A tidal flat, or  mudflat, is a tidally inundated area of bare mud or similar sediments where you will find a lot of birds, crabs, mollusks.

How to map

Draw the outline area of the area and tag it with natural=wetland + wetland=tidalflat.

The area will be located generally outside the coastline.

  • surface=* may be added to specify the surface material: mud, etc.

For rocky foreshore or sand foreshore area use natural=bare_rock/sand/shoal + tidal=yes instead.
