Hm okay this doesn't look too bad.

This is a small bit of dumb C code doing rather naive river sediment transport. I thought I had a notion of how to generate meanders without the full complication of the CHILD model I was trying to run before, but it would need some nice big flat river valleys and this is only generating pretty mountainous textures.
Same initial conditions different parameters:
