[Woodcarver] Re: waterfall

[Ivan Whillock]

The "shape" of the water in a waterfall is very much dependent upon the
surface it is tumbling over and, of course the wind conditions, thus no two 
waterfalls shape the water in the same way.  A rough
under-surface with break the water into turbulent streams.  Over a smooth
surface the water can resemble a drape hanging from a rod, forming expanding
tubes.  Unlike a drape, however, the tubes can separate from the mass.

A good example of this "shape" can be seen at:
