Dry stream bed - negative forms of erosion relief formed by the activity of temporary streams.
Small dry natural channels formed by temporary water streams can be found at the bed of ravines and small valleys, river terraces and on the valley slopes. These landforms characterized by small plunging, tortuosity and similar appearance.
- waterway=drystream should be considered as an element of relief, not hydrography.
- waterway=drystream used in the designation of those dry stream beds, where there is no water for several years. To indicate seasonal streams, which is the item hydrography, use tags waterway=stream + intermittent=yes
- Those dry channels can be filled with water during snow melting and heavy rains. If they stay filled with water more than 3-4 weeks, then tags waterway=stream + intermittent=* should be used.
How to map
Draw the line along the bed of the channel and add tag waterway=drystream.
Use width=* to specify approximate channel width.
