Hello,
I have been trying to create a Flow accumulation raster with input a flow direction raster. I follow the exact steps than provided by many tutorials, but it simply doesn't work. I have read about changing the parallel processing option, but also without success. I've also tried to resample my raster (as it is quite big) but also without success. The flow accumulation tool is running up to 75% in 10min but does never go beyond that even after letting run over 24hours. It's been a week of trial and continuous errors.
I'm working with ArcGIS Pro 2.8 and a DEM of size 58.28 MB.
Any help is much appreciated!
Thanks!
