<p><font face="Verdana">We could look at it and designate these
features how they develop over time, apply tagging accordingly.<br>
<br>
As long as the meander of the river contains flowing water,
either permanently or intermittent/seasonally it remains a river
and we have sufficient tagging to distinguish those with
natural=water and waterway.<br>
<br>
If the meander becomes cut off from the main river flow, so no
longer contains open flowing water we had no specific tagging,
but I do like the oxbow term for that, although it never went
through a proposal process. Maybe we should promote it's use by
referring to it from other wiki pages.<br>
</font></p>
<p><font face="Verdana">Over time these oxbows due to sedimentation
turn into wetlands. Also there I believe we have sufficient
tagging possibilities.</font></p>
<p><font face="Verdana">Many of these "wetlands" get drained and
reclaimed for human purposes. Others are directly reclaimed
from water bodies like the sea, lakes but also rivers. Those we
tag with landuse.<br>
landuse=farmland seems the correct tag here. We do already use
it for irrigated and drained land by identifying the crops grown
there, like for rice and paddy rice fields. We also have
separate landuse tags for specific farmland, like orchard and
vineyard.<br>
As far as I know we don't have a specific landuse tag to those
purposely reclaimed farmlands from water bodies. Different
crops can grow on it and may are use as pastures.<br>
A worldwide term however exists: polder (<a

So maybe the time and occasion is right to introduce
landuse=polder.</font></p>

<div>Oxbow lakes can persist hundreds of years before they

<div>swamps or bogs (and at that stage should probably be

<div>I don't think you can call it an oxbox lake if there's no
water in it. You</div>
<div>have a transition from water to swamp to bog to
sub-surface differences</div>
<div>that we probably can't map. Maybe, if the surface is
lower than</div>
<div>the surroundings we could map that (except we don't
really have a suitable</div>
<div>tag) until the day comes when river flooding removes even
that</div>
