This is true for non-braided but similarly erratic rivers in the states. There are often portions where the river may change its course drastically seasonaly, as well as be taken up entirely during seasonal flood events http://maps.google.com/?ie=UTF8&ll=47.94892,-123.557825&spn=0.017218,0.035319&t=h&z=15 (sattelite image of the Elwha river) see also http://en.wikipedia.org/wiki/Elwha_River I have a hunch that the Elwha and similar sized rivers will render too large in many such areas with the bars. I would suggest a tag eg: "river=braided" that would render the outside > maximum extent (as can be seen in the wiki) > a light grey filled *area* would be perfect as it would very closely > represent how they actually look in the environment > A more general tag might be nice, but I'm not sure there is a more general term. Braided may, indeed be the appropriate term, I'll check out my hydrology text tonight. It is worth noting however that the river channels are not fixed and > constantly change their positions across the braided riverbed This is the case for many younger rivers. I think that's where constant mapping and improvement come in, and for older or well managed rivers the banks are unlikely to change much and are probably the most useful information (maybe combined with mean annual discharge?). -Tyler
