Catchment Definition

The Catchment Definition dialog is accessed from the Model Summary dialog by clicking on the catchment in the catchment summary table.

Click on the rubbish bin icon to delete the catchment from the model. The Delete Catchment dialog will be displayed asking you to confirm that you want to delete the catchment.

Clicking on the cross-arrows icon will zoom the map to the extent of the selected catchment.

The name is required and must be between 1 and 50 characters in length.

Optionally enter a description for the catchment.

A default colour is assigned to the catchment. You can choose another colour by clicking on the colour icon and selecting your preferred colour.

A default opacity of 50% is pre-set. An opacity value of 100% will make the catchment fully opaque while an opacity value of 0% will make the catchment fully transparent. The default value of 50% is a good starting point that in most cases enables information on the current basemap to be visible.

If desired, adjust the number of representatives that you think would be appropriate for the catchment.
