that some of the shore lines and river edges are almost grossly cliff like instead of being gradual rises. I've experimented with Wilbur a bit to see if I could smooth this out some and have had no luck what so ever, so my question is;

Is there an easy way within Wilbur to smooth these areas out such that the shores along the rivers and coastal regions aren't so aggravated? I know I can do this sort of thing in my graphics editors, however, doing so steals some of the detail away from areas beyond these shore lines. I tried following Joe's latest tutorial (Fun with Wilbur 4), but that didn't seem to do the trick.

In a semi-related question, I've been fiddling with the Erosion Cycle in Wilbur and understand that this may take a while, but is there a definition of "a while?"
