[Qgis-user] Watershed - Catchment area upstream of a point

[Tony Shepherd (FarmMaps NZ)]

Hi All

 

I'm wanting to use a DEM/DTM to automatically map the watershed/catchment
area upstream of a known point.

 

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? 

 

Cheers

Tony
