Thanks for the clarification, Pierre.
Actually, I tagged the relation both with natural=water, water=river and
waterway=riverbank as advised in the wiki (see New Tagging) I assume this is
the recommended way to do it?
As for Obrero, I haven't been that far north yet :) I only traced it up to the
point where someone else had traced it. I stopped around Sta Rosa:
http://www.openstreetmap.org/#map=14/15.4214/120.9354
But, yes I agree, that needs to be retraced. It was probably traced from an
old lower resolution satellite image like some of my own earlier work.

Ronny,
It is not necessary fo merge the two relations, Each of these riverbank
polygons must be a closed polygon.
See http://wiki.openstreetmap.org/wiki/Tag:waterway%3Driverbank
For the relation 2411084, you must replaced the Tag natural=water to
waterway=riverbank.
North of Obrero the riverbank must be retraced and the island must be traced
independently from the riverbank. The island will be included in the
relation with the role=inner. The island is in fact smaller and a smaller
river on the right connect to the main river.

*Objet :* [talk-ph] multiple multipolygons for Pampanga River
I've been adding polygons for Pampanga River and some of its contributories,
starting near Mt Arayat and working myself northward, joining up with the
existing multipolygon - http://www.openstreetmap.org/relation/2411084. I then
worked myself southwards until I found another multipolygon for Pampanga River
- http://www.openstreetmap.org/relation/2913607 .
Is there a way to merge these?
Or doesn't it matter that the river is split into several multipolygons as
long as they are joined by shared nodes?
Ronny.
