Hello everyone,
I am trying to do watershed modeling via ARCSWAT. I could not understand how to create the soil data data file in the HRU input section. I am working in Turkey, so the SWAT database is not useful to me. I download data from https://soilgrids.org/. However, on this page
0-5
5-15
15-30
30-60
60-100
They have depths of 100-200 and different soil types like silt, clay, sand. I downloaded all of them but I couldn't understand how to combine them into a single file. When I searched on the internet, it was written that I could combine them with raster calculator but I couldn't understand it.
There is no open attrıbute file in the raster file. Even if I average all depths, I get different types of tiff files for silt clay sand. In this case, rowid, value and count parts are formed. But I don't know if the way I am following is correct? And I don't know how I can merge the newly obtained files after this stage. Can anyone explain if this method is correct? Or who can tell me the correct way?
Thank you in advance.

Hi, for simplicity purposes please go to QGIS Raster, you will find the "raster calculator" tool with which you can combine them. And you come back to work in ArcGIS with the generated file. Otherwise it can be done on ArcGIS using Arctoolbox.
ArcToolbox > Data Management Tools > Raster > Raster Dataset.
Insert the raster files.
Select the output location.
Specify a name and extension for the output.
Specify the pixel type.
Specify the number of bands.
