Hello, everyone.
I am currently in the Create HRUs phase.
I have input the raster files of landuse and soil, their lookup table and the csv file of usersoil, and pressed the Read button. After that, I got the following message and could not create HRUs.
There is no crop or soil data for the floodplain of channel 5824 (LINKNO 21531) in subbasin 685 (and perhaps others)
I would like to know the solution to this problem.
I also attach my project file.

One possibility is that you have not projected the landuse and soil maps
to the same projection as the DEM. It is possible to assign projections
rather than reproject. QGIS reprojects on the fly, so you cannot see
the problem. Try pressing the "Zoom Full" and see if your project
splits into two. You should also check the pixel size of theses maps by
checking their properties. Very small values says that these maps are
still latlong maps, not projected.
If the projections are OK check that these maps fully cover your watershed.
