In various parts of the world major waterfalls are conspicuous landscape features and tourist attractions. Mapnik fails to render these at all with the result that certain waterfalls have been 'tagged for the renderer': e.g., Iguazu and Rheinfalle.
It is suggested that waterfalls pretty much fall in the same class as cliffs and barriers and can be treated using the same rules. Furthermore the type of line symbolizer required for waterfalls is similar to that of cliffs (a line, with some ornamentation on the lower (downstream) side).
Light experimentation suggests that the following changes are required:
Create 2 new line symbols "wfall.png" and "wfall2.png". Example of latter attached.
Create a new style, along these lines (basically 'cliffs')
Alter the layer 'line features' along the following lines
cliffs
waterfalls
barriers
mapnik

(select way,barrier,"natural",man_made, waterway from planet_osm_line where barrier is not null or "natural" in ('hedge','cliff') or man_made='embankment' or (waterway='waterfall')) as roads
