Hi Tony, Just wondering....
If QGIS is using SAGA to do the work, have you considered installing SAGA & using it directly?

After a bit of reading, this appears to be a not-so-simple task but suggestions are to use the “Upslope Area” algorithm. In my case, the program fails to finish running, and the message window shows the following error: SAGA Version: 7.8.2 (64 bit) Error: tool needs graphical user interface [Upslope Area] C:\Users\Tony\Documents>exit Questions: * Does anybody know what that error means? * Is there another tool/method that is preferable to use?
