Hi Rainer, I'm also calculating the topographic wetness index (TWI) via the python API. Mine saga version is 8.30. As you explained, the No.0 tool of ta_hydrology no longer outputs the catchment area. Do you know any equivalent tool to calculate the catchment area in terrain analysis? I find early versions have specific tools to calculate catchment areas. Do I have to roll back to do this work? Thanks, Wenlong
