What could be the reason for "Channel Network and Drainage Basins" tool not actually find the river / channels. The DEM is from usgs and is in a projected projection. The only thing different between your example is that my area of interest is an island and I had to clip-mask the DEM raster, but that should not have any effect
1. Please check the cell size of the DEM (Larger pixel size may lead to such problem) 2. Do not forget to fill sink 3. Recheck the coordinate system 4. Open QGIS worh grass There can be several reason behind this! I hope it will work. First practise with the DEM attached with this video. Good luck.
