There are some POV examples in these groups from a couple of weeks to a
month back but I can't remember which group/s.

I suppose you would follow the path of a water droplet falling
vertically/other from the sky and taking some soil with it - allowing for
deposition & erosion.
You might try e-mailing the author of  HF-Lab & other HF programs that have
this feature to ask the algorithm.
