I would tend to just mark the river .. not the bank at all. But..
<br>
<br>
However the river bank would be seasonal? <br>
So possibly a seasonal tagging would suit? <br>
<br>
so one area with seasonal=summer;autumn;winter (or dry_season)<br>
and another area with seasonal=spring (or wet_season)<br>
<br>

<div>This is an excellent question that applies to Alaska's
braided rivers as well. As they are without man-made flood
controls or artificial embankments, they run full in the
spring, sometimes tearing out trees and even small islands as
they go, but shrink to a trickle in the summer and winter.
Customarily, we map the maximum extent of the river as
riverbank but that leaves a very mistaken impression when one
observes such rivers in the summer. </div>

<div>Question regarding riverbanks & where they should
be marked, thanks?</div>
<div><br>
</div>
<div>Was doing some HOT mapping a little while back in
Nepal & the area I was working on was surrounding a
river - sorry, I can't remember the exact location?</div>
<div><br>
</div>
<div>The imagery I was working of had apparently been
taken during the dry season as the actual river channel
with water in it was ~30 - 50 m's wide. But the wet
season river (or possibly flood?) channel was very
obviously ~500 - 700 m's wide.</div>
<div><br>
</div>
<div>What should we be marking as the "riverbank" - where
the water is visible "now", or the defined limits of
where it spreads out to in the wet season?</div>
<div><br>

<div>Thanks
