If there is another part of the forum where this would be more appropriate, please let me know.
Using the hydrology toolset and a digital elevation map, I was able to draw the stream network of my thesis area. I have it drawn as a raster, and as a polyline shapefile which I created from the raster.
In the field, I performed direct measurements of river discharge. I would like to re-draw my stream network so that the width of each stream is proportional to the volume of water flowing through it.
I don't even know where to begin with this, so any suggestions would be appreciated.
Use the tool to create the stream order and then use Quantities/proportional symbology.
PS - This results in a raster. You then have to convert the stream raster to a feature to get the polylines that have a grid code based on the stream order. Use proportional symbology based on the grid code.
