The water covered area of a river, used with natural=water. Should contain a waterway=river way inside.

Also see the more common tag waterway=riverbank

How to Map

Draw the outline area of the river and add natural=water + water=river.

For long rivers the area should be split into several segments of manageable size (Area 1 and Area 2 in the image below).

In addition a way way tagged as waterway=river, must be drawn in the direction of the river flow (way 4 in image). All tags of the river (like name=* and other supplemental tags) should go to this center line.

More information on river area mapping can be found under waterway=riverbank.

Islands

To map islands in a river you can use a multipolygon relation and the island and the main river bank should be included in the relation. The main riverbank way (way 1 in image) will have the role 'outer' and the way for the island (way 2 in image) will have the role 'inner'.

Alternative

The area of the river is tagged with waterway=riverbank alone - this tagging is several times more common
