Sorry, just an addendum, for creating these watershed maps, you need a DEM, older satellite data should suffice for larger maps. I was working on a small scale (16 km2) with a 5m DTM. The process is the same: use WangLiu algorithm in the processing toolbox (SAGA tools) to fill sinks, then

Hi, I just created one yesterday with the book of Hans van der Kwast. So easy! (when you are told what to do...) He has a YouTube channel where you can follow these instructions as well. Best, Maria > Am 07.08.2020 um 07:13 schrieb C Hamilton : > > I was wondering if anyone had any idea on

Watershed polygons and river lines for the US are available from the USGS. You would do a spatial joint between the river and basins to add the basin information to the rivers layer. You would then symbolize the rivers by category, using the basin attribute as the
