I'll suggest that you run the WaterShed Tool on the data. It will give a raster which indicates each watershed in that area, and then you can see whether each cell in your study area drains in the same creek or Sink.

What you refer to as half basins are often called hillslopes. I'm not aware of any tool in GRASS GIS that can extract these features from a stream network and a DEM, although it is possible that I have overlooked the correct tool. However, if you are open to using alternative open-source GIS then I can recommend the hillslopes tool in Whitebox GAT, for which ...

I've struggled with the same problem for a while. Even when they were in the same CRS the elevation and catchment grids were out by a couple of meters. I think it has something to do with the raster resolution and pixel size. I was able to get around this error by setting the pixel size to a round number (eg 5) when interpolation of the Elevation layer when ...

An alternative way of achieving this is to convert each layer into a raster where the polygon is given a value of 1 the background 0. You then add all your rasters using the raster calculator. The resulting raster is 1 or more for where the channel has been and zero for where it has never been. You can then easily extract and convert the zero pixels back ...

1) Create a new Feature Class (FC) in a File Geodatabase (FGDB). Making sure the new FC has the field and field types you need to capture the attribute data from the various 14 layers. Hopefully they are all the same. 2) Import the 14 layers into the newly created FC (R-Click FC, Load --> Load data...). 3) Start an edit session on the new FC. 4) Use the ...

When I have seen that error it has often been because the coordinate systems do not match. Certain processing tools require input data sets to be in the same coordinate system to work properly, even if they otherwise appear to be correctly located onscreen. That would be the first thing I check.
