I am working on a project to delineate stream networks in certain watersheds. I have created a stream network (flowlines) from a 1/3 arc second DEM using the hydrology tools (FlowDir, FlowAccum, Con (w threshold) and Raster to polyline). I would like to categorize these flowlines into categories of perennial, intermittent and ephemeral. I am not sure how to do this, can anyone offer advise on how to or where to look for information.
Thanks,
Angela
