Yes, rivers can be tidal without their flow reversing. The water level can rise during the rising tide but still flow toward the sea. tidal=yes is a fairly common tag. >Also, one needs more values: >flow_direction=forward|backward|tide_dependent|operator_controlled|... >default value: forward LGTM I'd advise against any up/down value because the question normaly only arrises when the relief is fairly flat. -- Vincent Dp _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
