A Source model consists of two parts - a project file and one or more scenarios. A project file is a wrapper for a collection of one or more scenarios. It identifies the project name, description, and any 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 is used to represent the urban water cycle networks (water supply, stormwater, wastewater), ranging in scale from a single allotment up to large clusters or small subdivisions.
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.

Introduction
The Urban Developer Plugin to Source allows the Source user to add an Urban Developer scenario.
Figure 1. Create an Urban Developer scenario
This section of the documentation will describe how to set up the node components of an Urban Developer scenario (Figure 2.) and how to configure the interactions between these nodes.
Figure 2. Overview of the node components of an Urban Developer scenario
The urban demand is represented by a Water Use node (Figure 3.). Urban Developer offers two methods for simulating the water use at a water use node, either as:
- an Average daily model, or
- a Behavioural model
If relevant, supply can be supplemented by water from a Tank attached to a Roof, represented as two further nodes (Figure 3.) which can be configured.
Figure 3. Urban scenario water use nodes
Urban Developer represents urban demand at the node by simulating individual end-uses at the household level. Currently represented end-uses include:
- outdoor/variable;
- shower;
- washing machine;
- toilets and
- indoor hand taps and dishwashers
End-uses such as baths and leaks are not modelled explicitly, but can be lumped with the outdoor/variable end-use. Separating demand into individual end-uses provides the user with the flexibility to apply different supply sources for each of the types of end-use.
