An urban waterfall is a natural waterfall located in an urban area that has some man-made changes
done to it, such as enclosing the natural creek above or below the falls into a storm sewer or box culvert or the construction of a bridge or road over the creek above the falls. The actual waterfall itself normally has not
changed, just its natural surroundings have been
changed by man.

storm sewer pipe as shown on this
