Hooray! Whitewater simulation!
What this ten-part tutorial can do: over two and a half hours of tips & tricks on: terrain creation, FLIP simulation, whitewater source settings and whitewater simulation. You can also learn how to customise materials, rendering and compositing.
For a fee of 280 US dollars, you can work your way through the Houdini Waterfall Tutorial by VFX Grace. Only rafting on a white water course is better!
