Make particles in a particle layer change direction

[Equalrights4animals]

I'm trying to create an effect of water flowing over a waterfall and I was thinking the best way to do that would be to have a particle layer and make the particles change direction and move down when they reach the waterfall. How would I do that or is there a better way to create the waterfall effect?

Easiest way would be to set up separate particle layers for flowing, falling, and spraying water, and blend them together with blurry masks.

Thanks. What's a blurry mask?

Any layer you use as mask can be blurred.

I recently followed this tutorial to create a waterfall and it worked very well.

You can use a similar technique "control" the particles direction using follow path. I think I posted that in the forum some years ago, but I don't remember where.
Anyway, check this file:

The "particle" layer is following the "path" layer. If you animate the path, the particles follow that animation.
