How to Map
To map a river make a simple way. Add the waterway=river tag to it. The direction of the way should be downstream (ie draw the way in the direction that the river flows).
You should also add a name with name= if it's known.
For larger rivers you may want to create separate ways for the two river banks. See Tag:waterway=riverbank
Do not add natural=water to the way since this is intended for areas forming lakes.
Extended Tags
width=* to indicate the width in meters. This is an approximate average width of the river throughout most of length of that bit of river. You can use width=5 or width=5 m to tag a river with a width of 5 meters.
Direction of Flow
The OSM convention is that the way should be drawn in the direction the river flows. If you are drawing a way and you are unsure of the direction the water flows you could add a tag such as "fixme=direction unknown" to the way.
