way to visualize strahler stream order?

Is there any way to set up a "Generate watershed" command to delineate streams according to Strahler's stream order? Also, is there a way to vary different stream's thickness or color based on flow in cubic meters/sec?

While there isn't currently a way to see the Strahler's stream order, each stream will have an IN_FLOW and OUT_FLOW attribute showing how many "cells" flow in and out of the stream. If you go to the Line Styles tab of the Options dialog for the layer you can set up the line style based on one of those attributes. For example set a line width of 1 at an OUT_FLOW of say 500, then a line width of 5 at an OUT_FLOW of 50000, then let it automatically interpolate the widths for lines in between. Of course use whatever actual values work best for you.
Thanks,

Hi,
do you plan to fill the gap ? It will be very interesting to have this function.
