a water flow is there -> waterway=* (the same logic as for highway=*) we already map "hardware" for road (surface) for building (building:material). did we need to delete those ? > In the diagram > https://wiki.openstreetmap.org/w/images/thumb/e/e6/Waterway_flows.png/500px-Waterway_flows.png > > The upper ones may well be man made - so the tags waterway=canal, > tunnel=yes could be replace by > man_made=pipeline .. 1) a tunnel is not a pipeline ! 2) not having a waterway=* is bad beaucase it break the continuity of the water network. By analogy, when a trunk go into a tunnel, we don't replace highway=trunk by tunnel=trunk but we keep a continuity of highway=* network by having on tag for "road network" and another tag for the tunnel it-self.
