Thanks for explanation. It works correct now!

Thanks for the answer, will try it out.

I am using Saga gis ver 6.2. Trying to calculate Isochrones..Manning's n is not estimated in the calculations. I am running variable speed, adding different n values, but it comes out as the same.. CN values, Slope, Rainfall intensity are used in calculations, but the n value dont seem to have any impact on the result..Why? and how to fix this bug ?
