There are several waterfall objects in the worldbuilder. Getting them to look really good and natural can be tricky, as there are a few issues with them. One of the difficulties is there is a really obvious line where the river changes into waterfall. Use rocks to cover this. Another good tip would be to put some ripplespawnemmiter (another worldbuilder object) at the bottom of the falls to show the water churning up the current.
