I was going to comment that a beach has to meet the water at the same
level. That is maybe sort of implied above? As opposed to a cliff or
even wall.

I am not sure that a beach is required to have a "significant" slope.
Obviously it must have some non-zero slope, otherwise it will be covered
by the water (to a first approximation). But on reflection, even that
may not be true for some sections of a beach. Portions that may be
exposed at low tide could even have a negative slope, and still be a
(hazardous) beach.
