The Geographic Wizard is the first in a series of steps required to create a catchments scenario. It consists of a structured sequence of windows that guides you through the process of defining the catchment area. On completion of the wizard, you will be presented with a node-link network. This figure outlines the sequence of steps in the wizard.
If some data or parameter values are unavailable whilst creating the scenario, skip the step by clicking Next. Once you have created a scenario, you can make changes using the choices on the Edit menu.
In some situations, the wizard will skip over several steps if certain values have not been specified. For example, if you do not define any constituents (step 4), you cannot assign inputs or parameterise any constituent-related steps. Therefore, steps 8-13 will appear greyed out in the wizard progress indicator (Figure 2). This figure also shows the action buttons that are visible at the bottom of every screen in the wizard.
