Adding to Warin's comment to mention a thing that wouldn't often (ever?)
appear in Western European mapping ...

How do you map a river course that in the wet season is 100's of m wide,
but in the dry season may only be 5m wide / a series of puddles / not there
at all?

& interestingly, I was looking at this page earlier after a reference to it
on another thread:
https://wiki.openstreetmap.org/wiki/One_feature,_one_OSM_element

Part of it:
Situations where multiple elements may be needed
*Rivers* are usually represented with waterway
<https://wiki.openstreetmap.org/wiki/Key:waterway>=riverbank
<https://wiki.openstreetmap.org/wiki/Tag:waterway%3Driverbank> or natural
<https://wiki.openstreetmap.org/wiki/Key:natural>=water
<https://wiki.openstreetmap.org/wiki/Tag:natural%3Dwater>+water
<https://wiki.openstreetmap.org/wiki/Key:water>=river
<https://wiki.openstreetmap.org/wiki/Tag:water%3Driver> for the area
covered by water and waterway
<https://wiki.openstreetmap.org/wiki/Key:waterway>=river
<https://wiki.openstreetmap.org/wiki/Tag:waterway%3Driver> on a linear way
that follows the main flow of the river, with tags such as name
<https://wiki.openstreetmap.org/wiki/Key:name>=* on the waterway
<https://wiki.openstreetmap.org/wiki/Key:waterway>=river
<https://wiki.openstreetmap.org/wiki/Tag:waterway%3Driver> feature. It is
necessary as entire river mapped as a single area would be so large that it
would cause major performance and maintenance issues.

:-)

Thanks
