  • Did you try directly with SAGA-GIS (Terrain analysis->Hydrology->flow accumulation->top down). Just to know if the issue resides in SAGA or QGIS. I did try the same with one of my tiff rasters and it worked in SAGA but not in qgis (on manjaro). Using saga might thus be a work around.

Saga version 2.2.7 is not supported. Please compile the 2.2.3 downloading the code from here https://sourceforge.net/projects/saga-gis/files/SAGA%20-%202.2/SAGA%202.2.3/. Do not install from software center (there is 2.2.7 version)

  • It seems to be a bit more complicated. I managed to run SAGA 2.3.1 vector algs in the processing toolbox on Ubuntu 16.10 (no ubuntugis involved), and SAGA 2.2.7 from ubuntugis on Ubuntu 16.04 as well. But I don't know why it works for me and not for others.
