Elevation III: They're Trying to Wash Us Away

The erosion tests work beautifully.

after 10 erosion cycles

The key here was to increase the number of total cycles. The erosion depicted here is 10 cycles, about 2.5 million years. It yields a very nice fractal terrain that looks much more like what you might see in real life. There is still some tweaking I can do to optimize the relationship between the amount of drainage and the amount of erosion or uplift.

I'm going to "reset" the results, however, until the precipitation maps are complete and I've quantified the effect of rainfall on the drainage amounts.
