This item is only enabled if the scenario database contains at least one scenario. The scanning of the scenario database could take a while if you have already created a number of scenarios.
The dialog that appears is separated into two areas: on the left a list is presented containing all available scenarios. Select one by click or enter a name in the entry field at the top of the list.
Selecting a scenario by a single click, the fields in the right area display additional information on the scenario for better identification: substance, catchment, comment and the scenario directory.
To load the scenario, leave the dialog with "OK" or double-click the selected scenario.
If there is already an open scenario with the same title, the specified one will not be loaded. You first have to close the open one.
