Very likely, the output of ncdump is not what the SWAT model expects.

You will likely need to do some programming to accomplish this task. Start
by understanding the specific format expected by your model. Then take a
look at this recipe and adapt it as needed:

If you know python, this recipe may be useful:


http://cookbooks.opengrads.org/index.php?title=Recipe-003:_Using_PyGrADS_to_save_variable_data_to_a_text_file

All of this assumes that your netcdf file can be read by grads.

 Good Luck,
