Scenarios

Once a WAM project has been created or copied/pasted from another location, the user must either add an existing scenario or create a new one. If the project was copied from elsewhere and had existing scenarios, before doing any edits the user will probably want to make a copy of a scenario so they do not overwrite previous work. If the project does not contain a scenario, which will be the case when using WAM for the first time, the user can choose to create a new scenario, or to copy a scenario from another location.

Creating a New Scenario

If you are starting a new project, or would like to just create a new scenario from scratch in an existing project (Figure 2.8):

1. Right-click on the project folder you want to create the scenario in,

2. Select "Watershed Assessment Model",

3. Select "Create WAM Scenario...".

Creating a WAM scenario.

This will create a new WAM scenario with the default name "New WAM Scenario". As with a new WAM project, it is suggested to change the name so that it does not contain any spaces or other non-alphanumeric characters. Once the scenario has been created, click on the "+" by the folder to open it up and see the contents as shown below

Contents of the WAM scenario window.

There are five subfolders generated by the "Create WAM Scenario" command as well as a default WAM database to hold tabular data for WAM. The directory layout for WAM is discussed in detail in the section Folder Structure and File Storage.
