Hi, I want to do a coupling simulation using the Hydrus-1D package for Modflow 2000.
I encountered a question regarding this issue, In the Hydrus-1D model according to the image I sent, a text file based on the conditions considered for the soil Profile can be exported as input for Modflow, is this text file sufficient to be added Modflow files directory and run modflow? Or Should changes be made to it? Are any other changes needed in this text file?

You should read the help topic for this commend. This command creates HYDRUS input files for a special version of the HYDRUS package for MODFLOW as described by:
