With a cliff the high water and low water marks would be coincident, or
very nearly
so.  Unless there is at least enough space for somebody to stand between
and low-water marks, it can't be a beach.

I am not sure that a beach is required to have a "significant" slope.

I wouldn't say a slope is required, just that in the real world there will
be a slope.
The point I think was trying to be made is that the slope isn't vertical or
so steep
that it's difficult to walk on.  But I could be wrong.
