A Source model consists of two parts - a project file and one or more scenarios. The project file is a wrapper for the scenarios. It identifies the project name, description, and the scenarios associated with the project. A scenario represents the major processes in a water resources system using Source's node-link framework.
An Urban Scenario in Source is used to represent an urban water demand.
Once the Urban Developer Plugin has been installed, Urban Scenarios can be created like other scenarios in the core Source framework. Refer to Projects and scenarios for details. Figure 1. shows the main user interface for an Urban Scenario.
