Setting up the model

Once the config has been filled, it should be placed in the same directory as the data directory (Figure 7). User can run the workflow using Command Prompt or PowerShell by following these steps

Figure 7: Directory where the model will be setup and how to open cmd or powershell

1. Open the directory where the data directory and config are located.
2. Click the address bar and type ‘cmd’ or ‘powershell’
3. Press the ENTER key to open the Command Prompt window in the current directory (Figure 7). Note that you can open Command Prompt outside the current directory from the start menu, but the directory needs to be changed to the location of the config using the CD command.
4. Type ‘swatplus_aw’ and press Enter to start running the SWAT+ AW. The workflow will set up the model based on the settings specified in the config (Figure 8). The model being set up will appear in the same directory as the config. If you change a setting in the config, you must change the name of the project too; otherwise, the current project will be overwritten.

Once the model setup finishes, the user can open the model in QSWAT+ and SWAT+ Editor GUI for visualisation. The model project files that are created by the workflow are fully compatible with the GUI, and further changes can be made in the GUI.

Retrieving config and data from existing model

The procedure for retrieving the config and data is the same as for setting up the model. The only difference is that you should not have the config in the directory containing the model. However, if you have the config, make sure you set the Model_2_config setting to True. In that case, the config used to retrieve the new config from the existing model is saved into a directory called old_configs. Thus the user can use previously used configs later. Be sure to move or rename the existing data directory as it will be overwritten in the process.

Running a specific step with "swatplus_api"

The user can run a specific step without runing the whole workflow by using the 'swatplus_api' command. This command should be executed in the directory where the model is setup. if the command is executed without any argument (option), it lists available options as follows

- prepare_project
- delineate_watershed
- create_hrus
- setup_editor_project
- configure_model_options
- setup_management
- write_files
- run_swatplus
- make_figures
- calibrate

To use the api, type: 'swatplus_api [option]' in command prompt or PowerShell and press 'Enter'
