can slow water cascade?

1. a waterfall descending over a steep, rocky surface. 2. a series of shallow or steplike waterfalls, either natural or artificial. 3. anything that resembles a waterfall, esp. in seeming to flow or fall in abundance: a cascade of roses covering the wall. 4. (in a drain or sewer) a chain of steps for dissipating the momentum of falling water in a steep place in order to maintain a steady rate of flow.

Author, no part of the definition of cascade defines it as "slow water".

nor was that my intention. It also does not state that cascading refers to fast water. It states that it occurs when WATER descends...now if slow water is not in fact water, then you have a point...

cute

But nothing rough.

Er ... not sure how much jawshoewhah has had to do with hay ... but it is pretty rough.

agree with author, I wouldn't say that hay or straw is soft.

So what's soft and rough?
