Master File (file.cio)

This file lists the names of all input files used in a simulation run. The files are grouped in different categories and there is one line for each category. The first column lists the names of the categories. The number of columns per line depends on the number of files in a category. Most files are required for all SWAT+ runs, i.e. they have to be listed in file.cio and the corresponding file has to be present in the TxtInOut folder of the SWAT+ project. There are also some optional files that are only required for specific SWAT+ applications. The category names and their files are listed below.

If a file is not being used for a SWAT+ application, 'null' should be entered instead of the filename.

If the climate files are stored in the project TxtInOut folder, 'null' should be entered instead of the directory.
